Comparing the effectiveness between gel and foam hand sanitizers
Authors: Leung Caroline , BCIT School of Health Sciences, Environmental Health  , Heacock Helen , Chen Tina
Published: September 2020

Background: Hand sanitizers are commonly used as an alternative to washing hands with warm water and soap. There are a variety of different hand sanitizers including gel and foam and they are known to kill several bacteria. Many factors play a role in the effectiveness of hand sanitizers such as the alcohol concentration and the techniques used to apply hand sanitizers. Alcohol based hand sanitizers must have an alcohol concentration of 60 - 70% to be effective. There is currently no legislation regulating hand sanitizers and there is a lack of research focusing on differences between foam and gel hand sanitizers. This research study investigates effectiveness of gel compared to foam hand sanitizers by evaluating the prevalence of Escherichia coli (E.coli) on pigskins. Methods: To compare the hand sanitizers, microbiological sampling was completed. E.coli was introduced onto 65 pigskins. Five pigskins were used as a baseline to determine the average amount of Colony Forming Units (CFUs) of E.coli present prior to the application of hand sanitizers. One set of the 30 pigskins was applied with gel hand sanitizer, whereas the other 30 was applied with foam hand sanitizer. The pigskins were swabbed with QuickSnap swabs and plated onto 3M Petrifilms. The 65 petrifilms were incubated at 35oC for 48 hours. After incubation, the CFUs of E.coli present on the petrifilm were enumerated. The difference in CFUs was calculated to determine the reduction in E.coli and the overall effectiveness of hand sanitizers. Results: The data was analyzed by using the statistical software, NCSS. Statistical analysis showed that the findings were statistically significant and the null hypothesis (Ho: no difference in CFUs of E.coli between foam versus gel alcohol-based hand sanitizers) was rejected with a power of 0.9997 at p-value of 0.00000. This indicates that there is a difference in the ability to reduce E.coli between gel and foam hand sanitizers and gel sanitizers appeared to be more effective. Conclusion: These results indicate that there was a difference in the effectiveness between foam and gel hand sanitizers in reducing E.coli that was inoculated onto pigskins. However, consumers should be aware that hand sanitizers do not completely eliminate all pathogens. Though gel hand sanitizers are more effective, they should only be used when there are no other methods of keeping hands clean.

Published: September 2020

Background and Purpose: Seafood makes up a significant portion of the diets of people around the world. Especially fatty fish such as salmon and herring, seafood items contain numerous nutritional benefits including omega-3 fatty acids which studies have shown aid in cognition and memory. However, due to natural and anthropogenic sources of pollution, contaminants such as mercury which studies suggest decreases cognitive functioning if consumed in excess bioaccumulate in marine life including various fish and shellfish species. The purpose of this study was to categorize participants into either the “fish” group (more fish than shellfish consumed) or the “same” group (either more shellfish than fish consumed or equal amounts of fish and shellfish consumed) via a seafood frequency questionnaire, and to administer a memory test to the participants to determine whether there is a significant difference in mean memory test scores between the groups. Methods: 31 participants were randomly selected at BCIT to participate in the study. Participation was voluntary and participants were given written and oral instructions on how to complete both the seafood frequency questionnaire and memory test. Memory test scores were based on the length of the longest digit sequence that the participant was able to recite upon hearing the examiner list the sequence. The highest possible score was a 10, while the lowest possible score was a 1. Results: The mean memory test scores of the groups, “fish” (more fish than shellfish consumed) and “same” (either more shellfish than fish consumed or equal amounts of fish and shellfish consumed), were 5.83 and 5.92, respectively. The median memory test scores of the groups, “fish” and ”same”, were both equal to 6. The standard deviations of the groups, “fish” and “same”, were 1.2004901 and 0.9540736, respectively. The ranges of the groups, “fish” and “same”, were 4 (minimum) to 8 (maximum) and 5 (minimum) to 8 (maximum). From the non-parametric Wilcoxon Rank sum test, the P-value was found to be >0.05 at α = 0.05. Conclusion: The results of this study suggest that diets relatively high in fish are neither positively nor negatively correlated with memory. However, the limitations of this study in combination with the various studies that contradict this study’s findings illustrate the need for further research.
Assessing the risk of lead exposure to children from drinking water in Metro Vancouver child care facilities
Authors: Quach Thomas , BCIT School of Health Sciences, Environmental Health  , Heacock Helen , Afshari Reza
Published: September 2020

