The South Dakota Department of Agriculture and Natural Resources is reporting avian influenza, or chicken flu, was detected in a South Dakota dairy cattle herd.
DANR and the state Animal Industry Board, a board assigned to the state ag company, introduced Thursday the U.S. Department of Agriculture’s National Veterinary Services Laboratory confirmed a optimistic detection of the virus within the herd April 9. This is the primary confirmed case of chicken flu in a dairy farm in South Dakota.
Beth Thompson, South Dakota state veterinarian and head of the AIB, instructed the Argus Leader on Thursday optimistic samples had been taken from multiple cow.
Unlike avian influenza monitoring inside U.S. poultry, the Animal and Plant Health Inspection Service, a sub-agency of USDA, has not revealed which county the optimistic checks originated from.
“We’re solely happening so far as the state, primarily as a result of all of us need to defend the farmers and ranchers on the market as a result of there are fewer dairies that sit in a few of these states,” Thompson stated. “This goes to be ‘South Dakota 001.'”
According to APHIS, dairy herds in eight states have examined optimistic for the virus. As of Thursday, this checklist consists of one Idaho herd, three Kansas herds, two Michigan herds, 5 New Mexico herds, one North Carolina herd, one Ohio herd, one South Dakota herd and 10 Texas herds.
Thompson stated avian influenza has managed to afflict various different mammals, equivalent to bears, seals and skunks, which factors to its infamous capacity to evolve and have an effect on different species.
South Dakota’s poultry amenities have been hard-hit by the virus, which the USDA designates amongst meat and egg birds as extremely pathogenic — close to 100% dying charges. Of the greater than 82 million business birds culled on account of avian influenza since February 2022, about 5.37 million of these birds had been from South Dakota’s turkey, egg laying and even some upland sport farms.
The unfold of this pressure of avian flu has been attributed to migratory wild birds, Thompson stated. According to the Centers for Disease Control and Prevention, contaminated birds can shed the virus of their saliva, nasal secretions and feces.
“We’ve acquired birds flying over us proper now, and it is exhausting to say the place they’re stopping and dropping off their contaminants,” Thompson stated. “It’s regarding. Our dairies are usually pretty open air.”
Still, Thompson discovered it “somewhat stunning” the virus has been found in cattle.
“There’s all of this proof from the final two years of what this virus can do,” Thompson stated. “We hope that this migratory season and no matter occurred that a few of this virus spilled over into cattle is a one-time occasion. But we won’t say that for positive.”
Because cows haven’t been broadly dying off from the illness, avian influenza in dairy cattle will not be thought of extremely pathogenic, Thompson stated.
But the signs of the virus are nonetheless obvious, she added.
“The actually large indicator is milk manufacturing drops fully,” Thompson stated. “Feed consumption goes down, and I feel water consumption has additionally been happening too. Of course, if these two issues go down, you get somewhat bit totally different manure consistency.”
There’s additionally herd-wide impacts to contemplate. The state veterinarian stated she’s heard of affected dairies briefly shedding milk manufacturing from 10% to 12% of their milk cows.
“These cows allegedly return into milk and so they return into the the manufacturing a part of the herd, however I do not know in the event that they return in producing the identical quantity of milk as they did earlier than they had been contaminated with the virus,” Thompson stated.

Producers are inspired to implement their biosecurity plans equivalent to limiting guests, separating new animals and sick animals, and cleansing pens, gear, autos, clothes, footwear, and palms, the discharge states.
Dairies are required to make sure solely milk from wholesome animals enter the meals provide chain. Additionally, something labeled as “milk” should undergo the pasteurization course of, which incorporates heating the contents to a excessive temperature to kill dangerous germs and pathogens.
“South Dakota Dairy Producers encourages all dairy producers to closely monitor their herd and contact their herd veterinarian immediately if cattle appear symptomatic,” Marv Post, Chairman of South Dakota Dairy Producers, acknowledged in DANR and AIB’s joint Thursday press launch. “USDA continues to emphasize that pasteurization kills the virus and that milk and dairy products are safe to consume.”
