What are anticipated health effects associated with this problem? (i.e., consumption of the product 

and/or specific ingredients) Include narrative and please describe severity. Explain and cite literature references when 

applicable. 

In the United States, an estimated 1.2 million people are infected with nontyphoidal Salmonella 

annually. Salmonella enterica serotype Newport (Salmonella Newport) is the third most common 

Salmonella serotype causing human salmonellosis infections in the United States (1). Foodborne 

outbreak investigations associated with Salmonella Newport have implicated multiple types of 

foods, including seeded vegetables (for example, tomatoes and cucumbers), beef, fruits, pork, 

poultry, sprouts, dairy and root vegetables (for example, onions). As of August 6, 2020, a total of 

640 people infected with the outbreak strain of Salmonella Newport have been reported from 43 

states. (https://www.cdc.gov/salmonella/newport-07-20/index.html) 

The most common clinical illness caused by nontyphoidal Salmonella infection is gastroenteritis (2, 

3). Nausea, vomiting, abdominal cramps begin 6 to 72 hours after ingestion of contaminated food or 

water. Salmonella gastroenteritis usually is a self-limited disease in a normal host. Although a study 

of Salmonella Newport outbreaks reported that children <5 years of age had the highest annual 

incidence of gastroenteritis (7.6 per 100,000), 27% of cases affected by gastroenteritis in the study 

were adults 20-49 years of age and 29% of cases were adults ≥50 years (1). Some patients, 

particularly those with impaired immunity, may develop chronic diarrhea after an acute episode. 

Patients from developed countries typically do not develop dysentery from salmonellosis, typified by 

bloody stools, fever, headaches and malaise. However, newborns with Salmonella infections may 

develop fever and blood stools. 

Salmonella Newport is one of the Salmonella serotypes that have a propensity to invade the 

bloodstream, causing bacteremia and extraintestinal focal infections (3). Symptoms of salmonellosis 

bacteremia are fever, chills, sweating, myalgias and weight loss that may last for days or even 

weeks. Those at risk for invasive salmonellosis include neonates, infants, adults ≥ 65 years, patients

with impaired immunity or immunosuppressing treatments, individuals with decreased gastric pH 

activity (from medications or surgery) and patients with parasite infections (for example, malaria or 

schistosomiasis) (3, 4). Children with sickle cell anemia are also at high risk of Salmonella 

bacteremia and osteomyelitis, an extraintestinal infection. 

Focal extraintestinal infections may occur anywhere: brain (meningitis, brain abscess), 

cardiovascular system (endocarditis, aneurysms), and bones/joints (osteomyelitis, septic arthritis), 

etc.(2-4). Extraintestinal infections are difficult to cure and usually requires prolonged antimicrobial 

treatment and surgical debridement. Salmonella Newport infection is associated with meningitis. 

Neonates and infants < 4 months of age are at highest risk. Even with antibiotic treatment, 10% of 

patients with meningitis from salmonellosis die (3). 

This outbreak includes raw onions and ready-to-eat food products with onions. Salmonella species 

(spp) can survive refrigeration and remain viable at room temperatures or reduced temperatures for 

weeks (1, 3). Individuals eating raw onions and RTE food products with onions are at reasonable 

risk of contracting salmonellosis. Onions and other food products in this recall can be eaten after 

cooking or heating, but individuals who do not cook or heat onions adequately at high enough 

temperatures and time periods are at risk of contracting salmonellosis. Salmonella can survive 

cooking times for less than 12 minutes at less 60 degrees Celsius (▪ C) or 140 degrees Fahrenheit 

Page 4 of 8 
 

 

 

 

 

 

(

▪

F). Cooking food at 54.4▪ C or 130 ▪F for 1 hour or 60 ▪ C or 140 ▪F for at least 15 minutes can kill 

Salmonella spp. 

