Microbiological status of rabbit carcases in Egypt

Abstract

A total of 40 New Zealand white rabbits, 20 freshly slaughtered rabbits from an experimental farm and 20 processed rabbit carcases from grocery stores in Beni-Suef city, were examined bacteriologically. The mean values of aerobic plate counts at 37 degrees C and 1 degrees C, Enterobacteriaceae counts, Pseudomonas counts and Staphylococcus counts of freshly slaughtered rabbits were 10(4) +/- 2 x 10(3), 8 x 10(2) +/- 10(2), 6 x 10(2) +/- 10(2), 3 x 10(2) +/- 10(2), and 10(2) +/- 60 organisms per gram respectively, whereas the equivalent values were 8 x 10(5) +/- 3 x 10(4), 2 x 10(5) +/- 10(4), 4 x 10(4) +/- 8 x 10(3), 2 x 10(4) +/- 6 x 10(3), and 4 x 10(3) +/- 4 x 10(2) organisms per gram of processed rabbit carcases from grocery stores, respectively. The freshly slaughtered rabbits showed a low bacterial load compared with processed rabbit carcases from grocery stores. Escherichia coli and Listeria monocytogenes could be isolated from the rabbit carcases examined in addition to Salmonella typhimurium, Pseudomonas aeruginosa and Staphylococcus aureus from processed rabbit carcases. Yersinia enterocolitica could not be isolated from any sample examined. Suggested measures to reduce the microbial load in rabbit carcases are discussed.
