Pathogenic Vibrio cholerae 0-Group 1 survived for more than 3 weeks in artificial sea water with little loss in viability. Live oysters placed in such contaminated, artificial sea water took up but did not concentrate V. cholerae. Heat treatments provided by an in-can pasteurization process and by preparation of naturally contaminated oysters according to common recipes effectively reduced the numbers of V. cholerae by 5 logs/g.
