Raw Gulf Oysters Seasonal Restrictions

Printer Friendly
Font Size Extra Large Font Size Large Font Size Default

The sale of raw, untreated Gulf oysters harvested from April 1 to October 31 is restricted in California.  Persons with certain chronic diseases, especially those associated with liver disease are at high-risk for Vibrio vulnificus infections. Fifty percent of high-risk individuals, who become ill, die. These restrictions strive to improve public health protection for consumers of raw Gulf Oysters.

Gulf oysters that have been subjected to a validated treatment process are exempted from the restrictions.  Food facilities that serve or offer for sale treated Gulf Oysters must have on file a current copy of their shellfish supplier’s certificate of “Verification of Oyster Treatment Process” from the CDPH.

The California Department of Public Health's web site has information regarding shellfish processing companies that have current certificates of "Verification of Oyster Treatment Process." (Select Food Safety under Organization, then select Shellfish & Seafood Safety under Specific Food Programs).

The following shellfish processing companies have current certificates of “Verification of Oyster Treatment Process”:
