MAD COW IN MILK?

"Cause of mad cow disease may be found in milk," blares this Globe and Mail article from Canada, and although that's a little stripped-down as a summary of a complex study, it gets to the point, especially for vegetarians who aren't vegan. Whether or not there's 'as much suffering in a glass of milk as in a pound of steak,' there just may be a soupcon of Mad Cow in there as well. Worth it?
