we got advice from DHS (post fires) that even if the meat and stuff appeared to be in good quality, it wasn't a good idea to refreeze and eat it later, especially for those with sensitive stomachs etc

in your circs, i'd be defrosting everything properly, and doing a hell of a lot of cooking in the next couple of days. nothing that has been defrosted at all gets refrozen (and i ONLY defrost in the fridge) - it gets cooked somehow and then refrozen already cooked into a meal
