welcome to the board, you don't need 180 degree deyh. The parasites that you refer to is botchilism (sorry for the spelling). And curing salt is used to treat the meat for this. I have done some in the past without the cure, but with fresh meat, marinated in the fridge overnight, and have not have problems. you might want to post this on the camp cooking forum. they talk about this all the time. good luck
