FDA issued a health alert regarding oysters harvested from Cedar Key, FL harvested from December though February due to the potential for Salmonella contamination. "To date, there have been 8 cases linked to this outbreak within Florida, Georgia, and Alabama."
The issue of course, is when contaminated oysters are eaten raw or near-raw. Oysters, as filter feeders, are problematic when there are microbiological contaminants in the waters from where the oysters are harvested. More often we see viral contaminants - such as Hepatitis A or Norovirus or the bacterial foodborne pathogen species Vibrio vulnificus or Vibrio parahaemolyticus. But Salmonella is also a concern, as seen in this case.
The notice states "The FDA is advising consumers not to eat, and restaurants and food retailers not to sell, and to dispose of recalled wild harvest oysters from FL-3012, Cedar Key, Florida, harvested between December 16, 2022, and February 24, 2023, due to possible Salmonella contamination. These oysters were sold in Alabama, Florida, and Georgia. " "On February 24, 2023, the Florida Department of Agriculture and Consumer Services issued an emergency closure order for wild harvest oysters from harvest area FL-3012 and initiated a recall." That recall notice is posted below.
