New US Testing Program Targets Dairy Stability Amid Avian Flu Worries

The US government’s new milk testing program could be our last defense against a deadly bird flu pandemic.

Let’s hope 2025 won’t look like 2020…

At a Glance

  • USDA mandates nationwide testing of raw milk for bird flu
  • 718 dairy herds in 15 states already affected by avian influenza
  • Testing begins December 16 in six states, aims to prevent virus spread
  • Concerns rise over potential human health risks and virus mutation
  • Commercial pasteurization effectively inactivates the virus in milk

USDA Takes Action Against Avian Flu Threat

The U.S. Department of Agriculture has ordered mandatory testing of the national milk supply for bird flu.

Uh oh.

This unprecedented measure comes as the highly pathogenic H5N1 avian influenza strain continues to spread across dairy farms, raising alarms about potential risks to human health and the integrity of our food supply.

The testing program, set to launch on December 16, will initially focus on six states: California, Colorado, Michigan, Mississippi, Oregon, and Pennsylvania. Entities handling raw milk, including bulk milk transporters and dairy processors, must now provide samples to the USDA upon request. This initiative builds upon a previous federal order from April, which required testing of lactating dairy cows before interstate shipping.

The Scope of the Avian Flu Crisis

The urgency of this testing program becomes clear when we consider the current state of the crisis. As of now, 718 dairy herds across 15 states have been affected by the bird flu. This rapid spread has raised significant concerns about the virus’s ability to transmit between mammals, potentially through raw milk consumption. The Centers for Disease Control and Prevention (CDC) has confirmed 58 human bird flu cases in the U.S., mostly from exposure to infected animals.

“Among many outcomes, this will give farmers and farmworkers better confidence in the safety of their animals and ability to protect themselves, and it will put us on a path to quickly controlling and stopping the virus’ spread nationwide,” Agriculture Secretary Tom Vilsack stated.

While symptoms in humans have been generally mild, health officials are not taking any chances. The CDC advises testing for those exposed, underscoring the potential for more severe outcomes if the virus were to mutate further. A study published in Science suggests that a single mutation could make the virus spread more easily between people, a scenario that could lead to a catastrophic pandemic.

Raw Milk: A Potential Vector for Transmission

One of the most concerning aspects of this situation is the potential role of raw milk in virus transmission. Despite warnings from the CDC about the risks associated with raw milk consumption, its popularity has been on the rise. This trend is particularly worrisome given that up to 30 states allow local sales of raw milk, even though the FDA regulates its sale across state lines.

The recent recall of raw milk and cream in California due to bird flu detection serves as a stark reminder of the potential dangers. While no human cases were linked to this specific incident, it highlights the critical importance of the USDA’s new testing program in identifying affected dairy herds swiftly and preventing the spread of the virus through the food supply chain.

While health organizations like the World Health Organization (WHO) and CDC currently consider the public health risk from bird flu to be low, they emphasize the importance of vigilant monitoring. The virus’s ability to spread efficiently between mammals, possibly through raw milk, underscores the need for this proactive testing approach.

It’s crucial to note that commercial pasteurization effectively inactivates the virus in milk, providing a safe option for consumers. However, the growing trend of raw milk consumption presents a potential loophole that could allow the virus to spread unchecked.
