Anytime there is a congregation of swine, especially swine originating from different premises, there is an increased risk for the spread of diseases such as Porcine Epidemic Diarrhea (PEDv), Porcine Reproductive and Respiratory Syndrome (PRRS), influenza, and others.
Establishing and following sound biosecurity practices is the cornerstone for reducing the risk of spreading these diseases. Swine owners are encouraged to follow these biosecurity recommendations to reduce the risk of disease exposure and transmission.

African Swine Fever
African swine fever is a highly contagious and deadly viral disease affecting both domestic and wild pigs of all ages. ASF is not a threat to human health and cannot be transmitted from pigs to humans. It is not a food safety issue.
ASF is found in countries around the world, particularly in sub-Saharan Africa. More recently, it has spread through China, Mongolia and Vietnam, as well as within parts of the European Union. It has never been found in the United States
African Swine Fever is a reportable disease to the Texas Animal Health Commission.

Swine brucellosis is caused by the bacteria Brucella suis, and is closely related to Brucella abortus, which causes brucellosis in cattle. Texas is currently considered Swine Brucellosis free for large "commercial" herds, although infection continues to be found at times in smaller backyard herds. In these instances, infection is usually the result of exposure to feral swine. Swine Brucellosis is known to be prevalent in Texas's feral swine population.
Swine Brucellosis is a reportable disease to the Texas Animal Health Commission.

Pseudorabies, also referred to as "Aujeszky's Disease", was identified by Dr. Aladar Aujeszky in Hungary in 1902. Pseudorabies is a highly contagious, economically significant disease found in swine. This herpes viral infection causes central nervous system (CNS) signs and high mortality rates in young swine and respiratory illness in older swine. Swine are the natural host for this disease and are the only animals to become latent carriers. Feral swine are considered a natural reservoir in Texas, and may be asymptomatic.
Pseudorabies is a reportable disease to the Texas Animal Health Commission.
Porcine Epidemic Diarrhea Virus (PEDv)
PEDv is an emerging viral disease of concern to the U.S. swine industry causing severe diarrhea and high mortality in young pigs. The virus is found in manure and can be transported on contaminated trucks or trailers. It is not anticipated to be a disease of regulatory concern at this time, but state and federal animal health officials are assisting the swine industry with the epidemiological investigations and outreach about the disease. It does not affect humans or compromise food safety. There is no known treatment so an emphasis on establishing strong biosecurity measures is critical to minimize further spread.
Feral swine carry diseases that pose a threat to domestic swine, cattle, humans, and other species. Historical test data indicates that about 10 percent of feral swine are infected with Swine Brucellosis, a disease that affects cattle and occasionally humans. Approximately 20 percent of feral swine may be infected with Pseudorabies (PRV) unrelated to rabies, but causes illness in hogs and affect market ability of domestic swine.
In 2007, the 80th Texas Legislature provided that the TAHC regulate the movement of live feral swine as a measure to control the spread of disease. The TAHC subsequently passed rules that allow feral swine to be captured and sold for slaughter, while still protecting domestic swine and other livestock from the disease risks posed by these animals.
Approved Feral Swine Holding Facilities
An Approved Holding Facility for feral swine is a pen or pens approved by the TAHC to temporarily hold feral swine pending movement to a recognized slaughter facility or an authorized hunting preserve.
Feral swine can be legally moved only from the premises where trapped to either an approved holding facility (as listed below), a recognized slaughter facility, or an authorized hunting preserve.
Purchase of Feral Swine
- Approved feral swine holding facilities may purchase trapped feral swine.
- TAHC is not involved in any aspect of the purchase transaction
- Purchase price is at the discretion of the individual facility owner.
