New swine virus found

iStock_000003693823Large_blogAs concerns about porcine epidemic diarrhea virus (PEDV) continue, officials in Ohio have found a new virus affecting pigs.

The new coronavirus, dubbed swine deltacoronavirus (SDCV), was detected in swine fecal samples from four different Ohio pig farms. The farms had each experienced an outbreak of diarrheal disease beginning in January and early February. Symptoms were similar to those caused by PEDV and transmissible gastroenteritis (TGE), both of which also are coronaviruses.  The virus is not transmissible to people and isn’t a risk to the food supply, according to a statement from the Ohio Department of Agriculture (ODA). A similar virus was found in Hong Kong in 2012.

The new virus was detected by Dr. Yan Zhang, a virologist with ODA, through polymerase chain reaction (PCR) testing on samples from one of the farms, which showed the virus was not PEDV or TGE. Additional samples from the other three farms tested positive for PEDV and SDCV. ODA is working to determine if SDCV was the cause of the diarrheal disease on the affected farms.

The discovery comes as the swine industry is combating PEDV, which was first reported in the U.S. last spring and has since spread to Canada. Although PEDV isn’t transmissible to humans and doesn’t affect food safety, its high mortality rate is of great concern for swine producers.
