Pathogens from wild feral pigs

Diseases

 


Feral hogs (wild pigs) are susceptible to a wide range of viral, bacterial, and fungal diseases such as:

  • African swine fever 
  • anthrax 
  • tuberculosis
  • brucellosis
  • hog cholera
  • E. coli
  • foot-and-mouth disease
  • influenza viruses
  • leptospirosis
  • pseudorabies virus
  • vesicular stomatitis

  

Specifically, feral hogs have the potential to contract and transmit all of the diseases of domestic swine.  Some of these diseases are specific to domestic swine, while others can also infect other wild and domestic mammals as well as humans.

Three men from the SF Bay Area were diagnosed with leptospirosis last week. The men were all in their 30's and were previously healthy. Their symptoms began May 16-17 with fever, headache, and myalgias. One patient developed hepatitis and another renal failure; two were hospitalized. Leptospira-specific IgM was positive in 2 of the 3 patients; the 3rd patient's serum may have been collected too early in the course of the disease to turn positive. Additional tests including convalescent serology and serotyping are pending. The only common exposure for those patients was on May 6-7 when they rented a houseboat on a reservoir in the Sierras with five other men. While everyone reported swimming in the reservoir, only these three patients swam to a cove and hiked up to a waterfall. Wildlife is common in this area and range cattle were observed grazing above the cove where a tributary drains into the reservoir. DHS will be assisting the local health department with environmental sampling at the cove, including collection of water specimens to test for Leptospira.


Wild pigs are; large powerful animals, smart, strong, few natural enemies, destructive, potentially they can carry dangerous pathogens, roaming territories and prolific breeders.  I strongly suggest that you do not confront wild feral pigs they are dangerous and when piglets are present the sows (mother) can be very dangerous.  The tusks that pigs have can tear human flesh in the blink of an eye.
