Feral Hog Disease Information

Hog Diseases:

Feral hogs can carry a number of diseases, the most common being pseudorabies and swine brucellosis.  Of these two diseases, swine brucellosis warrants particular concern because an infected hog can transmit the disease to humans.


Brucellosis is a bacterial infectious disease of animals and humans caused by members of the Genus Brucella.  The effects of the disease in the primary host caused by the various species of Brucella are generally limited to abortions and reproductive organ infections.  In other host species such as humans, the disease clinically may mimic severe flu and may vary to crippling arthritis or meningitis.  There is no cure for brucellosis in animals and humans are treated with very high doses of antibiotics for extended periods to hopefully clear the infection.  Animals and humans are exposed to the Brucella bacterium by handling or contact with infected placentas, amneonic fluids, vaginal discharges, milk semen, reproductive tissues, and exudates from infected animals usually just prior to and after an abortion.


Pseudorabies , a viral disease, attacks the central nervous system and can be fatal to cattle, horses, goats, sheep, dogs, cats, raccoons, skunks, opossums and small rodents.  It is not related to rabies and it does not infect humans.  The spread of PRV from feral swine to domestic cattle has been observed on multiple occasions in Florida and Texas.  Contamination by feral swine of supplemental feed spread on the ground for cattle is suspected as the source of infection.


Anthrax is a soil-borne disease that occurs irregularly in Texas, usually where the daily minimum temperature is at least 60 degrees F, where wet periods are followed by long dry periods, and where soils are alkaline or neural.  All mammals, especially ruminants, are susceptible to anthrax.  Humans can contract the disease from contaminated soil or animals.  Vaccines are available for both humans and livestock.


Foot and mouth disease is a foreign animal disease of great concern because it is highly contagious, spreads rapidly, can cause serious economic losses, and can constrain international trade in livestock products.  It does not affect humans, but humans can spread the virus. There is no known cure .
Livestock should be vaccinated appropriately, especially if they may have contact with feral hogs.


Hog diseases that could have severe repercussions for agribusiness include swine brucellosis, pseudorabies, leptospirosis, tuberculosis, tularemia, trichinosis, plague, anthrax, hog cholera and swine vesicular disease.
Feral hogs are susceptible to a variety of infectious and parasitic diseases.  The more hog populations increase and expand, the greater the chances that they may transmit diseases to other wildlife, to livestock and to humans.