Many recipes call for onions to be cut with knives on boards, mixed with other foods, like salad 

greens. Onions may be stored in containers with other onions or food products. There is a reasonable 

probability that contaminated onions can contaminate food surfaces, such as cutting boards and 

utensils (2). Cooked or raw food that had contact with contaminated onions or food surfaces may 

also become contaminated. Studies have suggested that infants in shopping carts contaminated with 

Salmonella from meat or poultry are at risk of contracting salmonellosis (2, 3).Thus, individuals who 

touch contaminated food surfaces or ingest food that had contact with contaminated surfaces with 

their hands can become infected with salmonellosis if unwashed fingers touch their mouths.

item is selected below, specify the corresponding health hazard.) 

☐Highly likely to occur (every time the product is used) 

☒Likely to occur (reasonable probability of occurrence) 

☒Might occur (remote probability of occurrence) 

☐Unlikely to occur 

☐Unknown (please explain): 

☐Not applicable 

Conclusion: 

Raw onions, ready-to-eat food products with onions: Normal hosts who had eaten raw contaminated 

onions or RTE food products with contaminated onions or who had contact with food surfaces/utensils 

contaminated from raw onions and RTE food products are at reasonable risk of contracting a self-limited 

gastroenteritis. 

High-risk individuals (see part 8) who ingest raw onions or RTE food products with contaminated 

onions or had contact with food surfaces contaminated by such products are at reasonable risk for severe 

gastroenteritis or invasive salmonellosis (bacteremia, extraintestinal infections). 

Page 6 of 8 
 

Cooked onions or food products that need to be cooked or heated: There is a remote probability that 

cooked onions or food products that need cooking or heating prior to consumption may not be 

adequately heated at high enough temperatures for an adequate time period to kill Salmonella. Thus, 

normal hosts who had ingested these food products may be at remote risk of contracting gastroenteritis, 

while at-risk individuals are are at remote risk of contracting invasive salmonellosis or severe 

gastroenteritis.

ABSTRACT 

On 7/13/20, after receiving notification from PulseNet, FDA CORE Signals began

evaluating a cluster of 134 Salmonella Newport illnesses from 16 states [CA (3), IA

(3), IL (1), MI (13), MN (3), MO (2), MT (11), NC (3), OH (5), OR (42), SD (8), TN (1), UT 

(28), WA (1), WI (1), WY (9)]. Canadian health authorities reported one clinical isolate

matching the genetic sequence of this cluster. At the time of transfer, epidemiologic

information was unable to identify a single suspect vehicle. Vehicles of interest 

included: tomatoes, cilantro, onions, and peppers. The traceback investigation was

narrowed to red onions based on the findings of the Canadian outbreak investigation

which identified red onions from Thomson International Inc. (Bakersfield, CA) as the 

likely source of Canadian illnesses. FDA’s traceback investigation identified Thomson 

(b) (4)

International Inc. (Bakersfield, CA) as the source of red onions US POS where ill 

people reported exposure prior to becoming ill. On 8/1/20, Thomson International Inc.

(Bakersfield, CA) initiated a recall of red, yellow, white, and sweet yellow onions. A 

total of 113 samples were collected by FDA during investigations at Thomson

International, Inc (Bakersfield, CA) or targeted sampling at distribution centers. Ten 

samples (4 sediment, 1 scat and 5 ultrafiltration water samples) were reported

positive for Salmonella but did not match the outbreak strain. The vehicle for this 

outbreak was confirmed as red onions based on the epidemiologic and traceback

evidence. At the conclusion of the CORE Response phase, a total of 1132 cases in 48

states [AK (25), AL (2), AR (2), AZ (39), CA (128), CO (32), CT (2), DE (2), FL (8), GA

(11), HI (3), ID (43), IL (54), IN (4), IA (31), KS (3), KY (3), ME (6), MA (2), MD (7), MI

(47), MN (19), MO (11), MS (5), MT (72), NC (6), ND (9), NE (10), NH (1), NJ (12), NM

(3), NV (14), NY (14), OH (11), OK (1), OR (110), PA (27), RI (3), SC (1), SD (24), TN

(7), TX (2), UT (115), VA (10), WA (150), WI (11), WV (3), WY (27)] and 515 Canadian

cases in 7 Canadian provinces were associated with this outbreak. 

