Mandy, thanks for that. We moved from the UK a few years ago, and one reason for the discontent was the food police and the whole What If? Syndrome. The same nonsense is coming here, but there's still a huge sense of the pioneer, doing things for yourself. Yes, I could have someone else kill and butcher my pigs, but equally I could simply go buy some pork and have done with it!
It does mean, however, that we have to relearn some things that we have delegated to the 'experts' and lost a feel for. Hence, the question... we 'know' that ideal storage temperature is 2-4c, but I suspect that in reality there is a margin above that which is still perfectly safe. Commercial production has to reduce risk to the nth degree, and so we have the 4c max recommendation.
Maybe this is the wrong forum for such a question, I'll see what the deer hunters have to say...
