OK, so we shouldn't refreeze meat once it's been defrosted.
But if I've partially defrosted meat, then popped it back in the freezer, is that safe? Specifically I'm thinking of sausages or steaks or chops, which may be frozen in groups. You might want to pull them out of the freezer for 30 mins to 1 hr, so they thaw just enough to loosen up to separate them, then put half back. Is this safe?
My question is ... is there a clean cut off point with defrosting after which it becomes unsafe to refreeze, or does it just get progressively more dangerous?
