Swine Enteric Coronavirus Diseases (SECD), including Porcine Epidemic Diarrhea virus (PEDv)

Since its appearance in the United States in April 2013, porcine epidemic diarrhea virus (PEDv) has spread within the swine industry.  In recent months, an additional related virus, porcine delta coronavirus (PDCoV), has appeared in this country.  Infections with these novel swine enteric coronavirus diseases (SECD) can cause significant morbidity and mortality, particularly in young piglets.

What is USDA doing about SECD?
In response to the significant impact swine enteric coronavirus diseases (SECD), including Porcine Epidemic Diarrhea virus (PEDv) and Porcine deltacoronavirus (PDCoV), are having on the U.S. pork industry, USDA issued a Federal Order on June 5, 2014.  USDA, States, herd veterinarians and producers will collaborate to manage the diseases in a manner that supports business continuity for commercial pork producers and maintains a plentiful supply of pork for consumers.

There are two basic requirements of the Federal Order.  First, producers, veterinarians, and diagnostic laboratories are now required to report all cases of new SECD, including PEDv and PDCoV, to USDA or State animal health officials.  Second, operations reporting these viruses must work with a veterinarian – either their herd veterinarian, or USDA or State animal health officials – to develop and implement a reasonable management plan to address the detected virus and prevent its spread.

What can I do about SECD?
Producers, veterinarians and laboratory personnel are required to report SECD affected herds, effective June 5, 2014.

To help prevent SECDs, including PEDv, you should always follow good biosecurity practices.

If you have an SECD-positive herd, you will need to complete a herd management plan.
