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-2 Escherichia coli O157:H7 in faeces, yielded an average residual level of E. 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.
一种蒸汽真空消毒器可将牛肉胴体短板上与牛粪污染相关的需氧平板计数从5.5 log10 cfu cm-2降至3.0±0.21 log10 cfu cm-2。在粪便中接种7.6±0.09 log10 cfu cm-2的大肠杆菌O157:H7的相同牛肉胴体短板，经蒸汽真空处理后，大肠杆菌O157:H7的平均残留水平为2.1±0.21 log10 cfu cm-2。本研究证明了蒸汽真空消毒器从牛肉胴体上去除大肠杆菌O157:H7的有效性。
