Wild pigs are known carriers of at least 45 different parasites (external and internal) and
diseases (bacterial and viral) that pose a threat to livestock, pets, wildlife, and in some
cases, human health. Also of concern are foreign animal diseases (FAD): those that have never
been in North America or those that were present at one time but have been eradicated during the
last 100 years. FADs are of particular concern because they are highly contagious and the
continued expansion of wild pig ranges will only help to facilitate their spread if
The threat of disease transmission from wild pigs to other animals is probably of greatest
concern to the livestock industry. Several of these diseases are swine specific (both wild and
domestic), but others can affect cattle, sheep, goats, dogs, horses, and several species of
native wild mammals. Infectious diseases that are significant to livestock and other animals
Pseudorabies Virus (PRV)
Swine brucellosis (Brucella suis)
Bovine tuberculosis (TB)
African swine fever
Classical swine fever (Hog Cholera)
Foot and Mouth Disease
Diseases that are transmissible from animals to humans are called zoonotic diseases. Many of
these diseases are transmitted through contact with bodily fluids and handling or ingestion of
infected tissues. Diseases can also be transmitted indirectly through contaminated water sources
and possibly, through ticks. Zoonotic diseases transmissible by wild pigs include
Swine Influenza viruses
"An ounce of prevention is worth a pound of cure." Follow these simple measures to avoid
infection when handling or field dressing wild pigs:
Wear latex or nitrile gloves; pathogens can enter the body through cuts on hands or torn
Avoid splashing body fluids into your eyes or mouth.
Wash your hands thoroughly after field dressing and processing meat, even if you wear
Thoroughly clean and disinfect work areas and tools used to dress and butcher wild pigs.
Dispose of animal remains, used gloves, and other materials properly. Animal remains should
not be left for scavengers, nor should they be fed to dogs. Depending upon your
jurisdiction, several methods of appropriate disposal may be considered. Check with your
local health department or state wildlife agency.
Follow correct refrigeration, freezing, and cooking methods. Freezing to 0°F will render
bacteria inactive but will not destroy them; once thawed, bacteria can again become active.
Also, do not rely on home freezing to destroy Trichina and other parasites. Thorough cooking
will destroy all parasites and kill bacteria. Cook wild pork to an internal temperature of
165°F to 170°F.
