Salmonella should be absent from 50 grams. I also felt that a slightly
different standard should be made for cooked prawns, viz:—
Salmonella should not be present in 50 grams and Staphylococcus
aureus should be absent from 1 gram—I considered
10,000 per gram too high.
By the end of the year a total of 49 samples had been taken in
Bermondsey. No Salmonella organisms were isolated and, although
coagulase positive staphylococci were found to be present
in some samples, it could not be definitely stated that they would
cause food poisoning. All consignments were accordingly released.
Sampling of this commodity is continuing.