SIGNALS AND SURVEILLANCE ACTIVITIES 

On 7/10/20, PulseNet users were notified of a national cluster of Salmonella Newport

illnesses, that were genetically related to historical almond isolates and a historical

Newport cluster. On 7/13/20, CORE Signals and CDC discussed the emerging outbreak

and the cluster’s relationship to historical isolates. The cluster rapidly expanded and

at the time of transfer on 7/21/20, there were 134 cases across 16 states: CA (3), IA

(3), IL (1), MI (13), MN (3), MO (2), MT (11), NC (3), OH (5), OR (42), SD (8), TN (1), UT 

(28), WA (1), WI (1), WY (9). Most illnesses were geographically focused within the

central, midwestern, and western states. Isolation dates ranged from 6/20/20 to 

7/11/20, and available onset dates (n=42) ranged from 6/19/20 to 7/7/20. The cases 

ranged in age from 2 to 92 (median = 40) years, and 55% of cases were female.

Twenty-four cases were hospitalized, and there were no deaths. At the time of 

transfer, the outbreak was considered to be ongoing and was expected to expand

due to a 16-day lag time (the time between illness onset and laboratory

confirmation). 

The genetic sequences of the cluster isolates for the outbreak cluster 2007MLJJP-1

were considered highly related by 0-4 alleles and 0-6 SNPs. Additionally, Canadian

health authorities reported one clinical isolate matching the genetic sequence of this

cluster. Of historical note, the isolates for outbreak cluster 2007MLJJP-1 were within 

five alleles or 11 SNPs of isolates from the outbreak cluster, 1509MLJJP-1, which 

closed without an identified vehicle. In addition, NCBI’s Pathogen Detection Pipeline

identified historical clinical isolates from the United Kingdom as well as CA almonds

(raw almond samples collected in 2016 and 2017) that were within 14 SNPs from this

cluster. The nut samples were collected under a blinded sampling assignment with a

contract laboratory and the associated firm and branding information were not

available. 

CDC hosted States calls on 7/15/20 and 7/20/20 and cases reported multiple common

exposures including, fresh produce (tomatoes, cilantro, onions, and leafy greens),

eggs, cheese, beef, chicken, and pork. Tree nuts were rarely reported (3/25 cases).

State investigators decided to interview a select few existing and new cases with a

modified National Hypothesis Generating Questionnaire (NHGQ). The only food items 

that were significant (α =0.05) when compared to the FoodNet Population Survey

were cilantro and leafy greens. Cases across several states reported consuming foods

from Mexican-style and sandwich-style restaurants. Nationally, 6 cases reported

Subway, 3 reported Jersey Mike’s, and 2 reported Jimmy John’s. Many state partners 

reported an increase and/or backlog of Salmonella Newport or Salmonella isolates 

pending further characterization in their laboratories. 

Eight restaurant and facility subclusters were identified in CA and OR. 

 The California Department of Public Health investigated 5 Mexican-style

restaurant sub-clusters all located in the Northern CA region and all part of a

larger Salmonella serogroup C outbreak investigation. The 5 subcluster locations 

and their subcluster identifications are listed below. At the time of transfer, most 

illness isolates were pending WGS, therefore it was unknown if these illnesses

were related by WGS or epi-linked to the Newport cluster, 2007MLJJP-1. Two 

2007MLJJP-1 cluster isolates, CA___M20X01046 and CA___M20X01079, were 

associated with CA subcluster 1 and 2, respectively. The remaining isolates

associated with the CA clusters were not sequenced by the time of transfer. All 

serogroup C outbreak cases were residents of Northern CA and most were from

the San Francisco Bay area. Most cases reported consuming fresh produce as part

of their meal or as an ingredient in salsa and pico de gallo. Identified meal dates 

ranged from 6/16/20 to 7/7/20. State investigators requested the restaurants to

Epidemiology

A case was defined as a person with infection with Salmonella Newport with an isolate

matching by cgMLST within 0-6 alleles and an illness onset on or after 6/15/20.This

outbreak included 1132 cases from 48 states [AK (25), AL (2), AR (2), AZ (39), CA