Background: Environmental lead exposure has been a concern since the early 1970’s. With the reduction of airborne lead for inhalation, ingestion from food and water has become the major route of exposure leading to elevated blood lead levels. Previous research and the recent lead contamination of drinking water in Flint, Michigan demonstrate the vulnerability of young children and potential for exposure through drinking water. The purpose of this study was to assess and characterize the risk of lead contamination of drinking water for Metro Vancouver-area early childhood care facilities, and the effect of flushing fixtures as a control measure. Method: 91 drinking water samples were collected from various fixtures at 16 child care facilities at progressive time points to observe the effects of flushing and re-stagnation on total dissolved lead content. Analysis was performed using Varian AAS-240 coupled with GTA-120 graphite furnace atomic absorption spectroscopy. Results were analysed statistically using Excel 2010 and SAS/STAT® 14.2 software with SAS Studio 3.6 interface. Results: The mean (SD, min-max) lead concentrations of the water samples were 0.69 (2.32, 0.1-11.27) μg/L at zero minutes of flushing, 0.21 (0.44, 0.1-2.19) μg/L after one minute of flushing, 0.15 (0.17, 0.1- 0.87) μg/L after five minutes of flushing, 0.18 (0.17, 0.1 -0.64) μg/L after re-stagnation, and 0.31 (1.20, 0.1-11.27) μg/L overall. One outlier sample had a lead concentration of 11.27 μg/L, which exceeded Health Canada’s maximum allowable concentration of 10 μg/L. The decrease in mean lead concentration between zero minutes and one minute of flushing was statistically significant (p=0.0020). Conclusions: The results indicate that lead contamination of drinking water in child care facilities is present but below regulatory action levels under normal circumstances. The flushing of fixtures for at least one minute was shown to be effective in lowering lead concentrations further. Efforts should be taken to identify facilities at higher risk of lead contamination and to educate operators of flushing as an effective control measure.
Determining the accuracy of colorimetric pH testing compared to potentiometric methods
Authors: Allan Derek , BCIT School of Health Sciences, Environmental Health  , Heacock Helen
Published: September 2020

Background: Bacterial growth in foods can be prevented by applying various controls to the food product, including adjusting the acidity of the food. Research has indicated that a pH level of 4.6 or lower will be effective to prevent most bacterial growth. In order to verify this level has been achieved pH test strips (colorimetric) or a digital calibrated pH meter (potentiometric) can be used. This study attempted to quantify the degree of accuracy that pH test strips have compared to the calibrated pH meter. Method: MColorpHastTM pH indicator strips with a pH range of 0-14 were tested against a calibrated Extech pH100 meter. In this study 40 samples of rice were acidified to varying levels. Each sample was measured with both colorimetric and potentiometric method. Results were compared to determine the level of accuracy of the pH test strips. As well, test strips were used to measure pH in a variety of different coloured preserves. Results: A two-tailed test showed that there was a statistically significant difference between the readings from the pH test strips and the digital pH meter (P=0.0003). Conclusion: Based on the results, it can be concluded that both methods of measurement are not equally accurate. A calibrated pH meter will give more accurate readings of pH levels and should be used in most cases to confirm food safety with a high degree of confidence. In testing dark coloured jellies and preserves, pH test strips should not be relied on as they will be stained by the food, making the colorimetric reading difficult to determine accurately.
Environmental health officers and climate change adaptation in British Columbia
Authors: McKelvey Laura , BCIT School of Health Sciences, Environmental Health  , Heacock Helen
Published: September 2020

Background: The average annual temperatures in British Columbia have been steadily increasing in recent history and are expected to continue to rise. Climate change impacts have a significant effect on public health, and adaptation to these changes is necessary. Environmental health officers (EHOs) are in a position to deliver climate change adaptation programs in public health. The purpose of this study was to assess EHO perception of climate change adaption and identify knowledge or policy gaps. Methods: A self-administered online survey created used Google Forms was distributed through e-mail and social media to EHOs in BC. The survey asked for demographics information, beliefs about climate change, adaption, and public health. Chi-square tests and descriptive statistics were used to analyze results. Results: There was a significant association found between working in a mixed urban and rural environment and the incorporation of climate change adaptation into practice and the belief that climate change has impacted public health in BC. No association was found between years of experience and incorporation of adaptation. Conclusion: While EHOs generally recognize the public health impacts of climate change, there are many barriers preventing EHO involvement in climate change adaptation.
Evaluation of the daycare mangers’ knowledge, attitude, and practice on lead in drinking water at daycares licensed by the Fraser Health Authority
Authors: Lin Jill (Chang-Jung) , BCIT School of Health Sciences, Environmental Health  , Heacock Helen , Afshari Reza , Shaw Fred
Published: September 2020

