Abstract
A steam-vacuum sanitizer reduced aerobic plate counts associated with bovine faecal contamination from 5.5 log(10) cfu cm(-2) to 3.0 +/- 0.2 1 log(10) cfu cm(-2) on beef carcass short plates. The same beef carca ss short plates inoculated with 7.6 +/- 0.09 log(10) cfu cm(-2) Escher ichia coli O157:H7 in faeces, yielded an average residual level of E. coli O157:H7 of 2.1 +/- 0.21 log(10) cfu cm(-2), after steam-vacuum tr eatments. This study demonstrates the effectiveness of a steam-vacuum sanitizer for removing E. loll O157:H7 from beef carcasses.
