Frozen Rats don't have much of a standard compared to most food sold for human consumption, even my wild venison is inspected and deemed safe by the butcher. It isn't uncommon to find feeder rats with parasites, feces or urine on them, and who knows what bacteria, freezing probably kills most or all of it, but there is still a possibility from getting cross comtamination, and then there is the sight of rats in your freezer. I keep mine in small plastic bags wrapped in small paper bags with the freeze-on date, then wrapped up in a big paper bag along with my other frozen pet food in a basket inside my chest freezer with bulk food, opened or small food items are in the kitchen freezer.
None of us are squeamish, and I bought the house, so there is that too. Back when I lived at my folk's house, I kept them in a small freezer, would do the same if anyone had a problem with it, there really is no way to get the majority of people to be OK with keeping rats with food. Can pick a small freezer or fridge/freezer combo for under $200 new, costs around $1 a month to power, and as a side benefit, mom will never look in it, so perfect place to keep your beer![]()
