Abstract

W.J. DORSA, C.N. CUTTER AND G.R. SIRAGUSA. 1996. A steam-vacuum sanitizer reduced aerobic plate counts associated with bovine faecal contamination 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-2Escherichia coli O157: H7 of 2.1 ± 0.21 log10 cfu cm-2, after steam-vacuum treatments. This study demonstrates the effectiveness of a steam-vacuum sanitizer for removing E. coli O157 : H7 from beef carcasses.
