Are you going to get it from a northern Minnesota grouse? Get real. Freeze it, brine it, cook it, if you are paranoid, smoke it (I smoke birds and then build a pot of soup with them, it adds a dimension of flavor I really like). I usually bring everything to a quick boil, and turn it off.
Everybody loves it.

If poisoning from birds was going to happen anywhere, it would happen in California. They can’t clean the human feces off the streets in the cities, why would anyone suspect the farms would be run any cleaner?

If wild bird poisoning was a thing, it would be on blast in the liberal media, and there would be legislation to make eating wild birds verboten.

Come on. Find something else to be afraid of.

Best,
