Custom Manure Applicators Asked to Help in Preventing the Spread of Pig PED Virus

Larry D. Jacobson, Extension Agricultural Engineer, U of M Extension

With the harvest season fast approaching, the application of stored manure from animal facilities on the harvested fields will soon follow. This year, pork producers need to be aware of the risk of spreading Porcine Epidemic Diarrhea (PED) through equipment used to pump and land apply manure from all farms but especially those with pigs exhibiting clinical signs of the disease. PED can be spread through oral-fecal contact, manure contaminated boots, clothing, birds and wildlife, transport trailers and other equipment.

PED is a viral enteric swine ONLY disease with clinical symptoms of diarrhea, fever, vomiting, and death (age dependent). PED was first detected in the United States this spring and as of the first of September the disease had been confirmed on more than 500 swine herds in the United States. Spread of the virus continues, and it is both a good animal husbandry practice and a good neighbor policy for all pork farmers with pigs exhibiting clinical signs of PED to obtain a confirmed diagnosis and immediately establish enhanced biosecurity practices to avoid spreading the virus within their own animals and (or) to neighboring swine herds.

Because many pork producers hire commercial manure applicators to pump and land apply their manure from a farm's storage pits, tanks, and/or basins, their equipment can easily spread this virus from infected farms (barns) to uninfected farms (barns). In response to this urgent concern, the National Pork Board (NPB) along with several midwestern universities (Michigan State, Iowa State, and Minnesota) have just released a one page fact sheet listing the biosecurity recommendations that commercial manure haulers should follow to reduce the risk of spreading this virus.

The fact sheet emphasizes the need for the manure applicator to communicate closely with the pork producers when pumping manure on a farm to reduce the risk of transferring this virus by manure handling equipment either from or to the farm.
