Methods for obtaining maximum aerobic and anaerobic bacterial counts on fresh and irradiated (750,000 rad) shucked, soft-shelled clams and haddock fillets were investigated. This involved an evaluation of the composition and temperature of the dilution water, the composition of various culture media, the culture incubation temperature, and the culture incubation time. On the basis of the results of tests to determine the most suitable methods of counting, procedures and materials were selected for obtaining maximum aerobic bacterial counts and maximum counts for Clostridia in fresh and irradiated shucked, soft- shelled clams and haddock fillets. The bacterial content of shucked, soft- shelled clams from three plants, and of haddock fillets from three plants, was determined over a period of approximately one month. This survey involved the examination of three samples daily from each plant. While bacterial counts indicated that the product produced in some clamshucking and fish-filleting plants is superior in sanitary quality to that produced in others, no evaluation of different plants will be made until the survey has been completed and all data are available.
