A steam-vacuum sanitizer reduced aerobic plate counts associated with bovine faecal cantamination from 5·5 log10 cfu cm-2 to 3·0 ± 0·21 log10 cfu cm-2 on beef carcass short plates. The same beef carcass short plates inoculated with 7·6 ± 0·09 log10 cfu cm-2 Escherichia coli 0157:H7 in faeces, yielded an average residual level of E. coli 0157:H7 of 2·1 ± 0·21 log10 cfu cm-2 after steam-vacuum treatments. This study deomonstrates the effectiveness of a steam vacuum sanitizer for removing E. coli 0157:H7 from beef carcasses.
