The FDA has declared an E. coli outbreak linked to Trader Joe’s chicken wraps over, after 50 people were reported sick. The agency has not publicly identified the source ingredient, and says its investigation remains active. Separately, the FDA is investigating a Salmonella Javiana outbreak 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, while saying its investigation into the outbreak remains active. The agency is also investigating a separate Salmonella Javiana outbreak that had 59 confirmed patients as of Oct. 28, 2026; officials have not identified its source.
The FDA’s Oct. 28 outbreak update said the chicken wraps implicated in the E. coli illnesses had been removed from sale before investigators established the outbreak link. The illnesses occurred during one week in August, according to the agency. The wraps people ate were past their shelf life, the FDA said, and the products were no longer available for consumers to act on.
Neither the FDA nor the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) named Trader Joe’s in its public outbreak reports. However, FSIS confirmed to USA Today that Trader Joe’s was the source of the wraps, according to Food Safety News. The agencies are both involved because FSIS oversees the chicken and the FDA oversees the wraps’ other ingredients.
The FDA said it was conducting ingredient traceback, onsite inspections and sample testing, but its update did not identify the ingredients being traced, the locations being inspected or the samples being tested. FSIS also said it was continuing its investigation, without publicly providing further details. The FDA’s declaration that the outbreak is over does not mean all investigative work has stopped.
What the Outbreak Closure Means
The end-of-outbreak designation tells consumers that the agency does not report the wrap-related illnesses as an ongoing outbreak. The FDA said the implicated products had already been removed from sale and were past their shelf life, so it did not provide more detailed product information that could guide a current purchase or disposal decision. No current recall or consumer action is identified in the supplied update.
The reported 50 illnesses may not represent everyone who became sick. Food Safety News cited the CDC estimate that for every confirmed E. coli patient, 26 cases may go undetected, because some people do not seek care or are not tested specifically for E. coli. That figure is a general estimate, not a confirmed count of additional cases in this outbreak.
The separate Salmonella investigation matters because its source is still unknown. With 59 confirmed patients as of Oct. 28 and no reported source, consumers do not have enough information from the update to connect the illnesses to a particular food or business. The FDA has not published patient ages or locations.

Two Agencies, Separate Food Oversight
The chicken-wrap investigation involves both federal food-safety agencies because the product combines foods that fall under different jurisdictions: USDA FSIS oversees poultry, while the FDA oversees the other ingredients. Their public reports had not named the retailer, even though FSIS confirmed the connection to USA Today, as reported by Food Safety News.
The FDA’s explanation for withholding more product details was that the wraps had been removed before the outbreak connection was established and were no longer within their shelf life. The agency said further product information would not give consumers an action to take to prevent illness. At the same time, it described investigative work as ongoing, leaving the cause within the wraps unidentified publicly.
Other outbreak updates in the same report included a Listeria outbreak whose count rose from 46 to 50 in a week. The FDA had begun traceback, inspections and testing but did not name a food source. It also closed its investigation into a Cyclospora outbreak linked to a catered lunch, reporting 18 confirmed cases and posting a heavily redacted summary that did not identify a suspect ingredient or the caterer.
“The implicated wraps were proactively removed from the market before the link to the outbreak was established.”
— FDA outbreak update, Oct. 28
Source and Case Details Still Missing
The FDA has not publicly identified which ingredient in the wraps, if any, carried the E. coli, or provided the locations inspected and samples tested. The public update also does not detail the evidence supporting the outbreak link. The source of contamination remains undisclosed, and the supplied material does not say whether investigators reached a final conclusion about it.
For the Salmonella Javiana outbreak, the FDA has not named a food, supplier or business as the source. It also has not reported patients’ ages or where they live. The case count is a snapshot as of Oct. 28, 2026; the material does not establish whether more cases have since been confirmed.
The official count of 50 illnesses in the E. coli outbreak may understate the number of people who became ill, but the cited CDC estimate cannot be used to calculate a confirmed outbreak total. The number of undetected cases in this specific event is unknown.
Further Agency Findings Awaited
The FDA says its work on the chicken-wrap outbreak remains active, including traceback, inspections and sample testing. FSIS also reports that it is continuing its investigation. The agencies have not announced when they will release additional findings or whether they will identify a specific ingredient or source.
For the Salmonella Javiana investigation, the next useful update would identify a suspected or confirmed source, provide more information about the affected patients, or report a changed case count. No such finding is included in the Oct. 28 update, so the investigation’s next milestone and timing remain unknown.
