摘要：

The occurrence of Clostridium botulinum in fresh (67) and cured fish (278) samples in retail trade in Cochin was studied. An overall prevalence of 19% (13/67) was found in fresh retail fish and types A to D were detected in the positive samples. In pelagic fish, incidence of C. botulinum was 18% (7/39) whereas in demersal fish, 21% (5/24) of the samples harboured C. botulinum. Incidence of C. botulinum in shrimp was 25% (1 :4) and type D was found in the positive sample. Of 257 cured fish in retail trade tested for the presence of C. botulinum, the overall contamination level leas 10% (25/257). Among the C. botulinum types A to D prevalent in fresh fish, types C and D were the predominant types found in cured products. In salt-dried shrimp, of the 21 samples analysed, 10 samples (48%) harboured C. botulinum. (C) 2002 Elsevier Science B.V All rights reserved.
