BACTERIOLOGICAL SURVEY ON SALMONELLA SEROVARS FROM SLAUGHTERED CATTLE

Although more than 2400 Salmonella serovars have been identified worldwide, only about a dozen serovars account for more than 75% of the isolates reported from human beings and animals. Bacterial pathogens are especially of most serious concern regarding the issues of meat safety to consumers. In the present study standard ISO 6579 method was used to
investigate the presence of salmonellae in slaughtered cattle. Salmonellae were detected in 28 % gall bladder samples, 24 % duodenum samples, 10 % hide swabs,10 % liver samples, 8 % Pre-femoral (pre- corral) lymph node swabs, 6 % Pre-scapular lymph node swabs and 0 % raw muscle meat samples. Salmonella isolates were identified as S. Muenster (n=17), S. Typhimurium (n=15), S. Kentucky (n=4), S. Anatum (n=3), S. Nyborg (n=3) and S. Livingstone (n=1).
