The FDA has declared an E. coli outbreak associated with chicken wraps sold by Trader Joe’s over, though it has not named the retailer in its own public reports or identified the source of contamination. Separately, the agency is investigating a Salmonella Javiana outbreak with 59 confirmed patients as of Oct. 28, 2026; its source has not been identified.
The FDA has declared the E. coli outbreak linked to chicken wraps sold by Trader Joe’s over, after 50 people were reported sick, while a separate Salmonella Javiana outbreak remains under investigation with 59 confirmed patients as of Oct. 28. The source of the E. coli contamination has not been publicly identified, and the FDA has not named Trader Joe’s in its outbreak report.
The FDA said the wraps had been removed from sale before their connection to the outbreak was established and were past their shelf life by the time of its update. The agency said illnesses occurred during one week in August. It reported that the investigation remains active, even though it has marked the outbreak as over.
Federal agencies have not named the grocery chain in their public investigation reports. However, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) confirmed to USA Today that Trader Joe’s was the source of the chicken wraps, according to Food Safety News. The wraps contain chicken, which falls under FSIS jurisdiction, as well as other ingredients overseen by the FDA; both agencies are involved.
The FDA said it was conducting ingredient traceback, onsite inspections and sample testing, but did not disclose which ingredients or sites were involved or what was tested. The USDA also said it continues to investigate the E. coli outbreak, without releasing further details. Separately, the FDA reported 59 confirmed patients in the Salmonella Javiana investigation and said it had not identified a source.
Why the Wraps’ Source Remains Unknown
The end-of-outbreak declaration does not answer the central food-safety question: what ingredient or handling step carried E. coli. The agencies say the product was no longer being sold and had passed its expiration date, so they concluded that more detailed product information would not give consumers an action to take to avoid illness. The FDA nevertheless says its investigation remains active.
For shoppers, the distinction matters. The outbreak is considered over, but that does not mean investigators publicly established a contamination source or described how the product became unsafe. The agencies’ explanation also means consumers cannot use the report to identify a specific ingredient or location to avoid. The separate Salmonella investigation is a current public-health concern, but the available update does not connect it to Trader Joe’s or to the chicken wraps.
Outbreak counts are not necessarily a full measure of illness. Food Safety News cited the CDC estimate that for every confirmed E. coli patient, 26 infections may go undetected. That is a general estimate, not a count of additional people known to have been sickened by these wraps.

How the Federal Investigations Overlap
The wrap investigation involves two federal agencies because the product combines foods regulated by different authorities: FSIS oversees the chicken, while the FDA oversees the other ingredients. The agencies have not publicly identified the specific product details or contamination source in their reports. FSIS’s confirmation to USA Today, as described by Food Safety News, provides the public link to Trader Joe’s, but the agencies’ own reports do not name the retailer.
The same Oct. 28 FDA update covered other foodborne illness investigations. A separate Listeria monocytogenes outbreak count rose from 46 to 50 in the past week, and the agency said it had begun traceback, inspections and sample testing without naming the food under investigation. The FDA also closed an investigation into 18 Cyclospora cases associated with a catered lunch. Its posted summary was heavily redacted and said investigators could not identify a single suspect produce item.
Those other investigations are distinct from both the chicken-wrap E. coli outbreak and the Salmonella Javiana probe. The FDA has not reported a shared source among them. The Listeria count may change because the agency said symptoms can take up to 70 days to develop.
“The implicated wraps were proactively removed from the market before the link to the outbreak was established.”

What Investigators Have Not Disclosed
The agencies have not publicly identified the specific E. coli source, the ingredient involved, or the locations inspected and samples tested. The FDA’s explanation is that the wraps were off the market and past their shelf life; it has not described what its continuing investigation may establish or when it might release further findings. The public reports also do not provide details of the USDA’s ongoing work.
For the Salmonella Javiana outbreak, the source remains unknown. The Oct. 28 update gave a count of 59 confirmed patients but did not include ages, locations or other patient details. It is also unclear whether additional cases will be identified. The available information does not establish a link between this outbreak and the E. coli case, the Listeria investigation or the closed Cyclospora inquiry.
Further Findings From FDA and FSIS
The FDA says it is continuing work on the E. coli investigation, including traceback, inspections and testing, while FSIS says its investigation is also ongoing. No release date for additional findings has been provided. Readers should look to future updates from the FDA and FSIS for any newly disclosed source information or changes in the outbreak status.
The FDA’s Salmonella Javiana investigation is also ongoing, with its source unidentified in the latest update. The agency may revise the case count or provide more information as the investigation develops. No specific next milestone or timetable was included in the material available as of Oct. 29, 2026.
Key Questions
Is the E. coli outbreak linked to Trader Joe’s chicken wraps over?
The FDA has declared the outbreak over. It also says its investigation remains active, so the outbreak status and the continuing search for information are separate matters.
Did the FDA name Trader Joe’s in its report?
No. The FDA and FSIS did not name the retailer 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.
Has the E. coli contamination source been identified?
Not in the public information provided. The agencies have not identified the contaminated ingredient or other source. The FDA said it was conducting traceback, inspections and testing but did not specify the details.
What is known about the new Salmonella outbreak?
The FDA reported 59 confirmed Salmonella Javiana patients as of Oct. 28, 2026. The source has not been identified, and the update did not provide patient ages or locations.
