Abstract
Sixty six samples of frozen fishery products consisting of frozen crab meat, frozen
prawns, frozen cuttle fish and frozen mussel collected from nine cold stores situated in
and around Cochin city were examined for coagulase positive staphylococci. Forty
eight samples (72.72%) revealed the presence of coagulase positive staphylococci, which were then tested for enterotoxigenity, employing cellophane-over-agar method for·
toxin production and optimum-sensitivity-plate (OSP) method for toxin detection.
Seventy seven out of one hundred and two (75.49%) coagulase positive staphylococcal
isolates from the above products produced enterotoxins A, B, C, D and E either singly
or in combinations. Enterotoxin A and D were detected more often than others.
The occurrence of enterotoxigenic staphylococci in frozen fishery product is reported
for the first time in this country.
