I don't mean does it need to be served frozen but as a safety precaution should all meat spend a certain amount of time in the freezer to kill bacteria or parasites before being thawed to feed? I'm asking because I'm out of any red meat and am going to the market tomorrow. I was supposed to meet up with a friend a few days ago to get some frozen venison from her but couldn't. If I get beef hearts and pork tomorrow it won't have been frozen and so far I've made sure everything my guys have eaten has spent at least a few days in the freezer before feeding it to them. Can I give them heart without a trip through the freezer or does it matter?
