| Summary: | The microorganisms in Dungeness crabmeat (Cancer magister) and Pacific oysters (Crassostrea gigas) were identified by the replica-plating and computer analysis method. The initial flora of the shellfish and the flora change during storage at 7 C were determined. The microbial flora shifts in both shellfish were also determined after irradiation at 0.1 and 0.4 Mrad and during subsequent storage at 7 C. The Achromobacter species predominated in the initial flora of crabmeat (77.0%). The predominant position of this group increased to 99.2% after 0.1 Mrad and 100% after 0.4 Mrad. A large percentage of Lactobacillus was detected in oysters (55.0%). The Lactobacillus species were the predominant survivors after 0.1 Mrad (92.4%) but the predominant survivors after 0.4 Mrad were Achromobacter species (99.3%). |
