Why is it dangerous to refreeze meat tat was already defrosted?

Hi,

Every time you freeze a slab of meat the bacteria that infest it (every meat has some bacteria on it) do not die. So every time you thaw it back the bacteria continue to grow – thus it become much more dangerous.

It is not that dangerous to freeze more then once if the environment is clean and the meat was fresh to begin with – but supermarket frozen meat is the lowest of the low.

 Just a tip for the freezing problem .What you can do is cook the meat and afterwards freeze it there is no problem in that .

As long as there are still ice crystals in the meat, it is safe to refreeze it, without cooking.  I've done it several times, with no unfavorable results.
