South Dakota State University researchers lead the charge against new turkey virus threat
BROOKINGS, S.D. — South Dakota State University’s Animal Disease Research and Diagnostic Laboratory is taking a leading role in combating a new strain of avian metapneumovirus, a virus that is causing significant economic loss to the United States poultry industry.
Avian metapneumovirus, or aMPV, is an upper respiratory tract viral infection that affects all types of poultry but is most harmful to turkeys. The virus is divided into four different subgroups: A, B, C or D. While each subgroup can be found in different parts of the world, the U.S. has previously only experienced outbreaks of subgroup C.
In January 2024, SDSU researchers became the first in the U.S. to identify the first known case of aMPV subgroup B after testing a sample from an outbreak in a North Carolina turkey flock. Since then, the virus has continued to spread throughout the United States, wreaking havoc for poultry breeders across the country.

“A and B, were worldwide in Europe, South America and Asia, but never detected in the U.S.,” said Sunil Mor, assistant professor in the Department of Veterinary and Biomedical Sciences at South Dakota State University and section lead for virology at SDSU’s Animal Disease Research and Diagnostic Laboratory. “First time introduction of the subgroups A and B in the U.S., it’s a huge economic impact, especially on the turkey industry. The breeders are seeing up to 80% to 90% reduction in egg production.”
In Minnesota, which is home to a major portion of U.S. turkey production, the virus has made a significant impact. Ashley Kohls, executive director of the Minnesota Turkey Growers Association, said the Association started conducting surveillance on the virus last spring. From April to June, they found that nearly 100% of the turkey flocks in the state of Minnesota were impacted by aMPV.

“It’s unfortunate, and it’s massive,” Kohls said. “In addition to commercial turkeys or the meat birds, our breeder flocks are negatively impacted as well. For breeder birds, they have a significant reduction in the amount of eggs that they lay. Anytime you have breeder flocks impacted, there’s ripple effects, obviously, through the entire industry — less eggs, less poults, less birds, less turkey. It’s kind of been a rolling compound effect. There’s less baby poults, but then there’s also less birds coming out on the back end because of sick flocks.”
While the virus continues to cause issues for poultry producers, researchers at SDSU’s Animal Disease Research and Diagnostic Laboratory are working around the clock. Their quick identification of the virus was a game-changer.
“I remember the first meeting Dr. Mor confirmed that it was subtype B, people were actually not even able to believe that,” said Tamer Sharafeldin, an assistant professor Department of Veterinary and Biomedical Sciences at South Dakota State University and veterinary pathologist at SDSU’s Animal Disease Research and Diagnostic Laboratory. “But, within a week, the USDA confirmed that as well, and that was actually a leading discovery for South Dakota State University.”
With the virus confirmed, SDSU researchers pivoted to focus on vaccine development. They are currently working on three types of vaccines: a killed vaccine, a live attenuated vaccine, and a vector vaccine. The killed vaccine is the quickest to develop, as researchers can isolate the virus, inactivate it, and then test its safety and efficacy.
“We have isolated the virus, so we just inactivate it, test the safety potency, and then get the USDA approval to give it to the birds,” Mor explained.
The team is also working to improve diagnostic tools, however, vaccine development remains the highest priority.
“The process is not going to happen in a day or two. It’s going to take some time. We are actually competing with time to be able to achieve this,” Sharafeldin said. “We have produced the weakened virus — that’s number one. Number two, we are starting to establish the baseline needed for vaccine safety and efficacy.”

SDSU’s leadership in identifying the virus and developing solutions is vital not only for South Dakota but for the entire U.S. poultry industry.
“There’s a rapid need to develop vaccines for both the breeder flocks but also commercial turkey flocks as well. Developing that vaccine domestically will take some time, but there are a lot of folks working around the clock to make that happen,” Kohls said.
“South Dakota State University is not only the university that serves South Dakota citizens, it’s a university that leads research that would help the whole U.S. poultry industry in different states as well as it plays a very important role to enhance the U.S. economy,” Sharafeldin added.

