The FDA has declared an E. coli outbreak linked to Trader Joe’s chicken wraps over after 50 people were reported sick, but the agency has not identified the source of contamination. A separate Salmonella Javiana outbreak is under investigation, with 59 confirmed patients as of Oct. 28, 2026.
The FDA has declared an E. coli outbreak linked to Trader Joe’s chicken wraps over, after 50 people were reported sick, but it has not identified the ingredient or source responsible. At the same time, the agency is investigating a separate Salmonella Javiana outbreak with 59 confirmed patients as of Oct. 28, according to Food Safety News.
The FDA’s Oct. 28 update said the implicated wraps had been removed from sale before investigators established a link to the illnesses. The reported illnesses occurred during one week in August, and the products people ate were past their shelf life by the time the investigation progressed. The FDA said the wraps were no longer available for consumers to take action on, but also said its investigation remained active.
Neither the FDA nor the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) named Trader Joe’s in their public outbreak reports. Food Safety News reported that FSIS confirmed to USA Today that Trader Joe’s was the source of the wraps. The agencies have not publicly identified the source of the E. coli contamination. Because the product contains chicken as well as other ingredients, FSIS and the FDA are both involved, with oversight split between the chicken and the other components.
The FDA said investigators were tracing ingredients, conducting on-site inspections and testing samples, but did not specify which ingredients, locations or samples were involved. The agency has also investigated a sprouting seeds outbreak. FSIS also said it was continuing its investigation, without releasing further details. Separately, the FDA’s new Salmonella Javiana investigation had 59 confirmed patients on Oct. 28; the agency had not provided patient ages or locations or identified a food source. For context on another Salmonella investigation, see the outbreak traced to backyard flocks.
Two Outbreak Investigations Continue
The end of the reported E. coli outbreak offers a status update, but it does not establish how the wraps became contaminated or which ingredient was responsible. The agencies’ explanation that the product was no longer on sale describes why they say a more specific public product notice would not give shoppers an action to take now. It does not mean the source has been identified: the FDA says its investigation remains active, and FSIS has also said its work continues.
For consumers, the new Salmonella investigation is a separate unresolved public-health issue. With 59 confirmed cases and no source named, the available update does not tell shoppers which food, if any, is linked to the illnesses. The case count is confirmed, but the missing food and location details limit what consumers can do beyond following official public-health notices and standard food-safety guidance.
The reported E. coli total may also understate the number of people who became ill. Food Safety News noted the CDC estimate that for every confirmed E. coli patient, 26 cases may go undetected. That estimate is a general undercount factor, not a verified count for this specific outbreak; the number of people affected beyond the 50 reported cases is unknown.

How the Wrap Investigation Developed
The FDA and FSIS are jointly involved because chicken falls under FSIS oversight, while the other ingredients in the wraps fall under FDA jurisdiction. The agencies have not publicly disclosed the specific source of contamination or detailed the evidence behind the reported association. The reported removal of the wraps from sale occurred before the outbreak link was established, according to the FDA’s update.
The FDA also reported changes in other investigations. Its Listeria monocytogenes outbreak count rose from 46 to 50 in the week before the Oct. 28 update; the agency had begun traceback, inspections and sample testing but had not identified the food being investigated in the information cited. The FDA said illnesses could still be added because Listeria symptoms can take up to 70 days to develop.
The agency closed an investigation into a Cyclospora outbreak involving 18 confirmed cases linked to a catered lunch. Its posted summary was heavily redacted and said investigators could not name a suspect produce item based on the epidemiological information collected. The summary reported two hospitalizations and no deaths. It did not identify the caterer, event or food source.
“The implicated wraps were proactively removed from the market before the link to the outbreak was established.”
— U.S. Food and Drug Administration, in its Oct. 28 outbreak update
The Contamination Source Is Unknown
The agencies have not disclosed which ingredient carried E. coli, how contamination occurred, or what the traceback and testing have found. The FDA has not identified the inspection sites or samples, and FSIS has not released details of its continuing work. The public information therefore does not establish a specific contamination point, despite the reported association with the wraps.
For the Salmonella Javiana outbreak, investigators have not named a food source, and the FDA has not shared patient ages or locations. It is not clear when the agency may release more information. The supplied reporting also does not establish whether the 59 cases share an exposure or whether additional illnesses will be confirmed.
The official E. coli count remains 50 in the source report. Although some infections can go undetected, the CDC estimate cited in that report cannot be used to calculate a confirmed total for this outbreak. Any number beyond the reported count would be an estimate, not a case count established by investigators.
Investigators Continue Traceback Work
The FDA says it is continuing ingredient traceback, on-site inspections and sample testing for the E. coli investigation; FSIS says its investigation is also ongoing. Neither agency has announced a public timetable for a final account or said when more details might be released. Any further update could clarify the product findings, the source of contamination, or the reasons investigators could not identify it.
For the Salmonella Javiana outbreak, the next key development would be identification of a food or other shared exposure, along with updated case information from public-health authorities. Until investigators announce a source or issue specific consumer guidance, the reported information does not support naming a particular food as the cause. Readers should check FDA and FSIS notices for any new findings or product action.
Key Questions
Has the FDA said the Trader Joe’s chicken-wrap outbreak is over?
Yes. The FDA’s Oct. 28 update declared the E. coli outbreak over. The agency also said its investigation remained active, so the declaration does not mean the source of contamination has been identified.
How many people were reported sick in the E. coli outbreak?
The source report gives an official count of 50 people. The actual number of infections is unknown; some people may not seek medical care or receive testing.
Did investigators identify what contaminated the wraps?
No. The FDA and FSIS had not publicly identified the ingredient or contamination source. The FDA said it was tracing ingredients, inspecting sites and testing samples but did not disclose details.
What is known about the new Salmonella outbreak?
The FDA was investigating a separate Salmonella Javiana outbreak with 59 confirmed patients as of Oct. 28, 2026. The food source and patient ages and locations were not reported in the source material.
