Venomous snakes found in the United States include rattlesnakes, copperheads, cottonmouths/water moccasins, and coral snakes. They can be dangerous to outdoor workers including farmers, foresters, landscapers, and any other workers who spend time outside. Although rare, some individuals with a severe allergy to snake venom may be at risk of death if bitten. It has been estimated that less than 5 people die in the United States die from venomous snake bite. The number of deaths would be much higher if people did not seek medical care. It is important for individuals to train themselves about their risk of exposure to venomous snakes, how they can prevent and protect themselves from snake bites, and what they should do if they are bitten.


FACT - Rattlesnake venom will break down blood. A snakes venom can also paralyze the nerves of the prey, which help subdue its prey, which is actually the very beginning of the digestive process.