South Dakota Republicans could be choosing from a crowded field when they make their choice for governor in the 2026 primary. With as many as five candidates in the race, would-be governors will need to find a way to distinguish themselves from the pack.
The first announced candidate for that race was Speaker of the House Jon Hansen, a Dell Rapids attorney. He declared his candidacy for the Republican nomination in April.
Hansen was the first candidate for governor to come from the new MAGA wing of the South Dakota Republican Party—referred to as “grassroots patriots” in his announcement speech. His campaign platform contains many of the topics his wing of the party has made a priority: cutting government spending, allowing school choice, protecting private property rights, opposing abortion and tightening election laws.
Another topic that Hansen touched on was ending “corporate welfare.” That’s the name he has given to the practice of using taxpayer dollars to boost private business. His example of corporate welfare gone bad was Tru Shrimp. The company was given a $6.5 million loan of state and local funds six years ago to build a facility in Madison. While the company did manage to change its name to Iterro, it has yet to break ground.
“I think it’s just unnecessary government mingling, and it’s risky business, and they’re wasting our taxpayer dollars to do it,” Hansen said in a South Dakota Searchlight story. “It’s the sort of stuff that we want to say ‘no more’ to. Let’s get back to the free market, low tax and low regulation.”
South Dakota got serious about using state dollars to entice and build business in 1987 when Gov. George Mickelson helped to create the Revolving Economic Development and Initiative Fund. Mickelson was able to convince the Legislature to implement a 1% sales tax increase that would sunset once it had raised $40 million for the REDI Fund. Since then the Governor’s Office of Economic Development has made loans and grants worth millions of dollars to new and existing businesses and industries in the state.
Taking state government loans and grants out of the marketplace would certainly be one way Hansen could approach his new role if he were elected governor. That tactic, however, fails to consider the fact that a financial boost from the state is sometimes what it takes to get the free market interested in investing in South Dakota.
Putting an end to low-interest government loans would certainly put the state at a disadvantage when it comes to competing with other states for business and industry.
A recent news release from the GOED showed just how invested the state has become in helping businesses grow. The news release noted a $3.4 million grant for the Big Stone Energy Storage Project thermal energy facility, a $2.6 million grant for a Bel Brands expansion and a $250,682 grant to Dakota Line Energy for a lagoon digester.
The news release said the grants would result in $419 million in capital expenditures and create 180 full-time jobs. In essence, the state is betting $6 million in hopes of getting a $419 million payoff. That kind of “government mingling,” as Hansen called it, seems to offer pretty good odds. It is, however, as he noted, “risky business.”
At its heart, investing in economic development will always be a bit of a gamble. That’s why we expect government officials to place safe bets, though there is always the chance for a bust like Tru Shrimp. That’s the nature of any gamble.
Hansen won’t be the only “patriot” in the Republican primary for governor, with Aberdeen businessman and political influencer Toby Doeden also declaring his candidacy. If “corporate welfare” is going to be an issue in the GOP primary, the people who like to use state loans and grants to boost their local economies have got to do a better job of telling about the benefits of government investment.
One way to do that would be to keep telling their story after the initial news release has been issued. Beyond the cliched photo of local officials with hardhats and shovels for a groundbreaking, taxpayers deserve regular updates on capital expenditures and job creation. This would add a layer of government transparency to the use of tax dollars. It would also soften the criticism from people like Hansen when an outfit like Tru Shrimp is slow to pay off on its state investment.
Politicians often like to tout the benefits of the “free market.” By curtailing state grants and low-interest loans, that market will be free to invest in states that are more financially welcoming.
In 1987, the state’s economy was badly in need of a jump-start, and it got one from Gov. Mickelson and the REDI Fund. Since then, that gamble has paid off more often than it’s gone bust. What Hansen calls “corporate welfare” has been a usually sound investment for South Dakota.
