Four hundred and twenty pork carcasses from four abattoirs were examined for the presence of salmonellae by use of swabbing-enrichment techniques and contact plate methods. Carcasses from only one abattoir were found to be contaminated by swabbing-enrichment (23.3%) and contact plate (17.9%) methods. The area of the skin side of the ham, near the anal opening, was determined to be the area to examine for isolating salmonellae from pork carcasses with the greatest frequency. The most frequently isolated species of salmonellae in this study were Salmonella derby, S. anatum, S. typhimurium, and S. indiana.
通过棉签富集技术和接触平板法,对来自四个屠宰场的420头猪胴体进行了沙门氏菌检测。仅在一个屠宰场的猪胴体中,通过棉签富集法(23.3%)和接触平板法(17.9%)检测出有沙门氏菌污染。结果确定,靠近肛门开口处的火腿皮肤侧区域是从猪胴体中分离沙门氏菌频率最高的检测部位。本研究中最常分离出的沙门氏菌种类为德比沙门氏菌、鸭沙门氏菌、鼠伤寒沙门氏菌和印第安纳沙门氏菌。