(128), CO (32), CT (2), DE (2), FL (8), GA (11), HI (3), ID (43), IL (54), IN (4), IA (31), KS

(3), KY (3), ME (6), MA (2), MD (7), MI (47), MN (19), MO (11), MS (5), MT (72), NC (6),

ND (9), NE (10), NH (1), NJ (12), NM (3), NV (14), NY (14), OH (11), OK (1), OR (110),

PA (27), RI (3), SC (1), SD (24), TN (7), TX (2), UT (115), VA (10), WA (150), WI (11),

WV (3), WY (27)]. Isolation dates ranged from 6/20/20 to 9/14/20, while confirmed

reported onset dates ranged from 6/19/20 to 9/11/20. Ages ranged from 5 days to

102 years (median 41), and 58% of cases were female. Of the cases with information 

available, 167/705 (24%) were hospitalized, and there were no reported deaths. All 

isolates were closely related to each other at 0-6 alleles by cgMLST. 

There were early signals for Mexican-style foods. Canada identified clinical cases 

caused by the same strain and noted red onions as a leading hypothesis in their

investigation. Based on Canada’s findings and preliminary review of traceback

records, red onions were identified as the suspect vehicle. 

From 380 returned questionnaires for the US outbreak, 344 (91%) ill people reported

consuming onions or meals that likely contained onions. Of which, 66% of cases

reported consuming red onions, or meals that likely contained red onions, 62%

reported white onions, and 53% yellow onions. Some cases reported eating multiple 

onion varieties. 

CDC closed this investigation as of 10/2/2020 with red onions as the confirmed

vehicle of this outbreak. 

The Public Health Agency of Canada declared the Canadian outbreak over on 9/25/20.

At closeout, there were 515 confirmed cases of Salmonella Newport linked to this

outbreak in the following provinces: British Columbia (121), Alberta (293),

Saskatchewan (35), Manitoba (26), Ontario (14), Quebec (25) and Prince Edward

Island (1). Seventy-nine of 419 individuals (79%) with information available were

hospitalized. Three people died (deaths not attributed to Salmonella). Illnesses 

occurred between 6/15/20 (onset) to 8/28/20 (specimen collection date). 

The CDC linelist and WGS tree are available on EON # 432687.

Sysco Distribution Centers. Fifty-one samples were collected from investigations

at Thomson International Inc facility and fields in Bakersfield, CA and Holtville, CA

were collected. Of the total 113 samples collected, ten samples were reported 

positive for Salmonella but did not match the outbreak strain. Thomson International 

Inc. Bakersfield, CA) initiated a recall of red, white, yellow and sweet yellow onions on

8/1/20. Based on the epidemiologic and traceback evidence, red onions were

confirmed as the vehicle of this Salmonella Newport outbreak. 

As of 10/5/20, a total of 1132 illnesses were reported from 48 states, including 167

hospitalizations. A traceback investigation identified Thomson International Inc.

(Bakersfield, CA) as the source of red onions to ten US POS where ill people reported

EON-432687 - 07/21/2020 

Salmonella Newport (2007MLJJP-1)/ Unknown/ Jul 

2020 Date(s): 

Type of Incident: CORE Signals Product Centers: CFSAN Qualifier: Foodborne Illness 

Districts Involved: RRT Involved: Notification Source: CDC 

Description 

On 7/10/2020, CDC notified PulseNet users of a national cluster of Salmonella Newport illnesses. The cluster 

has rapidly expanded and as of 7/21/2020, there are 134 cases across 16 states: CA (3), IA (3), IL (1), MI (13), 

MN (3), MO (2), MT (11), NC (3), OH (5), OR (42), SD (8), TN (1), UT (28), WA (1), WI (1), WY (9). Most 

illnesses are geographically focused in the central, midwestern, and western states; however, recently illnesses 

have been identified in southeast states of NC and TN. Isolation dates range from 6/20/2020 to 7/11/2020 and 

onset dates (n=42) range from 6/19/2020 to 7/7/2020. The lag time is 16 days and the outbreak is considered 

ongoing. The cases range in age from two to 92 years, with a median age of 40 years and 55% of cases are 

female. There have been 24 hospitalizations and no deaths. Seven of 68 cases have self-identified as having 

Hispanic/Latino ethnicity. 

