Over the past year, there have been 14 recalls for oysters after foodborne illness outbreaks, primarily due to norovirus infections. Five of those outbreaks / recalls occurred over the past 4 months (below), with the last one due to oysters harvested in Louisiana.
Raw oysters are a risk for viral and bacterial pathogens. As filter feeds, they capture the contaminants in the water column and those contaminates are consumed when the oysters are eaten raw. The government requires shellfish identification tags to be placed on the shellfish when harvested and these tags accompany the shellfish to the point of sale, at which point, they must be kept on file in the event of an outbreak. This allows investigators to identify the site in which the oysters were harvested and then issue a source specific recall.

The oysters were harvested from Louisiana Area 3 from 1/10/2025 through 2/4/2025.
