Subject: Precautions needed to prevent Porcine Epidemic Diarrhea Virus from coming to Georgia

Heather, Tommy,

 

Dr. Reeves and I have developed the information below in an effort to prevent the spread of PEDV into Georgia.  Would you please forward it to all appropriate lists and to anyone else you think appropriate.

 

Precautions Needed to Prevent Porcine Epidemic Diarrhea Virus (PEDV)

 

As you may be aware a number of cases of PEDV have been diagnosed in the Midwestern United States. To date, there have been no cases diagnosed in Georgia; however there have been cases diagnosed as close as North Carolina.  Porcine Epidemic Diarrhea Virus has previously been reported in a number of countries across the globe, but 2013 is the first time it has been found in swine herds in the United States.  At this time researchers have not determined how it entered the country.  The disease is spread fecal-oral and can easily be spread by farm visitors and transport vehicles.  This virus does not affect humans.

 

With the swine show season just around the corner, many exhibitors, parents, agents and teachers will be traveling to the Midwest to pick up show animals.  It is important that prior to entering any farm that the producer be asked about the farm’s PEDV status and what biosecurity precautions the producer is taking to insure that the farm does not become infected.  Do not be surprised if many producers limit access to their farm.  It is recommended that you do not enter any farm or purchase pigs from a farm that has had a diagnosed case of PEDV in the past 90 days.  While the duration of the virus shedding post-infection is unknown, it is assumed that this virus will be shed by pigs for up to 100 days, similar to TGE. 

 

PEDV is spread quickly from pig to pig by the fecal-oral route.  Any exposure to manure from an infected pig can result in the spread of the disease.  Producers and transporters need to be very careful to avoid spreading the disease via contaminated clothes and transport vehicles.  Transport trucks and trailers should be washed to remove all organic matter, disinfected, and dried after every trip, even if no animals were transported. PEDV is susceptible to Clorox, Virkon S, TekTrol, and 1 Stroke Environ.  Manure on tires, mud flaps or in the trailer can spread the disease very quickly.  All clothing worn on the trip should laundered prior to being worn on the farm.  All purchased animals should be isolated for at least 2 weeks and watched carefully for any symptoms of the disease.

 

Symptoms of PEDV range from watery diarrhea and vomiting in nursing pigs to transient (intermittent) diarrhea and off feed in finishing animals.  Most pigs within a production system will show some symptoms of the disease and death loss can be has high as 50-100% in pigs under 3 weeks of age.  PEDV looks very similar to TGE and requires a laboratory diagnosis to confirm its presence.  If you observe diarrhea in pigs on your farm, please call your local veterinarian immediately for a diagnosis. Current treatment recommendations are very similar to the recommendations for TGE.   

 

It is important to both the swine industry in the state of Georgia and for the swine shows in Georgia that we do everything possible to keep this disease out of the state.  Everyone working with swine in the state needs to be extremely vigilant and follow biosecurity recommendations to help prevent the disease being spread to Georgia.  If you suspect you have a pig on your farm that has the disease, you need to call your veterinarian immediately for a diagnosis.  Any pig that is suspected or confirmed as having PEDV should not be transported off the farm for any reason until they are symptom free for at least 90 days.
