Identification of main contamination points by hygiene indicator microorganisms in beef processing plants

Practical Aspects of Beef Carcass Traceability in Commercial Beef Processing Plants Using an Electronic Identification System

The use of an electronic identification (EID) system in slaughter facilities holds great potential as a tool for animal and carcass traceability, if used as part of a comprehensive carcass tracking system. However, the correct association of each carcass with its individual EID tag number may be hindered at several points during the slaughter process. For 2,994 cattle slaughtered in 14 lots and...

Isolation and identification of Salmonellae from chicken carcasses in processing plants in Yazd province, central Iran

This study was conducted to determine the prevalence of Salmonellae contamination of chicken carcasses in slaughterhouses in central Iran (Yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. The results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....

Processing Plants Contamination in Fish Feces : a Source of in

Source tracking of Escherichia coli O157:H7 and Salmonella contamination in the lairage environment at commercial U.S. beef processing plants and identification of an effective intervention.

Transportation from the feedlot and lairage at the processing plant have been identified as potential sources of Escherichia coli O157:H7 and Salmonella hide contamination. The objective of this study was to perform a comprehensive tracking analysis of E. coli O157:H7 and Salmonella associated with beef cattle from the feedlot through processing. Cattle (n = 581) were sampled in a feedlot, then...
