Number of patients increases in Salmonella outbreaks; other ongoing investigations

The number of patients in two outbreaks of infections attributed to different types of Salmonella continues to rise, according to the FDA.

Three more patients have been identified in an outbreak of Salmonella Senftenberg infections, bringing the total to 22, the Food and Drug Administration reported Aug. 24. The agency has yet to identify a food source in the outbreak, which was first reported this past week. Tracing efforts have begun, but the FDA has not reported what or what foods it was tracing.

In another Salmonella outbreak, this one caused by Salmonella Typhimurium, the number of patients rose to 62, from 44 reported last week. Traceback efforts have begun, as well as sample collection and analysis, but the FDA has not reported which foods or foods are traced or tested.

For an outbreak of E. Coli infections linked to Wendy’s sandwiches with romaine lettuce, the FDA has begun an on-site inspection but did not say which locations are being investigated. The inspection process could involve restaurants, growers, packers or distributors of the suspected romaine lettuce.

Two outbreaks of infections with the Cyclospora parasite were combined into a single investigation based on genomic data provided by the Centers for Disease Control and Prevention. No product or products have been identified as the source of the infections.

“For Cyclospora outbreaks in products not yet identified, cases from Cyclospora outbreak reference #1084 (in the table below) have been aggregated into the other Cyclospora outbreak reference #1080”, according to an update from the FDA. “For Cyclospora outbreak reference #1080, the case count has been adjusted from 6 cases to 70 and for Cyclospora outbreak reference #1084, the case count has been adjusted from 98 cases to 41 cases.”

Other outbreak investigations ongoing as of August 24

  • An investigation related to adverse reactions associated with Daily Harvest brand frozen leek and lentil crumbs. The company has received more than 470 disease complaints, and as of its last July 29 report, the FDA had received 329 complaints. Some of the patients suffered from liver failure and at least 25 had to have their gallbladders removed. The FDA is working on traceback efforts and has begun on-site inspection and product testing. Some tests have revealed that tara flour is a unique ingredient in the Daily Harvest crumbles product and may be linked to disease.
  • An outbreak of “adverse events” involving 558 patients who consumed Lucky Charms cereal. The investigation is ongoing and the FDA is conducting on-site inspections and testing.
  • An outbreak of Listeria monocytogenes infections has been traced to Florida-produced Big Olaf ice cream. A total of 25 confirmed patients have been reported with one death and fetal loss. Patients are spread across 11 states, and many sufferers said they traveled to Florida before falling ill. Testing showed Listeria in the manufacturing plant and in 16 of 17 flavors of Big Olaf ice cream. The company has been closed by the state until further notice.
  • An outbreak of Cronobacter infections in four infants, one of whom died. The outbreak has been determined to be over by the CDC, but is still under investigation. The babies consumed formula made by Abbott Nutrition’s factory in Sturgis, MI.

A public health notice will be issued for investigations that result in specific, actionable steps consumers should take to protect themselves, according to the FDA. Please direct your attention to these pages for the most up-to-date investigation information and for consumer protection information.

Investigations of outbreaks and adverse events that do not result in specific, actionable actions for consumers may or may not conclusively identify a source or reveal contributing factors. Adverse event surveys rely 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 enough evidence to implicate that product as the cause. illnesses or adverse events. If a cause and/or contributing factors are identified that could inform future prevention, the FDA agrees to provide a summary of those findings.
