Microbiologic analyses were performed on foil pack meal components which had been precooked and frozen. Food lots were compared on the basis of conformance and nonconformance of total bacterial plate counts and of total coliform counts to the current Military Specifications MS. The proportion of meat lots rejected at Francis E. Warren AFB was higher than at the School of Aerospace Medicine P .05. At the .05 level, no difference was detected in the proportion of vegetable lots rejected by both laboratories. Most of the total plate counts and total coliform counts were much lower than the maximum allowed by the MS. Consequently, the recommendation will be made to change the bacterial requirements to total plate count not greater than 30,000 per gram, instead of 100,000 per gram and to total coliform count of 10 per gram, instead of 100 per gram. Various microbiologic methods recommended by other food technology groups were performed for the recovery of Salmonellae and coagulase-positive staphylococci. Author
