Variability of Escherichia coli and Enterobacteriaceae counts on pig carcasses: A systematic review

摘要: Abstract Background Indicator bacteria are considered an interesting target for microbiological analysis in order to obtain information about the hygiene of processes and products. Quantitative targeting indicator offers several advantages over pathogenic since prevalence counts higher, their distribution is more homogeneous, than pathogens. However, although criteria addressing already place industrialised countries such as EU US, on factors affecting carcasses at slaughter scattered. Objectives The aim this review was provide valuable variability along pig slaughterline, suggest suitable means implementation GMP (Good Manufacturing Practices) process slaughterhouses. Conclusions Along scalding chilling stages effectively reduce both Escherichia coli Enterobacteriaceae have be HACCP systems. Surface pasteurisation under experimental conditions also effective; contrast, washing did not microbial contamination carcasses. Evisceration confirmed a key point, particular regarding , but it has been suggested that bacterial load can controlled by anal plugging if performed according good manufacturing practices (GMP).