Isolates from all cases are highly related to each other and are within 0-4 alleles and 0-6 SNPs. Additionally, 

Canada health authorities report one clinical isolate matching the genetic sequence of this cluster. This cluster 

is related by five alleles or 11 SNPs to isolates from the historical cluster 1509MLJJP-1, which closed without 

an identified vehicle. NCBI's Pathogen Detection Pipeline identified historical clinical isolates from the United 

Kingdom and CA almond isolates (raw almond samples collected in 2016 and 2017) are related within 14 

SNPs from this cluster. The nut samples were collected under a blinded sampling assignment with a contract 

laboratory. 

CDC hosted States Calls on 7/15 and 7/20 and cases reported multiple common exposures including, fresh 

produce (tomatoes, cilantro, onions, and leafy greens), eggs, cheese, beef, chicken, and pork. Tree nuts were 

rarely reported (three of 25 cases). State investigators decided to interview a select few existing and new cases 

with a modified National Hypothesis Generating Questionnaire (NHGQ). The only food items that were 

significant (a =0.05) when compared to the FoodNet Population Survey were cilantro and leafy greens. Cases 

across several states reported consuming foods from Mexican-style and sandwich-style restaurants. Nationally, 

6 cases reported Subway, 3 reported Jersey Mike's, and two reported Jimmy John's. 

Eight restaurant and facility subclusters have been identified in CA and OR. 

The California Department of Public Health is investigating five Mexican-style restaurant sub-clusters all in 

the Northern CA region and all part of a larger Salmonella serogroup C outbreak investigation. This 

investigation involves 38 cases and 35 cases are pending WGS sequencing (so at this time, it is unknown if 

these are related by WGS or epi-linked to the larger Newport cluster 2007MLJJP-1). All CA cases in this 

cluster are from northern CA and most are in the San Francisco Bay area. An additional 10 Salmonella 

illnesses from Central and Southern California have not been added to this cluster. Most cases reported 

consuming fresh produce as part of their meal or as an ingredient in salsa and pico de gallo. State investigators 

have requested the restaurants provide lists of ingredients (including dried spices and seasonings) used to make 

pico de gallo, salsas, and guacamole. Invoices for produce (including cilantro and tomatoes) have been 

requested for all restaurants. Cilantro and tomatoes are items of greatest interest for their state investigation. 

Oregon Health Authority is investigating 3 sub-clusters; 2 are associated with restaurants (Mexican-style and 

Subway) and the 3th is associated with an assisted living center. 

Sub-clusters identified in the Salmonella Newport (2007MLJJP-1) investigation.

EON-432687 - 07/21/2020 

No single suspect vehicle has been identified; however, CDC believes the vehicle is likely an FDA-regulated 

food product and may possibly be tomatoes, cilantro, onions, or peppers. Supplier review and traceback efforts 

may be able to aid the investigation by identifying common suppliers and narrowing down the items of interest. 

CDC will be issuing an investigational notice about this investigation. 

On Tuesday, 7/21/2020, CORE Signals transferred this incident to CORE Response Team 3 based on the 

following rationale: 

1) This is a rapidly expanding multi-state outbreak likely associated with a FDA-regulated product; items of 

greatest interest include tomatoes, cilantro, onions, or peppers. 

2) Response coordination for traceback, sampling, product and firm actions, and communication is needed

Salmonella Newport/Red Onion/ Jul 2020 Date(s): 

Type of Incident: CORE Signals Product Centers: CFSAN Qualifier: Foodborne Illness 

Districts Involved: LOS-DO, SAN-DORRT Involved: Notification Source: CDC 

Description 

On 7/13/20, after receiving notification from PulseNet, FDA CORE Signals began evaluating a cluster of 134 

Salmonella Newport illnesses from 16 states [CA (3), IA (3), IL (1), MI (13), MN (3), MO (2), MT (11), NC 

