Investigators from the Food and Drug Administration are working on a new Salmonella outbreak of unknown origin.
The Salmonella Enteritidis outbreak has sickened at least 18 people. The FDA has not reported the ages of the patients or where they live. The agency has initiated traceback efforts, but has not reported what food is being traced.
There are likely many more people who have been sickened in the outbreak than are reported at this time because the CDC estimates that for every confirmed Salmonella patient in an outbreak there are 29 patients who go unreported.
In other outbreak news, the FDA has determined that an outbreak of E. coli O26:H11 infections was likely due to alfalfa or clover sprouts. Public health officials conducted patient interviews and traceback investigations to determine the likely source of the pathogen.
“Although sprouts were confirmed as the vehicle, investigators were unable to determine which type of sprouts was making people sick,” according to the FDA.
The FDA first posted information about the outbreak on Oct. 30, 2024. Investigators confirmed 10 patients in the outbreak, but many more people were likely sickened. The Centers for Disease Control and Prevention reports that 26 patients go unreported for every confirmed patient in an E. coli outbreak.
Once investigators had enough information to confirm sprouts as the source of this outbreak, the products were past their shelf life and no longer available for sale.
