The Salmonella prevalence in slaughter pigs of German origin was determined in seven abattoirs located in different regions of the country between February and June 1996. A total of 11,942 pigs delivered to the abattoirs in 752 batches, most of them comprised of pigs from individual finishing farms, was investigated by the bacteriological examination of faecal and gut lymph node samples, as well as of surface swabs taken from the carcasses. Salmonellae were isolated from 3.7% of the faecal samples, 3.3% of the lymph nodes and 4.7% of the surface swabs. The estimated overall prevalence of Salmonellae was 6.2% in the slaughter pigs, ranging between 1.9% and 12% in individual abattoirs. In the samples taken from carcasses, the estimated prevalence of Salmonellae reached 10.3%. 648 out of 752 batches could be included in a statistical analysis. No Salmonellae were detected in nearly 70 percent of the batches included in this analysis (n = 648). High Salmonella prevalences of more than 50 percent positive animals were detected only in 13 batches (2.0%). A statistically significant influence of the duration of the transport of slaughter pigs to the abattoirs or the waiting period in the abattoirs prior to slaughter could not be detected.
1996年2月至6月期间，在德国不同地区的7家屠宰场测定了德国原产屠宰猪的沙门氏菌流行率。对752批、共计11942头交付至屠宰场的猪进行了调查，其中大部分猪来自各个育肥场，调查方法是对粪便和肠道淋巴结样本以及从猪胴体采集的表面拭子进行细菌学检查。沙门氏菌在3.7%的粪便样本、3.3%的淋巴结样本和4.7%的表面拭子样本中被分离出来。估计屠宰猪中沙门氏菌的总体流行率为6.2%，各屠宰场的流行率在1.9%至12%之间。在从猪胴体采集的样本中，沙门氏菌的估计流行率达到10.3%。752批样本中有648批可纳入统计分析。在纳入该分析的批次（n = 648）中，近70%的批次未检测到沙门氏菌。仅在13批（2.0%）样本中检测到沙门氏菌阳性动物比例超过50%的高流行率情况。未检测到屠宰猪运输至屠宰场的时间或屠宰前在屠宰场的等待时间产生的统计学显著影响。
