Concerned over the spread of of Porcine Epidemic Diarrhea virus (PEDv) in U.S. pig populations, Russia announced last week it was suspending U.S. imports of live pigs effective May 30, Reuters reports. The disease has already killed roughly 10 percent of the U.S. pig population and is reportedly spreading across other countries such as Mexico, Canada, China and Japan. Russia’s move is intended to prevent the spread of the disease into that country, which has thus far not been affected. The virus is not considered a food safety issue with pork and cannot spread to humans, according to the U.S. Department of Agriculture. PEDv has been found in European countries since 1971. The strain currently affecting U.S. pig populations appears to be related to a strain found in China in 2012. Because an Indiana farm recently experienced a second PEDv outbreak, experts predict it could be harder than expected to contain. According to the U.S. National Pork Board, PEDv is not considered a trade-restricted disease. Russia is one of the top importers of live pigs from the U.S., along with China and Mexico. China reportedly suspended importation of live U.S. pigs earlier this spring.
