Authors: Ahmed Md Sultan , Ali Sardar Md Mohsin , Ahmad Masum , Kabir Kamal Humayun 
Published: September 2021

The samples of the cauliflowers were analyzed to assess the residue level of six insecticides (i.e.; cypermethrin, quinalphos, diazinon, malathion, fenitrothion and acephate) using GC-FTD and GC-ECD method. Out of analyzed 75 collected samples of cauliflower from farmer’s field of Jessore, Gazipur and Rangpur, 38.67% (29 from 75) were found to be contaminated with the insecticides. Many samples contained cypermethrin, acephate and fenitrothion residues. Quinalphos, acephate and fenitrothion were found as multiple product residues representing 13.79% (4 from 29) of the total contaminated samples and the rest 86.21% contained single insecticide residue. About 13.33% (10 of 75) of the total samples had residues exceeding the MRL (Maximum Residue Limit) irrespective of single or multiple insecticide residues. Malathion residue was found only in one sample from Jessore. Two samples showed diazinon residue one from Jessore and the other one from Rangpur location. The detected residue levels of both malathion and diazinon were below the MRL, which might be due to higher rate of degradation. The presence of highest residue levels of insecticides in cauliflowers may be due to its irrational and repeated use before harvest.

The objectives of this study were to assess the bacteriological quality of tap water samples obtained from different markets of different upazillas of Mymensingh, Sherpur & Gazipur district. For achieving the above mentioned objectives, methods of heterotrophic plate count (HPC) and total coliform count (TCC) were applied. Moreover, isolated E. coli from tap water samples were characterized by using biochemical test, molecular method and antimicrobial susceptibility tests. HPC was highest in market tap water collected from Kaligonj and TCC was highest in market tap water of collected from Mymensingh sadar. The geometric mean of HPC of Mymensingh, Gazipur and Sherpur districts water was 8.4x105, 2.5 x106 and 6.8 x105 C.F.U/100 ml. All isolates of E. coli (n=20) were amplified by using 16S rRNA gene based PCR. In respect to antimicrobial susceptibility testing, most of the E. coli isolates were susceptible to norfloxacin, ampicilin, tetracycline, streptomycin and ciprofloxacin. Furthermore, a few E. coli isolates were intermediate resistant to gentamycin and ciprofloxacin. However, a few of the E. coli isolates were resistant to erythromycin and amoxycilin. Moreover, out of 20 E. coli isolates 3 (15%) isolates were detected as multidrug resistant. This study indicated the presence of multidrug resistant E. coli isolates in tap water in Mymensingh, Sherpur and Gazipur districts that warrants particular attention.

Published: September 2021

Street food vending has become an important public health issue and a great concern to everybody. This is due to widespread food borne diseases, due to the mushrooming of wayside food vendors who lack an adequate understanding of the basic food safety issues. Major sources contributing to microbial contamination are the place of preparation, utensils for cooking and serving, raw materials, time and temperature abuse of cooked foods and the personal hygiene of vendors. The objective of the study was to explore the microbiological quality of different street food; Chotpoti, Chanachur, Amra (Spondias mombin) and Jolpai (Elaeocarpus serratus (Veralu / Ceylon Olive) sold by various street vendor at Khulna city, Bangladesh. A total of 20 samples were collected randomly from street vendors and tested for the presence of bacteria following standard microbiological method used for isolation, enumaration and identification of bacreria. All the examined samples were contaminated by various types of bacteria. The total viable count (TVC) in different street food samples was ranged from 9.6 x 10 CFU/g to 5.9x10 CFU/g. Among samples Escherichia coli 8(40%), Staphylococcus spp. 5(25%), Klebsiella spp. 4(20%), Salmonella spp. 1(5%) and Shigella spp. 2 (10%) were isolated. Escherichia coli were found highest 3(50%) Jolpai samples, then another organisms Staphylococcus spp. was found highest 2(50%) in Chotpoti and then Klebsiella spp. was found one in each sample. Therefore, application of sound risk analysis policies is being advocated to provide a scientific base to the host of risk management option which Bangladesh may need to explore to ensure public health and safety.

