H5N1 arrives: poultry culling methods, vaccine debate and pet food recalls
In brief
A MedCram medical education video covers H5N1 avian influenza: Savage Pet and West Coast Raw cat foods were recalled after H5N1 detection, with cats in Colorado and New York infected via the products. About 500 million birds have been culled globally since the outbreak began, including 166 million in the US, with 27 million more in the past two months. China, Egypt and Vietnam use non-sterilizing vaccines in chickens, prompting a US import ban on their poultry; the Trump administration is reportedly considering mass US vaccination, opposed by RFK Jr.
Key points
- Presenter Roger Seheult mentioned H5N1 detected in cat food: Savage Pet and West Coast Raw (West Coast LLC) issued recalls on March 1 and March 15; cats in Colorado and New York were infected via these products, with one case recovering; H5N1 has a high fatality rate in cats.
- An FDA-funded Cornell study showed that aged cheese made from raw milk of dairy cows infected with avian influenza can carry infectious H5N1 virus for months, and the virus in refrigerated raw milk remained infectious for 8 weeks; the presenter noted that HHS Secretary RFK Jr's claim that 'disease does not spread through food' is only partially true.
- Since the avian influenza outbreak, roughly 500 million birds worldwide have been culled, with a case fatality rate of about 90% in chickens; the US has culled about 166 million cumulatively and the UK about 3 million, with the US culling 27 million in the past two months alone (about 9% of the US total).
- The US uses 'Ventilation Shutdown,' raising temperatures in sealed poultry houses to about 70°C/158°F to kill the birds; in March 2022, Rembrandt Enterprises in Iowa used this method to kill 5.3 million chickens; the UK switched to nitrogen and carbon dioxide asphyxiation, considered more humane.
- Governments compensate farmers for losses: the US has paid about $400 million this year and $1.1 billion cumulatively since 2021; the UK paid about $42 million in 2022; meat and eggs from culled birds may not be marketed.
- China, Egypt, and Vietnam vaccinate chicken flocks against H5N1, and the US therefore bans poultry meat imports from these countries; these are non-sterilizing vaccines that only reduce disease/death rather than preventing infection. After France vaccinated ducks, cases dropped from about 400 to 10, but it faced a US trade embargo; the Trump administration is reportedly considering mass poultry vaccination in the US, while RFK Jr has publicly opposed it.
