Survival of Staphylococci on frozen fish
Using Staphylococcus aureus as the test culture it has been shown that cell injury occurs in two phases during freezing and storage at temperatures below freezing. Certain constituents of fish muscle appear to protect the cells during both phases of injury. The survival of bacteria on fish muscle is not influenced by the rate at which the fish muscle was frozen prior to inoculation. There was no significant difference between growth of bacteria on quick frozen and slow frozen fish muscle after thawing. However there appeared to be a slight tendency for the lag phase of growth to be extended on thawed quick frozen fish muscle when compared with thawed slow frozen muscle.
