And some fungal spores can be pretty resistant, too. I keep my mice in the same freezer as our food, but with no physical contact to them. Better save than sorry.
Nope, if there are any bacteria or parasites on the mice, even if they come in direct contact with other frozen food, it won't matter. Having frozen mice in the freezer is just like having any other frozen meat, I would think.
