The virus is a coronavirus, which damages the cells lining small intestine of a pig, reducing the absorptive surface, It is thought the virus may have spread through pig feed. US cases of the virus have also increased, the United States Department of Agriculture reported that the virus had occurred in 26 states, with 5,000 reported cases.
Some US officials say the US outbreak can be traced back to China where the virus broke out in 2010. As a result of this US outbreak, China and Japan have restricted pork imports from the US until they can prove hogs have been pre-tested for PEDV.
The US National Pork Board (NPB) recently held a collaborative meeting with Canadian officials from the pork and feed agencies. Speaking at the meeting Paul Sunberg DVM, vice-president of science and technology at the NPB said: "After taking all of this information into consideration, the group agreed that there are multiple ways for pigs to become infected via a faecal-oral route, including environmental, transportation, feed systems and other vectors.
"If feed is a factor in the transfer of PEDV, based on past research we know there are specific time and temperature combinations that should inactivate the virus," added Sunberg.
