Abstract

Following reports of highly pathogenic avian influenza H5N1 infections of dairy cattle in the United States in March 2024, we established a Pan-Canadian Milk network to monitor retail milk in Canada. Milk samples from across Canada that had previously tested negative for influenza A virus (IAV) RNA were tested for the presence of anti-IAV nucleoprotein (NP) antibodies as an indicator of past infection of dairy cattle. None of the 109 milk samples tested had evidence of anti-IAV NP antibodies. This is consistent with previous findings from our academic group as well as others including federal testing initiatives that have not found any IAV RNA in milk. Although not surprising given that no cases of H5N1 in cattle have been reported in Canada to date, this work further supports that the extensive outbreak in dairy cattle in the United States has not extended northward into Canada, and the integrity of the Canadian milk supply remains intact.

没有证据表明加拿大零售牛奶中存在抗流感核蛋白抗体(2024年4月至7月)。
继2024年3月美国出现高致病性禽流感H5N1感染报告后,我们建立了一个泛加拿大牛奶网络来监测加拿大的零售牛奶。来自加拿大各地的牛奶样本先前对甲型流感病毒(IAV) RNA检测呈阴性,并对其进行了抗IAV核蛋白(NP)抗体的检测,作为奶牛过去感染的指标。109份检测的牛奶样本中没有发现抗iav NP抗体的证据。这与我们的学术小组以及包括联邦测试计划在内的其他人之前的发现是一致的,他们没有在牛奶中发现任何IAV RNA。鉴于到目前为止加拿大还没有牛感染H5N1病例的报告,这并不令人惊讶,但这项工作进一步支持了美国奶牛的大规模暴发没有向北扩展到加拿大,加拿大牛奶供应的完整性仍然完好无损。
