A profile of the microbial safety of cheese in Canada was established based on the analysis of 2955 pasteurized and raw-milk cheeses tested under Canada's National Microbiological Monitoring Program (NMMP) and 2009 raw-milk cheeses tested under the Targeted Survey Program. 97.8% of NMMP and 99.6% of Targeted Survey cheese samples were assessed as being of satisfactory microbiological safety. Under the NMMP, Salmonella spp. was detected in 2 samples, Listeria monocytogenes was detected in 15 samples and no Escherichia coli O157/H7:NM (non-motile) was detected. Cheese samples assessed as having unsatisfactory levels of S. aureus and generic E. coli were found in 18 and 41 samples, respectively. Under the Targeted Survey, L. monocytogenes was detected in 2 samples, while no Salmonella spp. or E. coli O157/H7:NM were detected. Cheese samples assessed as having investigative and unsatisfactory levels of S. aureus were found in 4 and 2 samples respectively. No samples were found to have investigative or unsatisfactory levels of generic E. coli. For cheese samples collected under the NMMP, logistic regression models indicated that contamination was more frequent in raw-milk cheeses compared to pasteurized-milk cheeses (OR = 5.0, 95% CI (3.0, 8.3)), and in imported cheeses compared to domestic cheeses (OR = 8.18, 95% CI (4.1, 16.1)). A statistically significant association was found between cheese samples assessed as having unsatisfactory levels of generic E. coli and detection of L. monocytogenes, Salmonella spp. or levels of S. aureus that were assessed as unsatisfactory (p < .001). These test results will help support risk analysis and inform food safety decisions.

加拿大奶酪的微生物安全性。

根据对2955年在加拿大国家微生物监测计划(NMMP)下测试的巴氏杀菌和生奶奶酪和在目标调查计划下测试的2009年生奶奶酪的分析,建立了加拿大奶酪的微生物安全性概况。评估出97.8%的NMMP和99.6%的定向调查奶酪样品具有令人满意的微生物安全性。根据NMMP,沙门氏菌属。在2个样品中检测到单核细胞增生李斯特菌,在15个样品中检测到单核细胞增生李斯特菌,未检测到大肠杆菌O157 / H7:NM(非运动型)。奶酪样品被评估为金黄色葡萄球菌和一般大肠杆菌水平不理想分别在18和41个样本中发现。根据目标调查,在两个样本中检测到单核细胞增生李斯特菌,而没有沙门氏菌。或检测到大肠杆菌O157 / H7:NM。分别在4个和2个样本中发现被评估为具有调查性和不令人满意的金黄色葡萄球菌水平的奶酪样本。未发现样品中普通大肠杆菌的调查水平或令人满意的水平。对于根据NMMP收集的奶酪样品,逻辑回归模型表明,与巴氏消毒的奶酪相比,生牛奶奶酪中的污染更为常见(OR = 5.0,95%CI(3.0,8.3)),而进口的奶酪中与国产的相比奶酪(OR = 8.18,95%CI(4.1,16.1))。的统计学关联显著被评定为具有通用的不令人满意的水平的干酪样品之间发现大肠杆菌和检测单增李斯特菌沙门氏菌属。或被评定为不满意的金黄色葡萄球菌水平(p <.001)。这些测试结果将有助于支持风险分析并为食品安全决策提供依据。