Background: Daycares in BC fall under the Community Care and Assisted Living Act which require all daycare facilities to provide a safe environment, including drinking water. Young children who have been exposed to lead in drinking water at schools and daycares can incur serious health effects, including damage to cognitive development. Previous research has demonstrated that even low levels of blood lead concentration are associated with intellectual disability, slowed growth and development, lowered ability to concentrate, decreased academic achievement and behavioural problems. Individuals’ knowledge, attitude and practice (KAP) on drinking water can influence on how the children consume drinking water and potentially cause adverse health effects. This study evaluated daycare managers’ knowledge, attitude, and practice (KAP) on lead in drinking water related to this issue. Method: This study was conducted by collecting 106 responses from a KAP survey to evaluate the knowledge, attitude, and practices regarding drinking water contaminants. The survey was distributed to daycare managers in Fraser Health region. The responses were analyzed with regression and correlation, one-way ANOVA, and chi-square tests. Results: There was a statistically significant correlation between the age of daycare manger and their knowledge (t-test = 0.0309). All other tests showed no statistical correlation, difference, and/or association (p-value greater than significance level of 0.05 on all parameters) between managerial experiences, age of managers, types of daycares in their knowledge, attitude, and practice regarding lead in drinking water in daycare facilities. The data of KAP questionnaires indicated that most daycare mangers do not fully understand and not are sufficiently educated regarding lead toxicity in drinking water. Conclusions: The results of KAP surveys showed that an educational intervention by the government or local health authorities is highly recommended and needed to improve the daycare managers’ knowledge, attitude, and practice regarding lead in drinking water. Additional research is required to confirm this.
Mean difference of coliform counts in relation to sanitation frequencies at the Simon Fraser University Childcare Society
Authors: Chiu Jackie , BCIT School of Health Sciences, Environmental Health  , Heacock Helen , Karakilic Vanessa
Published: September 2020

Background: Young children in child care facilities are more likely to contract communicable diseases than if they are cared for at home. The relationship between pathogen presence and frequency of toy sanitation at these facilities is not well studied. Thus, the discrepancies currently seen in the hygiene guidelines between health authorities in British Columbia, Canada. Most childcare facility studies in the current literature focus on gastrointestinal outbreak situations or the sanitation of multiple surfaces. The focus of this project is on toys only. Toys made out of wood were selected because research shows that this material is more susceptible to harboring bacteria on it. Microbiological swabbing was performed to measure the effectiveness of the sanitation schedule of a child care facility in Burnaby. Method: Twenty-four wooden blocks were randomly selected for surface sampling. The 3M™ Quick Swabs were used to collect the bacterial coliforms before and after sanitizing the blocks, whereas, the 3M™ Petrifilm™ E. coli/Coliform Count Plates were used to enumerate the bacteria. The last time the facility had cleaned the blocks was 1.5 weeks prior to sampling. Results: There were 0 CFU/cm2 for before and after sanitizing the blocks, therefore, the mean difference was also 0 CFU/cm2. Inferential statistics could not be conducted. Conclusion: The results can be interpreted several ways. One interpretation is that the current toy sanitation frequency at the facility is good. It could also mean that, the methodology used was not able to detect any coliforms. In combination with the conclusions from the different studies discussed in the evidence review, the development of a prescriptive toy sanitation schedule for child care facilities would not be a high priority for health authorities.
Bacterial growth in personal stainless steel water bottles
Authors: Tabaco Adbiel , BCIT School of Health Sciences, Environmental Health  , Heacock Helen , Shaw Fred
Published: September 2020

