Bird flu hits dairy herds across the United States

Published 2024년 4월 1일

Tridge summary

The United States has reported cases of highly pathogenic avian influenza (HPAI) in dairy herds across several states, including Texas, Kansas, Michigan, New Mexico, and Idaho, as confirmed by the USDA and NVSL. Originating from wild migratory birds, the disease has caused a decrease in milk production and appetite in cows, though with minimal mortality and most animals recovering. The USDA recommends good biosecurity and isolation practices to curb the spread. There is no current threat to humans or the commercial milk supply, with the FDA specifically advising against the consumption of raw milk from affected herds. Australia remains vigilant but unaffected, monitoring potential impacts on its poultry and wildlife.

The United States Department of Agriculture confirmed on March 25 the highly pathogenic avian influenza (HPAI) had been detected in two dairy herds in Texas and two dairy herds in Kansas. The USDA's National Veterinary Services Laboratories (NVSL) later confirmed the presence of HPAI in a Michigan dairy herd that had recently received cows from Texas. Dairy herds in New Mexico and Idaho were also positive to initial testing - but are still awaiting final confirmation of the disease from the NVSL. Wild migratory birds are believed to be the source of infection - likely pigeons, blackbirds and grackles in Texas. At this stage the disease is causing lower milk production, lower appetite and other symptoms in affected animals, but most have recovered after isolation with little to no associated mortality reported. ...
