Porcine epidemic diarrhea is a virus that causes significant sickness in swine, affecting their growth and health, and causes high mortality in piglets.

The disease is common in parts of Asia and Europe but is not reportable to the World Organization for Animal Health.

PED only affects pigs and is not a food-safety concern.

The U.S. Department of Agriculture confirmed the presence of PED in this country May 16, 2013. As of April 5, more than 5,500 cases have been confirmed in 28 states.

Because PED is a persistent disease that is continuing to spread across the country, USDA is instituting a monitoring and control program. A federal order requires mandatory reporting of all herds diagnosed with PED. Animal health laboratories receiving diagnostic samples are also required to provide positive tests and location information to USDA.

USDA's Animal and Plant Health Inspection Service (APHIS) is part of a task force that aims to investigate PED, identify and trace risk factors in the transmission of the disease and keep producers informed. The task force has established testing protocols, sequenced the virus and conducted two feed investigations.