Background: There is a general understanding and knowledge among reusable personal water bottle users that there are hazards, such as bacterial growth, associated with poor water bottle hygiene practices. Currently, there is no information associated with outbreaks or cases of illness stemming from poor hygiene on personal water bottles. This may be due to lack of awareness that users have become ill from their own water bottle and have failed to report it. Results from previous studies on personal water bottles have indicated that there is a relationship between higher microbiological counts and the interval between cleaning times; the longer water bottles are left unclean, the higher the microbial count. Methods: 29 randomly sampled stainless steel personal water bottles were swabbed at the mouth piece and 1 brand new personal stainless steel bottle was used as a control. Personal water bottle users were provided with an in-person electronic survey at the time of sample collection. The swabs were plated following the 3M Aerobic Plate Count method and incubated for a total of 72 hours. Plates were counted after 24 hours and 72 hours. Results: There was no statistically significant difference between the aerobic bacterial levels (CFU) of personal stainless steel water bottles that were cleaned within one day and those cleaned within a month but more than one day based on the Independent Sample T-test. There was also no statistically significance difference between the aerobic bacterial levels (CFU) of bottles that were rinsed with tap water and those cleaned with soap and water based on the Independent Sample T-test. Conclusion: Based on the results, stainless steel water bottles are not required to be cleaned frequently. It also appears that there is no difference between cleaning with soap and water and just rinsing the bottles with tap water. Despite results showing no statistical difference to support more frequent cleaning and more thorough cleaning practices, these behaviours should be encouraged to prevent and minimize the risk of potential exposure to harmful pathogens.
Evaluating the efficiency of chlorine removal from potable tap water using off-gassing, boiling, and filtration treatment methods
Authors: Wong Katrina , BCIT School of Health Sciences, Environmental Health  , Heacock Helen , Shaw Frederick
Published: September 2020

Background: One of the most frequent complaints to water distribution systems is the taste and odor of chlorine in consumer tap water. Chlorine is a common disinfectant used to inactivate and breakdown microbes and other contaminants. However, excess chlorine can result in an unpalatable chlorinous taste and odor. When water taste becomes too objectionable, consumers may search for alternative water sources, such as raw, untreated water that does not contain chemical additives. Raw, untreated water contains various contaminants, including disease-causing pathogens. To encourage consumers to drink treated tap water, and prevent disease, this study evaluated and compared the effectiveness of off-gassing, boiling and filtration as dechlorination methods for consumers to perform on their tap water. Method: Hach Method 8021 was performed to collect and analyse water samples following treatment with Off-gassing, Boiling and Filtration. Water samples were collected from BCIT SW1-1230. The Hach Pocket Colorimeter ™ II determined the free chlorine concentration of the water samples, and compared to a sample of untreated chlorinated tap water to see which method reduced chlorine concentrations the most. Results: Mean concentration of chlorine following off-gassing was determined to be 0.51 ppm, 0.24 ppm following boiling, and 0.55 ppm following filtration. It was determined that the boiling method was statistically significantly different from the mean values of chlorine concentration from the other two methods, as shown by the Kruskal-wallis test (P=0.000), and therefore was the most effective in dechlorinating tap water samples. This was further confirmed by the Scheffe’s Mutliple-Comparison Test and eyeball test. Conclusion: Based on the results, boiling water is the most effective method to dechlorinate potable tap water for consumer acceptability. The free chlorine levels found post-boiling were also found to be below the WHO’s threshold for tasting and smelling chlorine in drinking water (0.3 ppm), and above WHO’s minimum required 0.2 ppm chlorine residual. Therefore, drinking water following boiling will be safe for consumption, as well as free of chlorinous taste and smell. Public Health professionals can safely advise consumers of an effective method to encourage treated tap water consumption, and to discourage finding alternative water sources.
The evaluation of factors affecting the pre-swim shower behaviors of pool patrons
Authors: Low Andrew , BCIT School of Health Sciences, Environmental Health  , Heacock Helen
Published: September 2020

