FDA Closes E. coli Outbreak Linked to Trader Joe's Chicken Wraps

The FDA declared an E. coli outbreak that sickened 50 people officially over on Oct. 28, closing an investigation tied to chicken wraps sold at Trader Joe's — a connection the agency itself never formally confirmed.

Neither the Food and Drug Administration nor the USDA's Food Safety and Inspection Service named the grocery chain in their outbreak reports. The FSIS confirmed to USA Today that Trader Joe's was the source. Both agencies are involved because the wraps contain chicken, which falls under FSIS jurisdiction, while the remaining ingredients fall under FDA jurisdiction.

Why no source was named publicly

Both agencies said they withheld the source because the wraps are past their expiration date and no longer available for sale.

"The implicated wraps were proactively removed from the market before the link to the outbreak was established. At the time of this action, illnesses occurred during one week in August. Since these products were removed from sale and the wraps people ate were out of shelf life, more detailed product information would not have provided consumers with an action they could take to prevent illness. FDA's outbreak investigation remains active," the FDA reported in its Oct. 28 outbreak update.

The FDA said it is tracing ingredients, conducting onsite inspections and testing samples. It has not disclosed what is being traced, which locations are being inspected or what is being tested. The USDA says it is also continuing to investigate, without releasing details.

The official count of 50 likely understates the outbreak's true scale. Some sick people never seek medical care, and others are not specifically tested for E. coli. The CDC estimates that for every confirmed patient in an E. coli outbreak, 26 cases go undetected — a ratio implying the actual toll could exceed 1,300.

Three other outbreak fronts

• Salmonella Javiana: The FDA is investigating a new outbreak with 59 confirmed patients as of Oct. 28. No source has been identified. The agency is not reporting patient details such as ages or locations.
• Listeria monocytogenes: The patient count rose from 46 to 50 in the past week. The outbreak was first posted Sept. 23. The FDA has begun traceback, onsite inspections and sample testing but is not disclosing the food being traced or the locations involved. More patients are possible: Listeria symptoms can take up to 70 days to develop.
• Cyclospora: The FDA closed its investigation of a catered-lunch outbreak that sickened 18 people. The agency never named the caterer, the event or the source of the parasite, and posted a heavily redacted Executive Incident Summary Abstract.

What does the redacted Cyclospora report contain?

The abstract, covering an outbreak first flagged by CDC on June 5, 2026, shows the investigation traced produce through a single point of service and a sole produce distributor. It confirms 18 cases across an undisclosed number of states, with two hospitalizations and no deaths as of Sept. 3, 2026.

"No single produce item could be named as the suspect ingredient based on the epidemiologic information collected; no apparent supplier connection to other Cyclospora clusters in the 2026 season was identified," the summary states. No FDA laboratory samples were collected, and no product or firm actions were taken.

With the E. coli investigation still officially active and the Salmonella Javiana and Listeria probes expanding, the FDA faces a widening set of open outbreak fronts heading into November.
