The FDA is investigating a new outbreak and has closed an investigation into another.
On Wednesday, the Food and Drug Administration announced a new outbreak of Salmonella Litchfield that has sickened at least 28 patients. The source of the pathogen has not yet been identified.
In its announcement of the outbreak, the FDA did not state the age of the patients or where they live. The agency also did not say if any patients have been hospitalized.
As of Wednesday night, the Centers for Disease Control and Prevention had not released any information about the outbreak. This is not unusual because the CDC generally waits until a specific pathogenic source is found.
The FDA has initiated tracing efforts, but has not disclosed which food or foods are being traced.
The agency has closed its investigation of an outbreak of infections caused by Salmonella Mississippi. The outbreak has been declared over without the source of the pathogen being determined. The FDA first published the outbreak on August 31. He reported that at least 103 patients were confirmed infected. The agency conducted a trace, but did not report which food or foods were traced.
An outbreak of Listeria monocytogenes continues with six patients. Tracing efforts have begun, but the FDA is not saying which food or foods are being traced. The cause of the outbreak remains unknown. The FDA has not disclosed the ages of the patients or where they live.

- For a Salmonella Typhimurium outbreak from an as-yet-unidentified food, the patient count has risen to 86, up from 84 reported a week ago. Tracing, on-site inspection, and sample analysis have begun, but FDA has not disclosed what is being traced or analyzed or where the inspection is taking place.
- For a Cyclospora outbreak, the patient count remains stable at 81. Tracing has begun, but the FDA has not reported what is being traced. Sample collection and analysis has begun and an on-site inspection has been initiated.
- For another Cyclospora outbreak, the patient count has held steady at 42. Tracing has begun, but the FDA has not reported what is being traced. Similarly, sample tests have started, but the agency has not reported what is being tested.
- An investigation into adverse effects associated with Daily Harvest brand frozen shredded leeks and lentils is ongoing. The company has received more than 470 illness reports, and according to its most recent report on September 15, the FDA had received 386 reports. Some of the patients suffered liver failure, and at least 25 had to have their gallbladders removed. The FDA is working on tracing efforts and has begun on-site inspection and product testing. Some tests have revealed that tara flour is an ingredient exclusive to the crumbled Daily Harvest product and could be linked to illnesses.
- In an ongoing outbreak of infections caused by E. coli O157:H7, the FDA has begun collecting and testing samples. The outbreak, reported by the CDC as linked to the lettuce in Wendy’s sandwiches, has sickened at least 84 people. The four-state outbreak has sickened more people based on state counts, but all reports have not reached the CDC. Wendy’s has stopped serving the hybrid of romaine and iceberg lettuce in sandwiches in several states, according to a statement from the company.
- The FDA is conducting an on-site inspection at Big Olaf Creamery in Florida, which is believed to be behind an outbreak of Listeria infections in 11 states. The state of Florida closed the business several weeks ago after tests found multiple locations of Listeria monocytogenes contamination at the plant. The tests also showed Listeria in 16 of 17 flavors of the company’s ice cream. At last count, the outbreak sickened 25 patients and one died. A pregnant woman also miscarried. Twenty-four of the patients have required hospitalization.
- An outbreak of Cronobacter infections in at least four babies, two of whom died. The CDC has determined that the outbreak is over, but it is still under investigation. The babies consumed infant formula made by Abbott Nutrition’s plant in Sturgis, MI.

A public health advisory it will be issued for investigations that have resulted in specific and actionable steps for consumers to take to protect themselves, according to the FDA. Please direct your attention to those pages for the most up-to-date information on the investigation and for consumer protection information.
Outbreak and adverse event investigations that do not result in specific, actionable steps for consumers may or may not conclusively identify a source or reveal any contributing factors. Adverse event investigations are based on self-reported data. Although these reports may name a particular product, the FDA will only list a product category in the table and will not publicly name a specific product until there is sufficient evidence to implicate that product in causing disease or adverse events. If a cause and/or contributing factors are identified that could inform future prevention, the FDA is committed to providing a summary of those findings.
