Studies on Microorganisms Contaminating Dressed Bovine Carcasses. I. Isolation of Aerobes with the Lapse of Time

Abstract

The contamination rate of bovine carcasses after dressing in the slaughterhouse was studied in the Fukuoka municipal meat market. It was the highest in the meat shop and decreased in the meat processing station and the meat market in the order listed.
Isolated were Escherichia, such Gram-negative intestinal rods as Hafnia, such gram-negative rods as Pseudomonas, Flavobacterium, Micrococcus, Sarcina, and Staphylococcus.
Escherichia was not so often isolated in the meat market, but predominantly in the meat shop. Pseudomonas and Flavobacterium were isolated from every location studied.
Micrococcus was isolated in every location and increased in number after cold storage. Lactobacillus was found in every location and increased in the meat shop.