Background: The hygiene practices of pool patrons are important in maintaining water quality as well as patron health and safety. Poor practices, such as not taking a pre-swim shower, can introduce additional contaminants, which will then react with the free available chlorine to form disinfection by products (DBPs). Not only will excess contaminants decrease the free available chlorine but it will also cause a copious amount of DBPs to be formed. DBPs are known to cause eye and skin irritation, an unpleasant odor, and may cause additional respiratory issues. Therefore, in the interest of public health the number of contaminants introduced into the water should be minimized, which can be done through improving the hygiene practices of patrons. This study investigated factors that may affect pre-swim shower frequencies among aquatic facility patrons. Methods: Data from 78 respondents to a self-administered electronic survey were used in this study. The survey evaluated respondents’ knowledge of pool related illnesses, knowledge of proper aquatic facility hygiene practices and their attitudes toward these practices. Results were analyzed using one-way ANOVA, chi squared test and independent samples t-test. Results: The only statistically significant relationship found was an association between the how often an individual used aquatic facilities and their pre-swim shower frequency; frequent aquatic facility users were found to rarely/never take a pre-swim shower (p = 0.049). As well, factors such as knowledge of pool related illnesses, knowledge of proper hygiene practices, age, and if an individual had read the pool rules were not found to be related to pre-swim shower frequency. Conclusion: The results indicate that educational campaigns aimed at increasing the public knowledge of pool related illnesses and proper pool hygiene practices may not increase pre-swim shower frequencies. Results from this study also indicate that if the showers were cleaner, warmer, and or more private, pre-swim shower frequencies may increase. As well, 79.5% of respondents knew that taking a pre-swim shower is required and 52.6% of participants indicated that they would improve their hygiene practices if consequences were implemented. Taken together, this may suggest that the physical layout of the showering facilities within a swimming pool complex may influence showering behaviour, and greater enforcement of pool rules may be needed in order to increase pre-swim shower frequency.
Evaluation of internal temperature of oysters following standard thermal process recipes
Authors: Leung Johnson , BCIT School of Health Sciences, Environmental Health  , Andraza Chris , McIntyre Lorraine , Heacock Helen
Published: September 2020

Background & Purpose: The seasonal demand for shellfish such as oysters is on the rise. Shellfish are nutritious foods that may be enjoyed in a variety of ways, from slurping raw oysters to cooking oysters by means of boiling, steaming, pan frying and baking. Most consumers of oysters are aware of potential food safety issues with shellfish. Raw or undercooked shellfish can carry bacteria, viruses and toxins, potentially resulting in foodborne illness. Past outbreaks associated with the consumption of raw and undercooked oysters, prompted the British Columbia Centre for Disease Control (BCCDC) to develop guidelines for those preparing, cooking and consuming shellfish. The recommended cooking temperature and time from the guideline was compared with the temperature and time of standard cooking methods from the Fanny Bay Oyster Market restaurant. The purpose of this project was to determine whether standard cooking methods from restaurants attain the guideline’s recommended 90oC for 90 seconds. Method: Four common cooking methods of Oysters were chosen based on recommendation from Chef Chris Andraza and BCCDC researcher Lorraine McIntyre. Oysters were pan fried, deep fried, baked and grilled. Internal temperatures of cooked oysters were then measured with a probe thermometer. Results for each method were analyzed and compared with the standard of 90oC using the one sample t-test from the statistical software package, NCSS11. Results: One sample t-tests showed statistically differences from the deep fried, baked and grilled methods when compared to the standard of 90oC (p = 0.000). The power for all three methods was 100%, therefore there is confidence that the findings reflect the truth. Experimental temperatures were consistently less than the standard. The pan fried method showed no statistically significant difference when compared to the standard of 90oC (p = 135). The power for pan fried method was 29.2%, therefore there is limited confidence that the findings reflect the truth. Therefore the deep fried, baked and grilled methods required additional cooking time to raise internal temperatures of the oysters. Whereas the pan fried method had achieved the standard but further experimentation is required to eliminate the chance of a type II error. Conclusion: It can be concluded that three out of the four cooking methods (deep fried, baked and grilled) can have significantly different mean temperatures. However, different thermal preparation methods prior to final thermal processing requires consideration to determine cooked oyster consumption safety. One out of the four cooking methods (pan fried) attained the standard temperature 90oC. Therefore, it is recommended for deep fried, baked and grilled cooking methods that the cooking time be extended to achieve an internal temperature of 90oC or higher.

