Biosecurity measures preventing exposure of pigs to rodents, wildlife, and contaminated feed or waste products reduce the risk of zoonotic infection in pork. To understand the benefits of such measures in the United States, we conducted the first comprehensive survey of pigs produced under the Pork Quality Assurance Plus production standard, surveying 3,208,643 pork samples from twelve processing locations tested over a period of 54 months. We detected no sp. positives in any of these pork samples, providing a 95% confidence in a sp. prevalence of <1 in 1,000,000 for the processors represented by the study. These results are consistent with international guidelines for having a negligible risk to public health. Results obtained here should generalize to all PQA+ sources, as sp. exposure risk is based on production guidelines that extend to the larger PQA+ population.
防止猪接触啮齿动物、野生动物以及受污染的饲料或废品的生物安全措施，可降低猪肉中人畜共患病感染风险。为了解此类措施在美国的益处，我们对符合“优质猪肉保障强化版”（Pork Quality Assurance Plus）生产标准的生猪进行了首次全面调查，在54个月的时间里对来自12个加工地点的3,208,643份猪肉样本进行了检测。在这些猪肉样本中，我们未检测到任何[具体物种]呈阳性，对于该研究涵盖的加工商而言，这表明[具体物种]的流行率在百万分之一以下的可信度为95%。这些结果与对公众健康风险可忽略不计的国际准则一致。此处获得的结果应适用于所有“优质猪肉保障强化版”来源，因为[具体物种]的接触风险基于适用于更大规模“优质猪肉保障强化版”群体的生产准则。
