We bring alarming news from the heartland of our nation’s dairy production. A dairy herd in Colorado has recently tested positive for the Highly Pathogenic Avian Influenza A (HPAI) H5N1 virus. This recent case brings the total number of confirmed cases to an unsettling figure—34 across nine states. Unfortunately, that’s not all. These stats are per the United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS).
Today sees the effect of a new federal order in response to this threat. This important directive aims to contain the spread of this insidious virus by mandating testing before interstate movement of dairy cattle. It zeroes in specifically on the lactating dairy cattle. No matter the reason, whether for shows, sales, or transfers, the cattle moved across states line must undergo pre-movement testing for H5N1.
The pre-movement testing stipulates that testing must be carried out within seven days of moving these cattle, with accompanying documentation to affirm the health state. Notably, a Certificate of Veterinary Inspection (CVI) is now compulsory for all lactating dairy cattle crossing state lines. The necessity for caution cannot be overstated.
It’s critical to realize that this isn’t a regional problem. Rather, it’s infiltrated several dairy herds across states, from Idaho to Ohio, as evidenced by clinical samples, such as milk and tissue, drawn from diseased cattle. The unfortunate herds under attack are suffering a steep decrease in lactation, reduced appetite, amongst other symptoms. Nature, unfortunately, hasn’t been kind and it’s the dairy cows that bear the brunt, with significant drops in productivity and overall health.
Not surprisingly, the primary driver behind the outbreak seems to be animal movement within the dairy industry. This discovery underlines the need for stronger regulations and more strategic transportation methods. – Quoted from USDA
The situation isn’t just a concern for these poor animals. The CDC has reported at least one human HPAI A(H5N1) infection stemming from exposure to infected dairy cattle in Texas. While this might be a minute snapshot in an extensive picture, the possibility of HPAI A(H5N1) transmission through the consumption of raw, unpasteurized milk looms.
Dairy farms that house the affected cows should follow strict guidelines to protect their workers from exposure. This means, not only scheduling regular health inspections for staff, but also ensuring the treatment or pasteurization of raw milk and related products from exposed cattle.
Thankfully, there is power in collaboration. Not one, but four major agencies – the U.S. Food and Drug Administration (FDA), USDA, CDC, and state partners have come together to tackle this illness that has wreaked havoc among dairy herds in multiple states. Staying informed and proactive could make all the difference in protecting our dairy herds and our communities. After all, as Benjamin Franklin wisely said, “An ounce of prevention is worth a pound of cure.”
