The FDA declared an E. coli outbreak linked to Trader Joe’s chicken wraps over, with 50 people reported sick. The agency has not identified the contaminated ingredient, and says the wraps were already off the market and past their expiration dates. Separately, the FDA is investigating a Salmonella Javiana outbreak with 59 confirmed patients as of Oct. 28.
The FDA has declared an E. coli outbreak linked to Trader Joe’s chicken wraps over, after 50 people were reported sick, while a separate investigation into Salmonella Javiana has reached 59 confirmed cases. The agency has not identified the ingredient responsible for the E. coli contamination, and says the wraps were removed from sale before investigators established the outbreak link.
In an Oct. 28 update, the FDA said illnesses in the E. coli outbreak occurred during one week in August. The wraps had been removed from the market before the connection was established, and the products consumers had eaten were past their shelf life. The agency said more detailed product information would not have given consumers an action they could take to prevent illness.
The FDA and the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) have not named Trader Joe’s in their public outbreak reports. However, FSIS confirmed to USA Today that Trader Joe’s was the source of the chicken wraps, according to Food Safety News. The agencies share investigative responsibilities because the wraps contain chicken, overseen by FSIS, and other ingredients that fall under FDA jurisdiction.
The FDA says its outbreak investigation remains active. It reported that investigators are tracing ingredients, conducting onsite inspections and testing samples, but did not identify the ingredients, locations or samples involved. FSIS also says it is continuing its investigation without publicly releasing further details. The FDA update lists 50 people sickened; it does not provide a new case count or say that investigators found the specific source of the E. coli.
Why the Unidentified Ingredient Matters
Declaring an outbreak over does not necessarily mean investigators have identified how contamination occurred. Here, the agencies say the wraps were no longer available for sale and had passed their shelf life, while the FDA’s investigation remains active. That leaves the contaminated ingredient and the route of contamination unresolved publicly.
The case count also may not capture everyone who became ill. Food Safety News reports that CDC estimates 26 infections may go undetected for each confirmed E. coli patient, because some people do not seek medical care or are not tested specifically for E. coli. This is an estimate about undercounting, not a revised count of illnesses in this outbreak.
For consumers, the agency’s explanation is that the implicated wraps were already off the market, so further product details would not prompt a current action to avoid them. The separate Salmonella and Listeria investigations, however, show why outbreak counts and food sources can remain under review after an initial public update.

How the Wrap Investigation Developed
The FDA and FSIS are both involved because the product combines chicken with other ingredients overseen by different agencies. Although Food Safety News reports that FSIS identified Trader Joe’s as the source when speaking to USA Today, neither agency named the chain in its own outbreak report. The distinction matters: the retailer identification is attributed to FSIS through the newspaper’s account, while the agency updates themselves do not name it.
The FDA’s Oct. 28 update said the illnesses occurred in one week in August and that the wraps were removed before investigators established a link to the outbreak. It described ongoing traceback, inspection and testing work but did not disclose specific products or businesses under examination. The agency’s declaration that the outbreak is over refers to the outbreak status; it does not mean every investigative question has been answered.
In other food-safety updates reported alongside the wrap investigation, the FDA listed 59 confirmed Salmonella Javiana patients as of Oct. 28, with the source not yet identified. A separate Listeria monocytogenes outbreak rose from 46 to 50 patients in a week; the FDA said it had begun traceback, inspections and sample testing. The agency also closed an investigation into 18 Cyclospora cases associated with a catered lunch, but its published summary was heavily redacted and did not identify the caterer or a suspect food.
“The implicated wraps were proactively removed from the market before the link to the outbreak was established.”

What Investigators Have Not Identified
The FDA has not said which ingredient carried the E. coli, what sites are being inspected, or what samples are being tested. The public update does not explain what findings led investigators to associate the wraps with the outbreak. FSIS has not published details of its continuing work in the material cited by Food Safety News.
The new Salmonella Javiana outbreak’s source is also unknown. As of Oct. 28, the FDA had not provided patient ages or locations. The Listeria investigation likewise lacks publicly described foods or inspection locations in the report, and additional cases may be counted: the source report notes that Listeria symptoms can take up to 70 days to develop. These are separate investigations; the available information does not connect them to the chicken wraps.
Further Agency Findings Expected
The FDA says work on the E. coli investigation is continuing through ingredient traceback, onsite inspections and sample testing, while FSIS is also investigating. Neither agency has announced when it will release more findings or whether it will identify a specific ingredient or supplier. No new consumer action tied to the wraps was described in the Oct. 28 update, which said the products were already off sale and past their shelf life.
For the Salmonella Javiana outbreak, investigators still need to identify a source; the FDA’s reported count stood at 59 confirmed patients as of Oct. 28. The Listeria count and investigation may also change as cases are reported and testing proceeds. Any later agency update could clarify the food sources, case totals and investigative findings, but those details were not available in the report.
Key Questions
Has the FDA declared the chicken-wrap E. coli outbreak over?
Yes. The FDA’s Oct. 28 update described the outbreak as over. The agency also said its investigation remains active, so the closure status does not mean the source has been publicly identified.
Were the wraps identified as Trader Joe’s products?
Food Safety News reports that FSIS confirmed to USA Today that Trader Joe’s was the source of the wraps. Neither the FDA nor FSIS named the chain in the outbreak reports described in the article.
How many people were reported sick in the E. coli outbreak?
The report gives a total of 50 people sickened. It also notes that confirmed counts can miss infections, but it does not provide a revised estimate for this outbreak.
What caused the E. coli outbreak?
The FDA has not publicly identified the contaminated ingredient or explained the route of contamination. It said investigators are tracing ingredients, conducting inspections and testing samples, without disclosing what or where those activities involve.
What is the status of the new Salmonella outbreak?
The FDA was investigating a separate Salmonella Javiana outbreak with 59 confirmed patients as of Oct. 28, 2026. The source had not been identified, and the agency had not released patient ages or locations in the report.
