The microbiological profiles of kangaroo carcasses and minced meat at game meat processing plants in South Australia were determined in surveys undertaken in 2002 and 2004. In 2002 mean values for log(10) total viable counts (TVC) on carcasses at individual plants ranged from 0.9 to 3.

A trial on the effectiveness of acidified sodium chlorite (ASC) on Salmonella and Campylobacter was undertaken on chicken carcases after they exited the screw chiller of a commercial premises in Adelaide, Australia. On untreated carcases mean log10 total viable count (25 degrees C) was 2.78/cm2 compared with 1.

During the 1990s, there was radical change in regulation of meat and poultry hygiene in Australia, and Australian Standards were developed for each sector of the meat industry. Systems for industry/government co-regulation and company-employed meat inspection were introduced based on company HACCP programs approved and audited by the Controlling Authority. However, in the 5 years since regulatory changes took full effect, rates of salmonellosis have not decreased (surveillance and reporting systems have remained unchanged).

Article Synopsis
  • A study sampled 523 chilled beef and lamb carcasses from South Australia to assess the microbiological quality of meat for domestic consumption.
  • Findings showed mean aerobic viable counts (AVCs) were lower in beef from very small plants (VSPs) compared to larger abattoirs, but E. coli prevalence was significantly higher in samples from abattoirs.
  • The results aim to help the controlling authority improve meat hygiene practices and align production methods with national safety standards.