(3), OH (5), OR (42), SD (8), TN (1), UT (28), WA (1), WI (1), WY (9)]. Canadian health authorities reported 

one clinical isolate matching the genetic sequence of this cluster. At the time of transfer, epidemiologic 

information was unable to identify a single suspect vehicle. Vehicles of interest included: tomatoes, cilantro, 

onions, and peppers. The traceback investigation was narrowed to red onions based on the findings of the 

Canadian outbreak investigation which identified red onions from Thomson International Inc. (Bakersfield, 

CA) as the likely source of Canadian illnesses. FDA's traceback investigation identified Thomson International 

Inc. (Bakersfield, CA) as the source of red onions US POS where ill people reported exposure prior to 

becoming ill. On 8/1/20, Thomson International Inc. (Bakersfield, CA) initiated a recall of red, yellow, white, 

and sweet yellow onions produced by Thomson International. A total of 113 samples were collected by FDA 

during investigations at Thomson International, Inc (Bakersfield, CA) or targeted sampling at distribution 

centers. Ten samples (4 sediment, 1 scat and 5 ultrafiltration water samples) were reported positive for 

Salmonella but did not match the outbreak strain. The vehicle for this outbreak was confirmed as red onions 

based on the epidemiologic and traceback evidence. At the conclusion of the CORE Response phase, a total of 

1132 cases in 48 states [AK (25), AL (2), AR (2), AZ (39), CA (128), CO (32), CT (2), DE (2), FL (8), GA 

(11), HI (3), ID (43), IL (54), IN (4), IA (31), KS (3), KY (3), ME (6), MA (2), MD (7), MI (47), MN (19),

General Situational Awareness 

On 7/10/2020, CDC notified PulseNet users of a national cluster of Salmonella Newport illnesses. The cluster has rapidly expanded and as of 7/23/2020, there are 242 

cases across 33 states: AK, AZ, CA, IA, ID, IL, IN, MI, MN, MO, MT, NC, ND, NE, NY, OH, OR, SD, TN, UT, VA, WA, WI, WY. Isolation dates range from 6/20/2020 to 

7/11/2020 and onset dates range from 6/19/2020 to 7/7/2020. The cases range in age from two to 92 years, with a median age of 40 years and 55% of cases are female. 

There have been 29 hospitalizations and no deaths. Isolates from all cases are highly related to each other and are within 0-4 alleles and 0-6 SNPs. Additionally, as of 

7/23/20, Canada health authorities report six clinical isolates match the genetic sequence of this cluster and red onions are their leading suspect vehicle. NCBI’s Pathogen 

Detection Pipeline identified historical clinical isolates from the United Kingdom and CA almond isolates (raw almond samples collected in 2016 and 2017) are related 

within 14 SNPs from this cluster. Cases across several states reported consuming foods from Mexican-style and sandwich-style restaurants including Subway. No single 

suspect vehicle has been identified; however, based on reported food exposures, vehicles of interest include tomatoes, cilantro, onions, or peppers. CDC issued an 

Investigation Notice regarding this incident on 7/21/20. CDC is not recommending that consumers avoid any particular food at this time. 

Operational Period 1 

On 7/24/20, CORE issued an assignment to ORA HAF1E (NWE-DO) for traceback data from Subway Company 

(b) (4)

). The requested documents were received on 

7/30/20. CDC issued a case count update and the Public Health Agency of Canada issued a Public Health Notice regarding this outbreak on 7/24/20. On 7/27/20, CORE 

issued an assignment (eNSpect Assignment #167287) to ORA HAF3W (DAL-DO) for record collection at Sysco 

(b) (4)

Related 

records were received on 7/29-7/30/20. CORE issued an assignment (eNSpect Assignment #167509) to ORA HAF4W (DEN-DO) for record collection at Onions 52 Inc 

(Syracuse, UT) related to the Canadian traceback investigation. Records were received on 7/29/20. Based on preliminary record review, a majority of Sysco locations 

included in the US traceback investigation received onions from Onions 52. On 7/28/20, CORE requested record collection by ORA HAF6W (SEA-DO) from

 the requested documents were received on 7/28/20. A firm call was held with Sysco

discuss the outbreak, public communication and product actions. Public Health Agency of Canada and the Canadian Food Inspection Agency issued a Public Health 

suspect vehicle for this outbreak. On 7/31/20, CDC reported 508 cases and PHAC reported 114 cases. Additionally, an Industry call was held to inform the industry of 

Notice and recall notice to the outbreak and Sysco 

(b) (4)

recall on 7/30/20. As of 7/30/20, FDA and CDC declared red onions as the 

public communications. 

