Farm Groups in Canada are blasting U.S. truck washes for being too dirty to prevent the spread of Porcine Epidemic Diarrhea virus. This comes as three farms in Canada discovered the virus in the past two weeks. Last month, Canada revived a requirement that trucks delivering pigs to U.S. farms be washed before returning home. The recent infections are fueling concerns among Canadian farmers and veterinarians that commercial U.S. truck washes are contaminated with the virus and raising the risk for outbreaks, according to Reuters. However, there is no proof linking U.S. facilities to the latest cases. Manitoba Pork general manager Andrew Dickson simply said "we have our deep, dark suspicions." The problem with commercial washes, according to Canadian farm groups, is that some use recycled water, which can spread diseases, and others do not heat trucks enough to kill viruses.