This study aimed to investigate the prevalence and associated factors of childhood diarrhea among under-five children in Southern coastal area of Bangladesh. A community-based cross-sectional study conducted from April to June 2018 among 202 randomly selected children. A structured questionnaire used to collect information on a three month diseases occurrence and other covariates. The association of diarrhea with socio economy, personal and food hygiene practices observed using multivariate logistic regression after adjusting for potential confounders. Prevalence of childhood diarrhea was 10.9%. In bivariate analysis, mother’s education, family income, father’s occupation, hand washing of child before feeding and refrigerator associated with outcomes. In multivariate analysis, father’s occupation, hand washing of child by soap before feeding and having refrigerator in households was associated with childhood diarrhea after controlling the socio-demographic factors (age and gender). Child of unemployed fathers were more likely to have diarrhea than employed father (AOR=0.206; 95% CI: 0.070-0.610).Child do not wash hand before feeding (AOR=0.393; 95% CI =0.102-0.511) and households not having refrigerator (AOR= 0.072; 95% CI: 0.007-0.745) had higher odds of diarrhea. The load of diarrhea in this setting was almost double to the national rate. Poor hand washing of child and refrigerator are major risk factor high burden of the disease. Health promotion strategies on proper food storage and child feeding practices are recommended for the prevention of childhood diarrhea.

Published: September 2021

The present study was made to detect the amount of residue degradation rate of insecticides in cauliflower under supervised field trial. Six field trials were carried out sprayed with recommended dose of acephate (2 g/L of water), cypermethrin (1 ml/L of water) and diazinon, malathion, quinalphos and fenitrothion (2 ml/L of water of each), respectively. Samples were collected at 0, 1, 3, 5, 7, 10 and 15 days after spray (DAS). The degradation rate of cypermethrin, diazinon, quinalphos and fenitrothion were detected up to 10 days after spray (DAS) in cauliflower, while malathion and acephate could be detected at 5 and 15 DAS respectively. The detected quantities were above Maximum Residue Limit (MRL) up to 7 DAS for quinalphos, Fenitrothion and acephate, 5 DAS for diazinon and cypermethrin and 3 DAS for malathion. Malathion degraded quickly and acephate degraded slowly as compared to other tested insecticides. Therefore, malathion might be use for cauliflower cultivation having waiting period of 5 DAS and incase of diazinon and cypermethrin it was 7 DAS. Quinalphos, fenitrothion and acehate had higher waiting period of 10 DAS which might be due to slower rate of degradation.

Published: September 2021

An experiment was carried out to comparative analysis of nutritional quality of different fish feed from different feed dealers and industries in greater Noakhali region and to compare the values with those provided by the manufacturers. The feed samples were collected from different feed industries and dealer's shop of these region. Feed samples were collected during 10 August to 5 September, 2016. The collected feed samples were stored and analyzed in the Fish Nutrition Laboratory of the Department of Aquaculture in the Faculty of Fisheries, Bangladesh Agricultural University (BAU), Mymensingh for proximate composition (moisture, ash, crude protein, crude lipid, crude fiber, carbohydrate) following standard methods. Results showed that there was significant variation between analyzed and company provided nutritive values of different feeds. Some feed samples have low moisture level (difference 0.7 to 3.3%). Ash content of the experimental samples also show a variety of results compared to their labeled composition. Only some feed have more values to the company provided values, such as, Mega starter (12.13%) and Bengal grower (12.75) proportion with 12%. Some feed contains more difference range of 6.01% more than labeled values is RP feed (20.01%). Maximum feed samples had lower crude protein (difference 0.05 to 4.65%) than the company provided protein values. However, only crude protein of Bengal finisher (29.95%) and Aftab grower (28.07%) feeds were found to be almost same to the company provided nutritive values (30% and 28%). The lipid, ash and carbohydrates contents of the experimental samples also have a difference range. The highest lipid values are available in Provita starter (9.76%) and lowest values containing feed Setu grower (4.33%). The highest carbohydrates content in the feed Provita starter (36.84%). The findings of this study demonstrated that low quality commercial fish feeds were supplied to the fish farmers by majority of feed companies. Therefore, the study will generate some information to the farmers which will help to choose the best feed for their aquaculture production.