Operational Period 2 

On 7/31/20, FDA and CDC issued web posts regarding this outbreak naming Thomson International Inc (Bakersfield, CA) as the likely source. Thomson International Inc. 

initiated their recall and issued a press release on 8/1/20. Red, yellow, white, and sweet yellow onions produced by Thomson International and shipped from 5/1/20 

through 8/1/20 were subject to recall. The Canadian Food Inspection Agency issued a recall notice for the Thomson International Inc. recall on 8/1/20. The Public Health 

Agency of Canada issued an updated Public Health Notice on 8/2/20. CORE issued an assignment (FACTS #12055268) to ORA HAF5W for an inspection including 

record collection and product and environmental sampling at Thomson International and an assignment (FACTS #12055297) to ORA OHAFO Domestic Produce Safety 

Branch for a root cause investigation, farm investigation and water sampling at Thomson International Inc. on 8/2/20FDA and CDC issued updated web posts to include 

information about the Thomson International Inc recall on 8/3/20. On 8/3/20, FDA provided written responses to 

(b) (4)

 regarding traceback investigation questions. 

ORA HAF5W and the California Department of Food and Agriculture (CDFA) began the inspection at Thomson International on 8/3/20. In total, ORA HAF5W collected 

three environmental (#1145759, 1145760, 1145761), and one scat sample (#1141449). Sample #1145759 and #1145760 were reported negative on 8/6/20 and 8/7/20 

respectively. ORA HAF5W completed their investigation and ORA PSN, ORA HAF5W, California Department of Public Health and the California Department of Food and 

Agriculture began a root cause investigation at Thomson International Inc. on 8/6/20. Two product samples (#1145947, 1145948) of red and white onions, respectively, 

were collected. On 8/4/20, CORE issued an assignment (eNSpect #169871) to ORA HAF6E (CHI-DO) for record collection at 

. On 8/5/20, USDA FSIS issued a Public Health Alert regarding the recall of RTE meat and poultry products that contained recalled 

onions. As a result of the Thomson International Inc (Bakersfield, CA) recall, multiple firms have initiated downstream recalls including: Giant Eagle (Pittsburgh, PA), 

Taylor Farms (Dallas, TX), Walmart (Bentonville, AR) Food Lion (Salisbury, NC) Publix Super Markets (Lakeland, FL) and The Kroger Co. (Cincinnati, OH). As of

OC: OCC; CDC; CFIA, PHAC 

Purpose: To discuss talking points and identify speakers for the upcoming firm call with 

Sysco 

(b) (4)

Items Discussed: 

Agenda for Pre-call: 

 Roll Call 

 General situational awareness updates 

o 8 subclusters supplied by Sysco. We’ve received records related to the 

Canadian traceback, but US records are still pending. Canada is planning on 

public communications. 

o 3W had a meeting with Sysco this morning to explain purpose of call and 

agenda. Explained 4 agencies. Discussion regarding public comms 

o Sysco has pushback and apprehension wanted to know if they would be 

named 

o Kari got a heads-up phone call from Sysco last night. Sysco felt like they only 

knew of one subcluster associated with Sysco. 

