FDA continues outbreak investigations

By Coral Beach on October 30, 2025

The Food and Drug Administration has advanced an investigation into one Salmonella outbreak and declared another one over.

For an outbreak of Salmonella Richmond that has sickened 11 people the FDA has begun an onsite inspection and sample testing but is not releasing information about what location is being inspected or what is being sampled. The agency previously began traceback efforts but has not reported what food it is tracing.

The FDA has also not released any information about the patients, including their ages or where they live. The agency first posted the outbreak on Oct. 16.

There are likely many more sick people in the outbreak than are on the confirmed patient list. This is because some people do not seek medical attention and many who do are not specifically tested for Salmonella. The Centers for Disease Control and Prevention estimates that for every confirmed patient in a Salmonella outbreak 29 go undocumented.

For an outbreak of Salmonella Lomalinda infections, the FDA is reporting that it has closed its investigation. There were 40 confirmed patients in the outbreak. The FDA did not report the patients ages or where they live.

The agency conducted traceback, onsite inspection and sample testing but did not report any specific details about those efforts. It remains unknown what caused the outbreak. The FDA first posted the outbreak on Sept. 1.
