What is a venomous (poisonous) snake bite?

A venomous (poisonous) snake bite is a bite or a puncture wound made by a snake that is capable of injecting, secreting, or spitting a toxin into the penetrated skin wound or, mucus membranes or the eyes where the toxin can be absorbed. In North America, there are about 25 species of snakes able to secrete toxin. However, non-native poisonous species are present in zoos and held in private homes or other areas by snake collectors. Consequently, almost any type of venomous snake bite can be encountered in the US. About 7,000 snake bites are reported in the US per year, but because snake bites are not required to be reported, it is estimated that up to 45,000 bites per year may occur with about 8,000 by poisonous snakes. The most common venomous snakes in the US are rattlesnakes, copperheads, cottonmouths/water moccasins, and coral snakes.

What is a nonvenomous (nonpoisonous) snake bite?

A nonvenomous (nonpoisonous) snake bite is a bite or puncture wound made by a snake that is incapable of secreting a toxin. This should be distinguished from a dry bite. A dry bite is a bite by a venomous snake that does not inject any toxin. Even bites that are from a nonvenomous snake or are dry need to be evaluated as they can lead to significant tissue damage or infections.
