New Mexico Reports More H5N1 in Dairy Cows as California Probes Possible Outbreaks on 3 Farms

By Lisa Schnirring

The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) today confirmed another H5N1 avian flu outbreak in a dairy herd in New Mexico, the state’s first since the middle of April.

The outbreak pushes the nation's total confirmed outbreaks in dairy facilities to 194 in 13 states.

Though the pace of H5N1 outbreaks on dairy farms has slowed over the summer months, federal officials said at a briefing earlier this month that it was too soon to say if the virus was ebbing in cattle. They noted that cattle movement between states, which played a role in initial spread, picks back up in the fall due to greater demand for milk, partly due to schools resuming.

Suspected outbreaks in Central Valley

The California Department of Food and Agriculture yesterday announced that it is investigating the possible introduction of the virus into three dairy farms in the state’s Central Valley. It said samples have been sent for testing to California Animal Health and Food Safety laboratory. If positive, they will be considered "presumptive" and submitted to the USDA for confirmation.

In early June, WastewaterSCAN launched an H5 wastewater dashboard to help track undetected H5 spread, and, since then, traces of the virus have been found in nine states, seven of which have reported H5N1 outbreaks in dairy cows. California and Arkansas were the only two states with positive H5 wastewater findings that hadn't reported recent outbreaks on dairy or poultry farms.

California is the nation's top milk production state and accounts for one fifth of the nation's supply. The state has about 1,100 dairy farms, and herds in Tulare, Merced, and Stanislaus counties make up just more than half of the state's milk output.

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.