Authors: Kwong Adora , BCIT School of Health Sciences, Environmental Health  , Chen Dale
Published: September 2020

Background Electronic e-cigarette ever users has been increasing as of 2015, the most prevalent ever users being young adults aged 20-24 years old. The implication of e-cigarette ever user developing into long term users is a emerging public health concern. Methods Electronic cigarette usage frequency and nicotine consumption was measured through a self-administered online survey of young adults (n= 54). Survey was advertised through social media sites between January 2019 till February 2019. Descriptive and inferential statistic was conducted using NCSS 12 to examine the association between electronic cigarette usage and nicotine consumption. Results Among young adults aged 19 to 24 years old, the frequency of e-cigarette usage was 51% high usage, 31% no usage and 16% medium and low usage. For nicotine consumption, respondents were 25% daily, 40% no use, 18% infrequent, and 14.8% frequent. Conclusion There is an association between more frequent electronic cigarette usage and higher nicotine consumption among young adults in British Columbia. Frequency e-cigarette users were found to consumption nicotine at higher frequency then non users. Further research is needed to fully understand the extent of the relationship of if e-cigarette usage promotes daily nicotine consumption or daily nicotine consumption results in higher e-cigarette usage.
Co-use of cannabis with commonly used licit and illicit drugs
Authors: Maksimovic Aleksandar , BCIT School of Health Sciences, Environmental Health  , Heacock Helen
Published: September 2020

Background: Following the recent legalization of medical cannabis in Canada, and many other countries around the world, people are turning to this drug for both medical and recreational reasons. Naturally, as human’s age, many rely on medication to maintain a better quality of life. Surveys show that, once legal, there will be an increase in cannabis consumption. Many adverse health reactions may occur by concurrently taking cannabis and other medications. Methods: A survey was distributed in-person throughout Vancouver targeting people who do not consume cannabis. The same survey was distributed in Vancouver, but to people coming out of dispensaries, targeting people who do consume cannabis. The survey consisted of seven knowledge questions asking about possible adverse drug interactions occurring between cannabis and commonly used licit and illicit drugs. A chi-square analysis was used to compare knowledge of users and non-users of cannabis. Results: Both users and non-users seemed to be most knowledgeable on the interaction between cannabis and alcohol; 39 out of 57 users (68%) and 23 out of 30 non-users (77%) gave the correct response. As for all the other interactions, neither group was very knowledgeable. The distribution of questions that were answered incorrectly seemed evenly spread between the two groups. The knowledge between users and non-users were significantly different when participants were asked on the possible adverse reactions between cannabis and opioid drugs (p=0.005), and cannabis and sedative drugs (p=0.002). In these cases, cannabis users were more knowledgeable about cannabis interactions than non-users. Conclusion: This study indicates that the general public is not very knowledgeable on the possible adverse reactions that may come about as a result of mixing cannabis and other commonly used licit and illicit drugs. Actions should be taken to provide the public with tools that will aid them in making the right decision when thinking about concurrently using cannabis and other licit and/or illicit drugs.
Efficacy of hand washing beeswax food wrap in household use
Authors: Hsin Celine , BCIT School of Health Sciences, Environmental Health  , Chen Dale
Published: September 2020

Background: Over the years, many reusable products have been invented to replace single-use disposable items to reduce waste. One of such products is the reusable beeswax food wrap, which aims to replace plastic film wraps to store food. According to manufacturer instructions, the beeswax wrap can only be washed with cold water and detergent. This presents the question whether the beeswax wrap can be effectively cleaned, as continuous reuse may present cross contamination issues. This study examines if manufacturer instructions is effective in cleaning the beeswax wrap. Methods: ATP analysis was used to determine the level of cleanliness on the beeswax wrap between the pre-intervention and post-intervention treatments. Pre-intervention samples are the new beeswax wraps. Post- intervention samples are wraps that have been contaminated with avocado, washed, and dried. ATP counts (RLU) were measured with Hygiena SystemSURE Plus ATP monitoring system. Paired T-Test was done on NCSS to analyze the results. Results: The mean of the pre-intervention group was measured at 8 RLU, which is considered clean under the Hygiena standard. The mean for the post-intervention group was measured at 67 RLU, which is considered a fail on cleanliness under the Hygiena standard. This shows that the manufacturer instructions on washing the beeswax wrap does not effectively clean the beeswax wrap. Statistical analysis show p-value is 0.000, therefore one can conclude there is a statistically significance difference in the mean ATP count between pre-intervention and post-intervention beeswax wrap samples. Conclusion: Results show that some food residue remained on the wrap after washing. This means manufacturer instructions cannot effectively clean beeswax wrap. Therefore, it is recommended that manufactures should put a label on their packaging to let their customers know that the wrap can’t be thoroughly cleaned, and certain foods should be avoided for its use. During its use, the wraps should be labeled for the specific category of food it is used for. BCCDC can also use this result to add into the reusable container guideline.
A study of radon concentration in homes in the Sea to Sky corridor and the North Shore of Vancouver British Columbia
Authors: Lu Misha , BCIT School of Health Sciences, Environmental Health  , Chen Dale , Nicol Anne Marie
Published: September 2020

