Eight years of extensive research, including work at Kansas State University, has led to a disquieting scenario for swine producers: Feed and feed ingredients could potentially serve as means for the introduction and transmission of foreign animal diseases of swine.

 

Megan Niederwerder, assistant professor of diagnostic medicine and pathobiology in the College of Veterinary Medicine, recently published an overview on the significance of the collective feed research related to swine viruses and specifically to African swine fever virus. "Risk and Mitigation of African Swine Fever Virus in Feed" was published March 18 in the journal Animals. Research funding was provided by the National Pork Board.

 

"Since the 2013 introduction of porcine epidemic diarrhea virus into the United States, researchers have investigated the potential role of feed and feed ingredients for the transboundary spread of swine diseases," Niederwerder said. "Feed ingredients are commodities traded worldwide, and the U.S. imports thousands of metric tons each year from countries where circulating foreign animal diseases have been identified."

 

African swine fever, or ASF, is the most significant foreign animal disease threat to U.S. swine production, Niederwerder said. The primary goal of negative countries, such as the U.S., is to prevent ASF entry as there are no vaccines or treatments available...
