Bird flu outbreak at another US dairy farm, 40 cows infected

Minnesota has reported its first case of bird flu in a dairy herd, adding to the ongoing virus outbreak in the United States.

The affected farm, Derrydale Farm in Belle Plaine, detected the virus in more than 40 cows. The animals showed signs of fever, according to the Minnesota Board of Animal Health.

The farmer reported the symptoms on Monday, and testing by the US Department of Agriculture’s (USDA) National Veterinary Services Laboratories confirmed the positive results on Wednesday night.

The milk from the infected cows was thrown away, and the entire herd has been quarantined for 30 days. After this period, the herd will be retested to confirm the absence of the virus before the quarantine is lifted.

This is not the first time Minnesota has tested dairy farms for avian flu, but it is the first confirmed positive case.

Since late March, over 80 dairy herds across 11 states have been infected, with Minnesota now joining the list. The virus has also infected three dairy workers nationwide.

The other states with reported infected herds include Colorado, Idaho, Iowa, Kansas, Michigan, New Mexico, North Carolina, Ohio, South Dakota, and Texas.

While some infected cows have died or been slaughtered, the USDA states that most recover from the illness.
