USDA federal order requires reporting of PEDv

Farm Forum

ST. PAUL, Minn. — Producers and veterinarians must report porcine epidemic diarrhea virus (PEDv) and porcine deltacoronavirus (PDCoV), according to a new federal order from the U.S. Department of Agriculture.

Producers who suspect their pigs have PEDv or PDCoV should work with their veterinarian to diagnose, report and manage the virus.

The federal order has two basic requirements:

1. Producers, veterinarians and diagnostic laboratories are required to report positive occurrences of PEDv, PDCoV or other novel swine enteric coronavirus diseases (SECD) that meet the case definition. An occurrence may be the initial detection or a reoccurrence.

In Minnesota, reports should be directed to the Minnesota Board of Animal Health. If samples are sent to the University of Minnesota Veterinary Diagnostic Laboratory (VDL) for testing and are found to be positive, duplicate reporting by herd owner, veterinarian, and others with knowledge of the disease is not required. The VDL is a National Animal Health Laboratory Network lab, which is required to report positive SECD cases.

2.) Producers 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.

When reporting an SECD case, the following information must be submitted by the veterinarian and lab performing the diagnostic testing:

• Premise identification number (PIN)

• Date of sample collection

• Type of unit sampled (sow, nursery, finisher)

• Test methods used to make diagnosis

• Diagnostic test results

Producers reporting SECD must work with their herd veterinarian, state or USDA veterinarian to develop and implement a herd management plan that addresses the following:

• Biosecurity of visitors and vehicles entering or exiting the premises

• Monitoring employee biosecurity

• Periodic herd health observation

• Animal movement (both into and out of the herd)

• Cleaning and disinfection of facilities

• Diagnostic testing to monitor the status of the herd infection and assess effectiveness of control strategies

• Maintaining records on pig movement that are accessible to state or federal animal health officials upon request

Herd owners failing to report a case or to follow a herd management plan may be subject to civil penalties and may have additional requirements placed on their premises by state and federal animal health officials.

The Minnesota Swine Health Advisory Committee has taken an active role in determining the most efficient and cost-effective way to comply with the federal order. The committee is made up of swine producers and veterinarians, and representatives from the VDL, Minnesota Pork Board, and Minnesota Board of Animal Health.

These viruses are only infectious to pigs and are not a food safety concern.

PEDv first was confirmed in the United States in May 2013. In recent months, PDCoV, an additional related virus, has appeared in this country. Both viruses can cause severe diarrhea and vomiting, resulting in dehydration, especially in young piglets. Dehydration has been known to cause high mortalities in piglets less than seven days of age.

Secretary of Agriculture Tom Vilsack issued the federal order on June 5 in response to the negative impact PEDv and PDCoV are having on the U.S. pork industry.