Background: Radon is odourless and colourless gas. It is the second leading cause of lung cancer and can only be found through testing. A radon potential map released in 2012 and highlighted various areas of British Columbia which were high in radon. This study focused on testing for radon gas in houses within the Sea to Sky Corridor and North Shore, areas noted to be high in radon. Methods: This study was conducted by reaching out to participants who lived within these areas. Radon test kits were distributed, and patrons were instructed to keep these kits on the lowest level of the home for at least 91 days. After the 91-day period, the radon test kits were collected and sent to a lab for further results. Results: The lab results were analysed with NCSS Data Analysis software. Three statistical tests were conducted looking at the different areas, types of foundation and if the houses tested are below the recommended average. Two of the two sample T tests were not significant, and the one sample T test came back significant. Conclusion: The two-sample t test (comparison against the two areas) showed that radon did not have equal concentrations. The same can be said with the two sample t tests against foundation types (slab on grade and crawl space). All samples were then compared against the recommend limit set by Health Canada (200 Bq/3), and was concluded that they were all below this limit.
Analysis of lead, arsenic, and cadmium concentrations in instant noodles within the Canadian market
Authors: Katyal Disha , BCIT School of Health Sciences, Environmental Health  , Chen Dale , Kuo Hsin
Published: September 2020

Background: High levels of lead (Pb), arsenic (As), and cadmium (Cd) in instant noodles have been reported in many countries, leading to temporary bans of several popular brands across the globe. There have been no studies analyzing the heavy metal contamination of instant noodles available in Canada to assess the risk for Canadians. As these contaminants are ubiquitous, their presence in food products is inevitable. A diet high in Pb, As, and Cd can cause permanent health conditions and death, as these metals are highly toxic even in small amounts and cannot be metabolized by the body. Methods: 30 packets of instant noodles were purchased from 6 different brands available in Walmart and T&T. Individual packs of noodles, and the accompanying dry seasoning packs, were ground using a blender and stored in sterile Ziplock bags. The samples were processed using an acid digest and then analyzed using ICP-MS/MS. Concentrations of lead, arsenic, and cadmium were measured for a comparison with FDA recommended levels, a cross comparison between wheat and rice noodles, and across all 6 brands. Results: The results show that the levels of Pb, As, and Cd found in instant noodles do not exceed the maximum allowable limits set forth by the FDA and EFSA. A significant difference between rice and wheat noodles is noted for As and Pb concentrations, where rice > wheat (p<0.05). A significant difference between brands is also noted for all three metals (p<0.05). Conclusion: Although the results did not find Pb, As, and Cd concentrations to exceed the recommended levels, the results of this study are inconclusive due to the low power of the analyses. It has been established that rice noodles contain overall higher levels of Pb and As than their wheat counterparts, and the levels vary significantly between different brands. The results indicate a wide window of variability of exposure for Canadians and the low power of the study indicates a larger need for further studies to confirm the findings.
Assessing the knowledge, attitude and practices of hikers on drinking surface water while hiking
Authors: Perrich Leanne , BCIT School of Health Sciences, Environmental Health  , Heacock Helen
Published: September 2020

Background: Hiking is a popular outdoor activity among British Columbians. Within this group of hikers there is bound to be a wide range of knowledge for what is ‘right’ and ‘wrong’ in terms of health and safety practices while hiking. Assessing hiker’s knowledge, attitude and practices regarding drinking water while hiking can help identify whether education for safe drinking water for hikers is needed to aid in the prevention of waterborne illnesses. In addition, potential barriers to hikers treating their water in the wilderness can be determined, with the goal of being able to reduce these barriers in the future. Methods: The survey was created using Survey Monkey and distributed as an online self-administered survey through Facebook and email. The survey contained 18 questions which consisted of demographic and knowledge, attitude, and practice (KAP) questions regarding drinking surface water while hiking. Chi-square statistical tests were used to analyze the data. Results: Of the 328 participants; 72.7% were female, 26.1% male, 0.6% other and 0.6% preferred not to answer. The distribution of age groups was as follows: 31.4% were 19-30 years old, 27.6% were 31-45 years old, 26.4% were 46-60 years old, 14.0% were 61+ years old, and 0.6% preferred not to answer. This study found that the more outdoor knowledge hikers had, the more often they treated surface water used for drinking water (P=0.000), that hiker’s attitude on how risky they thought drinking untreated surface water was affected how often they treated drinking water from surface water sources (P=0.000). The more advanced hikers had more outdoor knowledge (P=0.001), younger hikers thought that drinking untreated surface water was less risky (P=0.025), post-secondary education did not determine how much outdoor knowledge hikers had (P=0.088) and males treated their water less often than females (P = 0.014). Conclusion: This study identified a need for accessible outdoor education with respect to safe drinking water. This education can help hikers make informed decisions to safeguard their health while hiking. This information can be distributed by outdoor organizations, government organizations, high school health education classes, and integrated into outdoor advertisements.

