A STUDY OF THE EFFECTS OF SUB-STERILIZATION DOSES OF RADIATION ON THE STORAGE LIFE EXTENSION OF SOFT-SHELLED CLAMS AND HADDOCK FILLETS. Quarterly Progress Report, November 1961-January 1962

Technical Report ·
OSTI ID:4818089
Total aerobic-facultative and anaerobic macrocolony count data, together with the frequency distributions of aerobic-facultative isolates, are presented complete with analyses and interpretation for both haddock fillets and shucked, soft-shelled clams. The total microbial count of haddock fillets irradiated at 400,000 rad remained below 4 x l0/sup 5/gram during storage for two weeks at 0 deg C, whereas the non-irradiated controls attained counts of over 5 x l0/sup 7/ gram under identical conditions of storage, and had counts of over 6 x l0/sup 6/ gram after 8 days at this temperature. Fresh, non-irradiated shucked clams approached a state of bacterial spoilage (>1 x l0/sup 6/gram) after about a week in refrigerated storage, whereas samples irradiated at doses of 800,000, 750,000, 700,000, and 650,000 rad remained below l x l0/sup 4/gram after one month of storage under the same conditions.
