State Vet Encourages Livestock Show Managers to Observe Strict Biosecurity
Dr. Richard Wilkes, state veterinarian with the Virginia Department of Agriculture and Consumer Services, announced this week that Virginia has just received laboratory confirmation of its first case of porcine epidemic diarrhea virus, or PEDV. In light of this case, which coincides with the beginning of the exhibit season for 4-H members, FFA students and other livestock exhibitors, Dr. Wilkes says strict biosecurity is the most effective and most practical way to prevent the spread of PEDV and many other livestock and poultry diseases.
Wilkes encourages every person involved in showing livestock to enhance their biosecurity efforts.
“We always urge livestock owners who show animals and managers of show and exhibition facilities to keep biosecurity uppermost in their minds,” Wilkes said, “but with swine, it is even more important now that Virginia has experienced its first case of PED. Good biosecurity can help keep the disease from spreading.”
Anytime animals are co-mingled at events, there is a risk they may be exposed to an infectious disease agent. Some states have canceled preshow weigh-ins or other animal events to try to prevent PEDV infection of swine. Virginia show managers may want to consider voluntarily canceling some of the higher risk activities.
The virus is highly contagious and commonly spreads through pig manure. Consuming pork continues to be safe and the disease does not affect humans, but is often deadly to piglets. Practicing and implementing sound biosecurity measures is critical in keeping the state’s animals disease-free and marketable.
Equine herpes virus is another highly contagious disease that has caused disease and death at multiple equine events across the country recently.
Wilkes says that good biosecurity and advance planning will reduce the chances of spreading an infectious disease. Show managers should have a proper biosecurity plan ready to execute in the event that an animal disease is introduced at a major stock show or event.
The department offers the following guidelines to help minimize risk at events where animals co-mingle. These general recommendations also apply to diseases that can be spread between humans and animals.
Biosecurity for Animal Exhibitors
Consult your veterinarian to establish an appropriate vaccination program for your livestock prior to attending an event.
Before stalling your animal at an event, make sure the stall has been cleaned and disinfected, and use clean, fresh bedding.
Minimize direct contact with other animals.
Use your own water and feed buckets. Avoid letting your animal drink from a communal water trough. Fill water buckets from a faucet, not a shared tank.
For equines, do not share grooming equipment or tack. If you must, wash and disinfect it before returning to your own animal.
Wash your hands thoroughly after handling other animals to minimize the risk of transferring a disease back to your animal.
Before returning home from an event, clean and disinfect your equipment — boots, tack, grooming supplies, buckets, etc. — to help reduce the risk of transporting an infectious agent back home.
Isolate your returning animal for two weeks or prevent contact with your other animals, and watch for signs of illness in all of your animals.
When you come home from a fair/exhibition, be sure to disinfect your trailer.
Consult your veterinarian concerning these and other steps you can follow, which may reduce the risk of your animal acquiring an infectious disease while traveling.
Biosecurity for Event Organizers
Minimize contact between animals where possible.
Minimize spread by human hands — limit public access, provide hand sanitizer, establish restricted areas in front of stalls and trailers, post hand-washing signs.
Minimize spread by shared tack — post signs advising participants not to share equipment.
Where practical, provide solid, high-walled stalls to minimize spread of infectious nasal droplets.
Biosecurity When Visiting a Fair
Locate hand-washing stations and use them often. Always wash your hands after petting animals or touching the animal enclosure, especially before eating and drinking.
Use running water and soap whenever possible. Use hand gels if running water and soap are not available.
Keep food and drinks out of animal areas.
Never allow children to put their hands or objects, such as pacifiers, in their mouths while interacting with animals.
