متن کاملInfluence of Pigskin on Salmonella Contamination of Pig Carcasses and Cutting Lines in an Italian Slaughterhouse
Ninety pig carcasses and twenty one food contact surfaces (FCSs) were tested for Salmonella in a slaughterhouse processing ca. 380 pigs/h between 2014-2015. Sampling was performed during seven sessions. Four carcass sites of 100 cm2 each (back, belly, jowl externally, and the diaphragmatic area internally) were swabbed after evisceration.

متن کاملIs the Salmonella contamination of swine carcasses at slaughter related to the Salmonella load in caecum?
The aim of this study was to examine the relationship between the load of Salmonella spp. in caeca and the carcass contamination in an Italian slaughterhouse. The sampling scheme was designed to be representative of the pigs slaughtered in a day and to estimate a 12% prevalence of pigs highly contaminated by Salmonella spp. (HCP, cecal load ≥3log). Environmental swabs were taken before slaughte...
متن کاملIdentification of Salmonella spp. and Salmonella typhimurium by a multiplex PCR-based assay from poultry carcasses in Mashhad- Iran
Poultry meat has been identified as one of the principal foodborne sources of Salmonella. In this preliminary study the prevalence of Salmonella spp. and its typhimurium serovar contamination of broiler carcasses, were determined. Using the rinse test method, numbers of 60 samples, representing 20 broiler flocks, were collected from poultry carcasses after the chilling stage in the processing l...
متن کاملEfficacy of using a sponge sampling method to recover low levels of Escherichia coli O157:H7, Salmonella typhimurium, and aerobic bacteria from beef carcass surface tissue
Recovery of aerobic bacterial populations, as well as low levels of Escherichia coli O157:H7 and Salmonella typhimurium from beef carcasses was determined by sponge (SP) and excision (EX) sampling during the course of three separate studies. For the first study, samples were taken from three points on the processing line: (1) pre-wash, (2) post-wash, and (3) after 24 h in the chill cooler. SP r...