Background In recent years, there have been an increasing number of wildfire events. The effects of global climate change play a big role in the severity and length of these wildfire events. Prolonged periods of wildfire smoke in the air can negatively impact health by causing respiratory distress and exacerbating pre-existing conditions. Many regions have implemented smoke mitigation methods like community clean air shelters, but risk perception can influence whether or not these methods are effectively used. The purpose of this study is to evaluate the risk perception of residents in British Columbia regarding wildfire smoke inhalation and smoke mitigation methods. Methods A survey was distributed to residents living in British Columbia to evaluate their risk perception of wildfire smoke and use of smoke mitigation methods. The online survey was created with Survey Monkey, distributed via Facebook, Twitter, and Reddit, and took approximately five minutes to complete. The results were collected in Microsoft Excel and analyzed with NCSS statistical software. Results Chi-square tests showed a significant association between gender and the risk perception of inhaling wildfire smoke, exercising outdoors during a smoke event, going outside during an air quality advisory, and the decision to find a clean air space during a smoke event. There were some associations with age and geographical region as well. Results showed that most people practice some form of smoke mitigation, such as staying indoors, seeking refuge in a clean air space, and using masks and/or portable air filters. Conclusions Based on the results, gender has a significant impact on risk perception of wildfire smoke inhalation. Other demographics, such as age, geographical region, education, and ethnicity, did not display many significant associations. This study also identified that participants may have conflicting views about the protectiveness of a surgical/cloth mask during a smoke event. Most participants practiced some form of smoke mitigation method, like staying indoors.

Background: Environmental Health Officers (EHOs) are responsible for assessing the risk that food establishments pose to the public through regular inspections. The results of these inspections are then posted online for the public to view in British Columbia (BC). However, cities such as Toronto and New York City, have adopted the use of placards that are visibly placed at each food establishment, as well as posting the results online. The purpose of the placards is to provide a quick method for the public to ascertain the safety of food establishments. The use of placards has been shown to increase the compliance of food operators, as well as play a role in reducing foodborne illnesses. The purpose of this study was to determine if British Columbians would like to have the results of health inspections displayed on a placard in food establishments, in addition to them being posted online. Methods: An online, self-administered survey was created on SurveyMonkey Canada and distributed to residents of BC through Facebook and Reddit. The survey took approximately five minutes to complete and responses were collected over a nine-day period. The data was then analyzed using NCSS software. Results: From the 176 respondents, it was determined that approximately 44% of people knew about health inspection reports being posted online in BC, however, only 33% of people have visited health authority websites to view the inspections. 93% of the respondents would like to see a placard system implemented in BC. Furthermore, 72% of respondents would like to see a letter grade ranking of placards as opposed to a more general “Pass”, Conditional Pass” or “Closed” system. Results indicated a statistically significant association between the desire for a placard system and selecting a restaurant to eat at (p=0.000). Whether or not one views an online inspection report had no bearing on whether a placard system was desired. (p = 0.231). There is no association between age of BC residents and the preference for placards in BC (p = 0.618). However, there was an association between the age of respondents and knowledge of online reports of health inspections (p = 0.008), indicating that younger people are less likely to know about online health inspections that older populations. Conclusion: The results of this research study indicated that residents of BC overwhelmingly support the use of placards. BC residents would also like to see a letter grade placard system implemented. Although BC residents would like to see placards in food establishments, further research is required to assess what food operators, as well as other EHOs, think about implementing a placard system in place in food establishments.
