CDPH advises consumers to ask the retailer or restaurant about the source if the product is not labeled or identified.
According to the lab tests performed so far, multiple pathogens were identified: Vibrio parahaemolyticus (3), Vibrio albensis (1), Vibrio species unidentified (1), Shigella flexneri serotype 1 (2), and norovirus (1). One of the Vibrio parahaemolyticus cases was co-infected with non-O157 Shiga toxin-producing E. coli.
CDPH share some tips to prepare/consume oysters:
- Avoid eating raw and undercooked shellfish, including oysters, to reduce the risk of illness.
- If you do eat shellfish, cook it until it reaches an internal temperature of at least 145°F. A quick steaming isn't sufficient to prevent gastrointestinal illness from these pathogens.
