Sorry but that's is incorrect info and a false sense of security. The parasites inside a living mammal will survive just fine when the outside temps drop.
Many toxins will be unaffected by freezing and there are diseases and parasites that can also survive for considerable periods of time below zero (usually in the egg stage ).

But, since you don't want our advice, I'll just ignore the fact you are intentionally playing russian roulette with your snakes health and assume you also eat crap from the dumpster as your main diet.
Feed your snake a meal from a clean, healthy supply. Everone else has had these ideas before and there is a very compelling set of reasons you don't find the hobby as a whole running around with moustraps.![]()
