Improvements in processing hygiene indicator and microbial hazard levels in Australian finisher pigs from 1996 to 2010

摘要

In 2010 a national pig carcase baseline survey was undertaken to help determine the impact of regualtion on processing hygiene and hazard levels and to inform national standard setting. The results are compared to those from a 1996 baseline survey of Australian finisher pigs. For E. coli a reduction in prevalence of around 10% (29.3% in 1996 to 20.7% in 2010) and an average reduction in concentration of 1.5 log10 cfu/cm2 were observed.
