兽医实验室调查和反应网络（Vet-LIRN）与食品紧急反应网络（FERN）及其微生物学合作协议计划（MCAP）实验室合作，进行了一项研究，以评估各种类型宠物食品中选定微生物的流行情况。这项盲法研究的目的是帮助兽医中心优先考虑未来潜在的宠物食品测试工作。该研究还提高了FERN实验室对动物饲料基质中食源性病原体的筛查能力，因为这些病原体也可能对接触宠物食品的消费者构成重大健康风险。六个美国人。S.美国食品药品监督管理局FERN MCAP实验室在2年内分析了大约1056份样本。实验室检测沙门氏菌、李斯特菌、大肠杆菌O 157：H7肠出血性大肠杆菌。大肠杆菌、产滋贺毒素的大肠杆菌. coli（STEC）。在第1阶段，对从当地商店购买的干燥和半湿润犬和猫食品进行了检测。在第2阶段测试了通过互联网购买的生狗和猫食品、外来动物饲料和肉干型零食。在480份干燥和半湿润样本中，只有2份检测呈阳性：1份为沙门氏菌，1份为李斯特菌。然而，在第二阶段分析的576个样本中，66个样本对李斯特菌呈阳性（其中32个是单核细胞增生李斯特菌），15个样本对沙门氏菌呈阳性。这些病原体是从生食和肉干型零食中分离出来的，而不是外来的动物干饲料。这项研究表明，生的宠物食品可能含有食品安全病原体，如李斯特菌和沙门氏菌。消费者应小心处理这些产品，并注意对人类和动物健康的潜在风险。
The Veterinary Laboratory Investigation and Response Network (Vet-LIRN), in collaboration with the Food Emergency Response Network (FERN) and its Microbiology Cooperative Agreement Program (MCAP) laboratories, conducted a study to evaluate the prevalence of selected microbial organisms in various types of pet foods. The goal of this blinded study was to help the Center for Veterinary Medicine prioritize potential future pet food-testing efforts. The study also increased the FERN laboratories' screening capabilities for foodborne pathogens in animal feed matrices, since such pathogens may also be a significant health risk to consumers who come into contact with pet foods. Six U. S. Food and Drug Administration FERN MCAP laboratories analyzed approximately 1056 samples over 2 years. Laboratories tested for Salmonella, Listeria, Escherichia coli O157:H7 enterohemorrhagic E. coli, and Shiga toxin-producing strains of E. coli (STEC). Dry and semimoist dog and cat foods purchased from local stores were tested during Phase 1. Raw dog and cat foods, exotic animal feed, and jerky-type treats purchased through the Internet were tested in Phase 2. Of the 480 dry and semimoist samples, only 2 tested positive: 1 for Salmonella and 1 for Listeria greyii. However, of the 576 samples analyzed during Phase 2, 66 samples were positive for Listeria (32 of those were Listeria monocytogenes) and 15 samples positive for Salmonella. These pathogens were isolated from raw foods and jerky-type treats, not the exotic animal dry feeds. This study showed that raw pet foods may harbor food safety pathogens, such as Listeria monocytogenes and Salmonella. Consumers should handle these products carefully, being mindful of the potential risks to human and animal health.
