Bacteriological investigations of prawn canneries 2. Incidence of Clostridium perfringens

Prawn processing factories of the three major fish processing centres of the West Coast of India, viz., Cochin, Mangalore and Calicut were surveyed to determine the occurrence of Clostridium perfringens in processing areas, and in processed products. Direct plating on Sulphite-polymyxin- sulphadiazine Agar and enrichment techniques were used. Samples of prawn, prawn guts, frozen prawns, canned prawns, water, ice, swab from utensils and soil from the factory premises were examined. Among a total of 461 samples examined, only 32 (6.9%) gave positive results. The incidence of C. perfringens was more in prawn guts (80%), followed by soil (50%), prawn (38%), ice (33.3%), frozen prawns (11%), swab (5.0%) and water (1.1%). No C. perfringens was isolated from canned prawns.
