Looks like Canada is think about allowing markets to sell ground beef that has been treated with radiation. This would supposedly help kill off E. Coli bacteria.

I don't think I would be too pumped about eat beef that has been treated with radiation. I don't know how much research has gone into it, but I just see 10 years from now health problems being linked to it though.
