A total of 78 samples of frozen fish sticks were analyzed for total plate count, coliform count, coagulase-positive staphylococci and members of the Salmonella-Shigella group. Fifteen samples (19%) contained 50,000 organisms or more per g. and 4 had 100,000 or more per g. Coliform counts were generally low, ranging from zero to 35 per g., with 6 samples showing counts of 10 or more per g. Two samples contained coagulase-positive staphylococci and an isolate from one of these samples was positive to salmonella polyvalent sera.
