CDFA Statement on Possible Introduction of Highly Pathogenic Avian Influenza at California Dairy Farms

The California Department of Food and Agriculture (CDFA) is investigating the possible introduction of highly pathogenic avian influenza (HPAI) at three dairy farms in the Central Valley. Should HPAI be confirmed, it is important to note that pasteurization is fully effective at inactivating the virus and there is no milk or dairy product safety concern for consumers.

With the detection of HPAI in dairies elsewhere in the US in recent months, CDFA has been engaged with private veterinarians, farmers and ranchers, and local, state and federal partners to develop response plans and actively monitor for the disease in livestock and poultry throughout California. CDFA has taken steps to reduce the risk of entry of infected dairy cattle into the state, has maintained rapid response capability used during past detections of HPAI in poultry, and is prepared to respond to detections in cattle.

If these cases are confirmed, CDFA will continue working closely with the California Department of Public Health, and local agricultural and public health officials, to understand the extent of the introduction and support animal health and public health activities with the goal of limiting exposure to virus while the impacted herds develop immunity.

Samples have been submitted from these three sites to our California Animal Health and Food Safety laboratory. Any positive tests at our California lab would be considered “presumptive” and submitted to the USDA for final confirmation (typically within a few days). As with most influenza infections in cattle, infected dairy cows would be expected to recover within a few weeks.

In this exclusive interview from the 2025 Iowa Pork Congress Rachel Fishback and Swineweb sit down with Tim Messinger, a seasoned expert from Precision Structures Inc. (PSI) of Wellman, Iowa, to delve into the latest trends and innovations in hog barn construction and remodeling.

With nearly two decades at PSI, Tim shares his journey from draftsman to sales, highlighting the company’s comprehensive services in building farrow-to-wean complexes, finishers, and nurseries. He emphasizes the critical role of proper site layout and grading in barn construction, ensuring long-term efficiency and scalability for pork producers.

Tim also discusses the increasing importance of advanced ventilation systems and smart controllers like Maximus and AP Edge, which offer producers enhanced monitoring and control over barn environments. As construction costs have risen, PSI has seen an uptick in remodeling projects, particularly in slat replacements, roof refurbishments and barn gating remodels to extend the lifespan of existing facilities.

A key takeaway from Tim is the value of partnering with reputable builders who offer robust post-sale support. PSI’s dedicated service team stands ready to assist clients 24/7, addressing emergencies and ensuring optimal barn performance.

For pork producers looking to build or upgrade their facilities, this conversation offers valuable insights into best practices and the latest industry developments.