 Proposed agenda 

o Introductions 

o Canadian outbreak investigation overview 

i. PHAC epidemiology update 

ii. CFIA regulatory update 

o US outbreak investigation overview 

i. CDC epidemiology update 

ii. FDA traceback update 

o Discussion regarding public communication 

 Talking points 

o PHAC 

i. 115 confirmed cases. Number of case clusters at restaurants and living 

facilities. Onions, tomatoes, leafy greens have been id’d as common 

food. Red Onions have been id’d as likely source. Red onions were 

supplied by Sysco, no similarities among other food items. 

o CFIA 

i. May make formal recall request of product sent to Canada. Or at least 

an indication that it is in the works. If recall, then Sysco would be 

named publicly. (*OCC doesn’t think it’s an issue to name suppliers 

later because we are not naming sysco in our press release)

Traceback Investigation Summary 

EON 371142 

For internal FDA use only. This summary contains confidential, commercial information 

and may not be released outside FDA without appropriate redaction. 

Traceback Abstract 

A regulatory traceback was initiated for four legs

(b) (4)

 points-of-service (POS) in response to an 

outbreak of Salmon lla Newport illnesses. As of 10/08/2020, there were 1,132 culture-confirmed 

illnesses in 48 states [AK (25), AL (2), AR (2), AZ (39), CA (128), CO (32), CT (2), DE (2), FL 

(8), GA (11), HI (3), ID (43), IL (54), IN (4), IA (31), KS (3), KY (3), ME (6), MA (2), MD (7), 

MI (47), MN (19), MO (11), MS (5), MT (72), NC (6), ND (9), NE (10), NH (1), NJ (12), NM 

(3), NV (14), NY (14), OH (11), OK (1), OR (110), PA (27), RI (3), SC (1), SD (24), TN (7), TX 

(2), UT (115), VA (10), WA (150), WI (11), WV (3), WY (27)]. CDC identified red onions as 

the vehicle of interest. Reported onset dates ranged from 06/19/2020 to 09/11/2020. 

Four traceback legs representing 26 cases were initiated on 07/21/2020. Factors used in 

identifying “best cases” were: more than one case at a single POS with exposures to red onions. 

Case patients included in the traceback investigation had known meal/exposure dates which 

ranged from 06/19/2020 to 07/15/2020. The timeframe of interest for record collection was 

identified as two weeks at POS for known meal dates and three weeks for onset dates. 

The four traceback legs converged on Thomson International Inc, LLC (Bakersfield, CA). 

A summary of each traceback leg, including data analysis discussion, follows: 

Traceback Leg 1 (Sysco Montana POS Leg) 

Points-of Service: 

 Thomson International Inc, LLC; 11220 S. Vineland Rd., Bakersfield, CA 93307-9489 

(b) (4) (b) (4) Page 1 of 21

(FOUO) For Official Use Only 2020-Nov-03 



















The traceback investigation identified four legs of distribution for red onions served 

(b) (4)

 

 

Development. The points-of-service identified in the traceforward product flow diagram indicate 

if red and/or yellow onions sourced from Thomson International Inc, LLC were known to have 

been supplied at some time; this does not indicate if the onions were the onions that were 

consumed by the cases, just known distribution. Additional grocery companies identified in the 

recall audit check and downstream recalls included: ALDI, Food Lion, Giant Food, Hello Fresh, 

Imperfect Foods, Kroger, Publix Super Markets, Stop & Shop, Walmart, and WinCo. 

Conclusion 

. Thomson International Inc (Bakersfield, CA) was identified as the source of 

the red onions based on convergence of the legs of traceback. Additional information from 

traceback investigations performed by the Canadian Food Inspection Agency, the California 

Department of Public Health and the Michigan Department of Agriculture & Rural Development 

support this conclusion 

Limitations 

This traceback investigation was limited by the exposure information provided by cases in 

identified clusters, the size of illness clusters identified, limited supply chain diversity identified, 

and lack of adequate recordkeeping. Epidemiologic information regarding case exposures was 

limited when cases were unable to recall the type of onions consumed. The majority of the 

clusters, nine of ten, were less than four cases per point-of-service. Three of the four legs of red 

onion traceback were through various Sysco distribution centers and did represent a broader 

diversity of supply chains. 

Records were not available or were incomplete at some points along the distribution chains:

 did not identify Sysco as a supplier, but later records from Sysco identified it as 

such; records at Thomson International Inc, LLC for field level information were known to be 

incorrect and information used in this traceback was the best information that the firm could 

(b) (4)

identify.
