re: Cottonmouth bites MS boy on the face

Snake venom varies in consistency from region to region, even within the same species. Then you have different species of venomous snakes that have different types of venom.

Finding certain snake species is very difficult, as local populations become fragmented, or disappear altogether.

The antivenom production process is tedious and painstakingly slow. It has to be purified and tested on animals before it can be packaged, freeze dried and ready for shipment.
