The U.S. Department of Agriculture (USDA) has issued an order requiring pork producers, veterinarians and diagnostic laboratories to report new incidents of porcine epidemic diarrhea virus (PEDv) and porcine deltacoronavirus to state health officials or USDA’s Animal and Plant Health Inspection Service. The order formalizes measures announced in April to combat the spread of PEDv, which has killed some seven million piglets since it was identified in early 2013. USDA also announced $26.2 million to fund a variety of activities to combat the diseases and support affected producers, including vaccine development, state management and diagnostic testing. More information on the April announcement appears in Issue 521 of this Update.
