Microbiological quality of broiler carcasses during slaughter processing
Microbial contamination of poultry carcasses can be influenced by many factors during transport and slaughtering. The aim of this study was to evaluate the impact of four processing steps (plucking, evisceration, washing and chilling) on the total viable counts (TVC), counts of Escherichia coli, Salmonella spp. and Listeria spp. incidence on broiler carcasses. A total of 160 broiler carcasses o...
متن کاملDehydration indicators for broiler chickens at slaughter.
Freedom of (prolonged) thirst is considered to be of paramount importance for animal welfare. This emotion normally results from dehydration, which can be measured using physiological indicators. Because no reliable physiological indicator for thirst was available for broilers, we aimed to identify such a measure in this study. This indicator would ideally be integrated into quality control sys...
متن کاملThe effect of breed slaughter weight and nutritional management on cholesterol content of lamb carcasses.
This study was carried out to assess the effect of breed, sex, post-weaning nutrition, live weight at slaughter and their interactions on the cholesterol content in carcass fat of lambs. The carcasses were obtained from lambs of three indigenous Greek dairy breeds of sheep, the Boutsko (B), Serres (S) and Karagouniko (K) breed. After weaning (at approximately 42 days), the lambs of the three br...
متن کاملPre-slaughter factors affecting mortality, live weight loss, and carcass quality in broiler chickens
A field study was conducted to evaluate the influence of some pre-slaughter factors as journey time, stocking density, and lairage time on mortality, live weight loss and carcass defects on 321 flocks of broiler chickens slaughtered at a commercial processing plant. For each flock, the following traits were evaluated: birds dead-on-arrival (DOA); live weight loss; condemned carcasses; downgrade...
متن کاملAnalysis of a poultry slaughter process: Influence of process stages on the microbiological contamination of broiler carcasses
In a large-scale Swiss poultry abattoir, a microbiological process analysis of broiler carcasses was performed. At each selected process stage (scalding, plucking, evisceration, washing, and chilling), 90 carcasses from 30 flocks were sampled and examined for Campylobacter, Salmonella, Escherichia coli, Enterobacteriaceae, and extended-spectrum b-lactamases-producing Enterobacteriaceae. With re...
