Summary

TWO SURVEYS FOR THE PRESENCE AND TYPE OF CLOSTRIDIUM BOTULINUM IN FRESH SEAFOOD OBTAINED FROM LOCAL SUPERMARKETS, PROCESSORS, A FISH FARM, AND A STATE HATCHERY WERE CONDUCTED BETWEEN 1984 AND 1987. THE AUTHORS FIRST ANALYZED 166 SAMPLES REPRESENTING 14 TYPES OF FISH AND 5 OTHER TYPES OF SEAFOOD. AN OVERALL PREVALENCE OF 21.7% WAS FOUND. THE SECOND SURVEY EXAMINED 54 SAMPLES OF FRESH FILLETS REPRESENTING 15 TYPES OF FISH. SEVENTY GRAMS OF HOMOGENATE WERE VACUUM PACKAGED AND INCUBATED AT 303 K (30 DEG C) FOR 3 D. OF THE 54 SAMPLES, 36 RESULTED IN TOXIN PRODUCTION. THE HIGH PREVALENCE OF NONPROTEOLYTIC SPORE TYPES ISOF PARTICULAR SIGNIFICANCE WHEN CONSIDERING THE RISK OF C. BOTULINUM GROWTH IN FRESH AND MINIMALLY PROCESSED SEAFOOD STORED FOR EXTENDED TIMES UNDER MODIFIED ATMOSPHERES AT LOW TEMPERATURES.
