The USDA has shared its plans to start testing bulk raw milk to identify potential bird flu contamination, this is a proactive step to manage the spread of the h5N1 virus, which is highly contagious. The decision has been made due to the significant impact of the virus on poultry, over 100 million chickens have been affected, and recent detections have been made in dairy herds, primarily in California. In collaboration with state veterinarians, the USDA intends to strengthen biosecurity measures and limit risks for farm workers who may be exposed to the virus.
Dairy meets biosecurity
The roll-out of testing and protocols will be conducted by the USDA’s Animal and Plant Health Inspections Service (APHIS), targeting bulk raw milk specifically. To identify H5N1 presence in dairy herds, the testing will be done in infected areas.
- Contamination Range: H5N1 has infected more than 400 herds nationwide. In California alone, over 200 herds were impacted.
- Inspection Method: Phased plan alongside state veterinarians to analyze and control H5N1’s reach across dairy farms.
Feathered intruder alert!
USDA’s concern in raw milk testing derives from the transmission potential between livestock and humans. This is an opportunity to diminish risks related to the virus.
“Data collected over the past seven months has shown that H5N1 can be transmitted on equipment, people, or other items that move from farm to farm, including between dairies and poultry facilities.” USDA
Milk it for safety
USDA’s decision arises from industry calls for more detailed and improved biosecurity and monitoring, due to the fast circulation of H5N1 and its possible effects on public health and food safety.
- Test Success: Prior testing in Colorado dairy farms showed that monitoring measures limit the virus’s spread.
- Farm Workers Protection: This testing model will contribute to protecting farm workers who interact with possibly infected livestock. These actions are crucial considering the virus shows signs of adaptation in other species.
No fowl play here
- Heightened Observation: Recollection of milk samples from bulk supplies, aims for early detection in affected regions.
- Low Consumer Risk: H5N1, E. coli, and other pathogens are effectively neutralized by pasteurization, guaranteeing the safety of pasteurized milk products. Still, raw milk remains a concern.
- Expanded Virus Spread: Virus adaptability and the need for observation were underscored in Oregon when the first pig infected with H5N1 was reported.

Farmers fight
Actions of bulk raw milk testing could impact Ingredient suppliers who source dairy products. They should verify they partner closely with approved dairy-sourcing suppliers who adhere to strict biosecurity procedures, considering the USDA’s policy on disease prevention. There might also be a shift in additional requirements for dairy imports and testing protocols.
Collaboration among suppliers with different agencies, such as USDA and CDC, plays a crucial role in dealing with public health and agricultural challenges. These agencies optimize processes and consolidate efforts to ensure effective policies across federal and state levels. The involvement of farmers and dairy producers in the testing process is crucially important, as well as their experiences and insights about the challenges faced on the ground. These collaborations foster a proactive approach to disease management and enhance the resilience of the agricultural sector.
Blast from the past
Stricter biosecurity measures spotlight the necessity for vigilance in monitoring diseases that threaten animal health and food security. These measures have been established since the Avian Influenza outbreaks in the early 2000s and 2015. There were consequences after this, especially economic ones such as the culling of millions of birds. This impacted poultry prices drastically, as well as farmer’s livelihoods. The government’s responses have evolved from reactive measures to proactive strategies. Including vaccination, surveillance, and the integration of technology to improve disease prediction and response. Adaptability and innovation in practices have been proven essential for resilience against disease threats.
