Subject: SWINE PEDV DETECTED AT GA JR NATL SWINE SHOW --CRITICAL IMPORTANCE - PLEASE READ!!!!!
Agents and Teachers -- Please forward to ALL swine Exhibitors.
Two sets of samples from the Jr. Natl. Swine show were submitted to the Diagnostic lab earlier this week. The first set, from the scales and wheel barrows came back negative for PEDv as was reported earlier in the week. However, the second set of swabs taken directly from pigs that were exhibiting symptoms, were reported this morning as being POSITIVE for the PED variant of the pan-Coronavirus. It is absolutely critical that we do everything possible to keep this disease from spreading throughout the state and protect any pigs that have not been exposed to the disease from exposure. Below you will find the information you need to help to prevent the spread of this disease. Failure to contain this disease within the state will have a devastating effect on the swine industry in Georgia.
What is PEDv:
PEDv is a Coronavirus related to TGE
It was first confirmed as being in the U.S. in May of 2013 and these are the first reports of it being in swine in Georgia.
PEDv infects only pigs. It does not infect other livestock or humans and has NO effect on meat or meat quality. It is safe to consume pigs that have had PEDv.
Clinical Signs of PEDv:
Severe diarrhea in pigs of all ages.
High mortality rates (100% in preweaned pigs)
Incubation Period of PEDv:
12-24 hours after initial exposure. Pigs get sick very quickly after initial exposure.
Shedding Period of PEDv:
Pigs will shed the virus for at least 3-4 weeks after all symptoms have passed and this period may be much longer. Pigs that are shedding the virus can give it to other pigs. Just because your pig has stopped exhibiting symptoms does not mean that it is safe to co-mingle it with other pigs that have not been exposed to the virus.
How is PEDv spread:
PEDV is spread via fecal to oral contact. Pigs only have consume a very few virus particles to become infected (I have heard as few as 10).
The disease is most often spread by infected manure on boots, trucks, trailers, clothing, and other pieces of equipment that are used around the farm as well as from pig to pig.
What to do if you suspect your pig has PEDv:
Quarantine your herd (this is not mandatory, but highly recommended). Be safe and don’t take the risk of exposing someone else’s pigs to this disease.
CONTACT YOUR VETERINARIAN. – It is critical that we get a confirmed diagnosis from the lab.
PEDv is a reportable disease to USDA, so all cases need to be reported to your local Veterinarian. Local Veterinarians have/will receive information as to how to handle these cases.
Treatment of pigs with PEDv:
As with any viral infection, the only real treatment is to treat the symptoms. Keep pigs warm and dry and give them lots of water. Electrolytes may be beneficial.
There are a couple of approved vaccines, but these need to be given prior to exposure.
Prevention of the spread of PEDv:
Isolate all show pigs returning from a show from the rest of the herd for at least 3 weeks (6 weeks is better). Feed and care for the isolated pigs after you have taken care of all other stock. Do not move back and forth between the isolated stock and the healthy stock. After caring for isolated stock, change clothes and boots and shower before going back to care for healthy stock.
If your pigs or any pigs that your pigs have had contact with have or have had any symptoms of the disease, do not take your pigs to any other shows or exhibitions. Leave them at home until the isolation period has passed. Do not risk spreading this disease to other pigs.
Clean and disinfect everything that went to the show or that comes in contact with a sick pig. This includes everything in the show box, water buckets, pen dividers, herd boards, trucks, trailers, feed buckets, boots, wagons, show sticks. If it went to the show it needs to be scrubbed to remove all organic matter, and then disinfected. PEDV is susceptible to Clorox, Virkon S, TekTrol, and 1 Stroke Environ. Make sure everything is allowed to completely dry before using it. Drying in the sun is best.
Institute a strict biosecurity policy on your farm. Do not allow visitors. Require everyone entering the farm to wear clean, farm issued clothes and boots. Do not wear boots or clothes that you will wear on your farm to other farms or any place there are other pigs. If you must visit another farm or a stock yards or any place where other pigs are present, take a shower and put on clean clothes and shoes before entering your farm. Pay close attention that you do not track manure from place to place on the floor mats of your vehicle. Make is a habit to wipe down steering wheels, door handles and other places when your hands could spread the disease with disinfecting wipes.

PEDv has the potential to totally devastate both the commercial and the show pigs industries in Georgia. It is imperative that everyone do their part in the prevention of the spread of this disease. Please be responsible and do your part in the prevention of the spread of this deadly disease.
