Summary

TOXIN PRODUCTION IN SHUCKED SCALLOPS BY A MIXTURE OF 10 STRAINS OF CLOSTRIDIUM BOTULINUM (TYPES A, B, E, F) WAS STUDIED USING MOUSE BIOASSAY. SCALLOPS, WITH OR WITHOUT 0.1% POTASSIUM SORBATE, WERE PACKAGED IN AIR-PERMEABLE FILM OR VACUUM PACKAGED IN IMPERMEABLE FILM. TWO TRIALS WERE DONE IN WHICH PACKAGES WERE INOCULATED WITH DIFFERENT SPORE LEVELS AND HELD AT 277, 283 AND 300 K (4, 10 AND 27 DEG C). BACTERIAL COUNTS WERE MADE ON VARIOUS SELECTIVE MEDIA. ONLY TYPE A TOXIN WAS OBSERVED AND THIS ONLY IN EVACUATED PACKAED0K TOXIN DEVELOPED MORE RAPIDLY IN THE PRESENCE OF SORBATE. ALL PACKAGES IN WHICH TOXIN WAS RECORDED HAD OFFENSIVE ODOURS AND WERE VISIBLY SPOILED. THE POTENTIAL HAZARD FROM BOTULISM IS DISCUSSED.
