Porcine Epidemic Diarrhea Virus (PEDv)

PEDv Confirmed in Georgia

The Georgia Department of Agriculture has reported a known case of Porcine Epidemic Diarrhea virus (PEDv). This is the first known positive to be found in Georgia. Results from two samples from pigs at the Georgia Junior National Livestock Show held February 18-21, 2015 tested positive for PEDv on February 27, 2015.

What is PEDv?

Porcine Epidemic Diarrhea Virus (PEDv)

Porcine Epidemic Diarrhea (PED) is a viral disease of swine that is associated with fever, severe diarrhea and vomiting. The disease is highly contagious and is caused by a Coronavirus. PED mimics a common pig disease called Transmissible Gastroenteritis (TGE), which is also a Coronavirus, only lab tests can tell the difference. PED is not a zoonotic disease (it does not affect people), does not affect any other domestic species and is not a food safety concern.

The disease is most severe in young piglets, but can affect pigs of any age. The disease can cause death and loss of production. Introduction of PEDv into a swine herd with no previous exposure to the virus typically results in acute outbreaks of abortion, severe diarrhea, vomiting, high morbidity (often 100%) and variable mortality (as high as 100% in young pigs less than 3 weeks of age). The incubation period is short (3-4 days) and natural immunity develops. Pregnant sows often abort due to fever; however, older pigs usually recover from the disease within 7-10 days. PEDv can be spread in several ways. The fecal/oral route (virus in the fecal matter of affected pigs is ingested by healthy animals), fomites (inanimate objects such as equipment (trailers, chutes, buckets and waterers), clothing, boots and contaminated feed have all been shown to spread the virus. The virus is very hardy and can survive for long periods of time especially in cold damp weather.

Currently, there are two vaccines available. Vaccination is recommended in exposed herds, but has not been shown too effective in naïve herds. There is no specific treatment; however, supportive therapy is useful in the treatment of older animals and sows that have recovered from the disease pass immunity to their offspring. Recovered animals can shed the virus for up to a month after recovery.

A very strict biosecurity program is the only way to prevent introduction of the virus. Very thorough cleaning and disinfecting of trailers and equipment are essential to keeping the virus out. The creation of a “Clean Crossing Line” will help to prevent contaminated personnel or products from entering the farm.

PED exists in many parts of the world. The disease is very common in China, Korea and other Asian countries. In May 2013, the disease was first diagnosed and confirmed in the USA, in Iowa. It is currently unknown how the virus entered the US. There is some concern that feed products such as porcine plasma products sprayed on pellets in certain rations has been responsible for introduction or spread of the disease. PED is not a listed disease of the World Organization for Animal Health (OIE); is not considered a Foreign Animal Disease in the United States; and there are currently no international or interstate trade restrictions pertaining to PED in U.S. swine.

PEDv is reportable. Confirmed disease and suspected disease should be reported to the Georgia Department of Agriculture at http://agr.georgia.gov/animal-health.aspx. You may also call Animal Industry Division, Animal Health at 404-656-3667 or the State Veterinarian at 404-656-3671.

The disease has spread to 28 states across the United States and to Canada causing millions of dollars of damage due to losses from abortions, mortality and poor feed conversion. All hog farmers are encouraged to monitor the Georgia Department of Agriculture website, www.agr.georgia.gov , for news and updates on PED.

Veterinarians can send samples to our state diagnostic lab for confirmation of PEDv:

02/12/15 - USDA issues Swine Enteric Coronavirus Disease (SECD) Situation Report

In response to the significant impact porcine epidemic diarrhea virus (PEDv) and porcine deltacoronavirus (PDCoV) are having on U.S. pork producers, the United States Department of Agriculture (USDA) today announced $26.2 million in funding to combat these diseases. Additionally, USDA issued a Federal Order requiring the reporting of new detections of these viruses to its Animal and Plant Health Inspection Service (APHIS) or State animal health officials...

BIOSECURITY FOR PED

So what can you do to decrease the chance of your herd becoming infected with PED? First and foremost, review and tighten your biosecurity protocols. Be diligent about personnel and visitors but also consider supplies, feed ingredients, food items, etc. that might be of international origin. If you are unsure about the origin of a particular product, or the components of a product, contact the supplier and request information on the origin of their ingredients or components. Contact your Georgia Pork Board and National Pork Board.

Additional biosecurity recommendations should include:

  • Limiting traffic (people, vehicle, trailers and equipment) onto the farms
  • Thoroughly cleaning and disinfecting anything coming onto the farm
  • Enforcing downtime requirements and maintaining a log of visitors
  • Properly disposing of dead stock
  • Isolating newly arriving animals and continuing vet to vet discussions about animal health at the herd of origin
  • Showering into the facility where practical and changing into clean boots and coveralls (veterinarians should also be careful not to track the virus between herds on their person, equipment or vehicles).
