进行了一项全国范围的调查，以估计加拿大商业肉鸡群中肠炎沙门氏菌和其他沙门氏菌的流行率。 随机选择的 294 只鸡群中有 226 只 (76.9%) 的环境（垫料和/或水）样本受到沙门氏菌污染。 垃圾样本比水样本更容易受到沙门氏菌污染（47.4% vs. 12.3%）。 分离出五十种不同的沙门氏菌血清型。 最常见的血清型是哈达尔链球菌、婴儿链球菌和黑链球菌。它们分别从 98/294 (33.3%)、26/294 (8.8%) 和 21/294 (7.1%) 鸡群的样本中分离出来。 39/290 (13.4%) 鸡群的饲料样本受到沙门氏菌污染。 从 9/294 (3.1%) 鸡群的环境样本中分离出肠炎沙门氏菌。 从七个鸡群中分离出肠炎沙门氏菌噬菌体类型 (PT) 8，从两个鸡群中分离出 PT 13a。
A nation-wide survey was conducted to estimate the prevalence of Salmonella enteritidis and other salmonellas among Canadian commercial broiler flocks. Environmental (litter and/or water) samples from 226 of 294 (76.9%) randomly selected flocks were contaminated with salmonellas. Litter samples were more often contaminated with salmonellas than water samples (47.4 v. 12.3%). Fifty different salmonella serovars were isolated. The most prevalent serovars were S. hadar, S. infantis, and S. schwarzengrund; they were isolated from samples of 98/294 (33.3%), 26/294 (8.8%), and 21/294 (7.1%) flocks, respectively. Feed samples of 39/290 (13.4%) flocks were contaminated with salmonellas. Salmonella enteritidis was isolated from the environmental samples of 9/294 (3.1%) flocks. Salmonella enteritidis phage type (PT) 8 was isolated from seven flocks, and PT 13a from two flocks.
