Additional outbreak information
The table below shows information about outbreak investigations being managed by FDA’s CORE Response Teams. The investigations are in a variety of stages. Some outbreaks have limited information with active investigations ongoing, others may be near completion. The table below has been abbreviated to show only active investigations.

public health advisory will be issued for investigations that have resulted in specific, 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 rely on self-reported data. Although these reports may name a particular product, FDA will only indicate a product category in the table and will not publicly name a specific product until there is sufficient evidence to implicate that product as a cause of illnesses or adverse events. If a cause and/or contributing factors are identified that could inform future prevention, FDA commits to providing a summary of those findings.
