Notes:
24-hr procedures suggested for the bacteriological evaluation of critical control points in the processing of frozen raw breaded shrimp were compared to official techniques on an interlaboratory basis. The 24-hr methods were designed to enumerate APC, total coliforms, E. coli, and coagulase-positive Staphylococcus aureus. The 24-hr APC was a standard plate count procedure using Eugon agar, while the abbreviated techniques for total coliforms, E. coli, and coagulase-positive S. aureus were 3-tube MPN procedures. The data gathered from 16 analytical laboratories comprising 18 series of frozen raw breaded shrimp subsamples were subjected to a least mean square analysis to determine the effects of technique, the bivariate interaction technique x laboratory, and the variable “SM” which embodied the sample source and month processed. The analyses of variance indicated that there were no differences between techniques for APC, total coliforms, and E: coli at the 5% level of significance. The bivariate interaction, technique x laboratory, was not significant at the 5% level for these tests indicating a consistent relationship between the means for the 24-hr and official methods for the various tests. The difference between the 24-hr and official method for coagulase-positive S. aureus was significant at the 10% level and the interaction, technique x laboratory, was highly significant. The variable SM was highly significant for all tests.
