As if the idea of having E. coli wreak havoc on your intestines isn't bad enough, a study conducted by scientists at McGill University in Montreal has found a link between ingesting beef and poultry products and urinary tract infections in women.

It seems there are strains of the E. coli bacteria that can take up residence in your gut, along with that juicy burger, and basically hang out there without causing noticeable symptoms. Brace yourself for what's coming next: When you have sex, the bacteria can travel from the anus to the vagina and lead to a UTI. (Turns out the square footage between the two, err, cavities is shorter in women, which partly explains why we get UTIs more frequently than guys.)

There's more mad news to this beefy tale. In the U.S., 6–8 million women are diagnosed with a UTI each year -- and about 80 percent of the cases are caused by E. coli. An increasing number of women diagnosed with the infection are reporting that their bodies aren't responding to antibiotics commonly used to rid the bug. The possible -- and probable -- reason? All those antibiotics we pump into livestock to keep them healthy and bulky for sale to your supermarket.

We don't know about you, but we're having a veggie dog for dinner.
