I stopped eating beef after our family had some bloody prime rib for a Christmas dinner some 16 years ago. I still continue to eat other meats. I don't know if this news would stop me from ordering McDonald's fries though, which I consider to be the best fries of any fast food establishment. And how do we know that other places, like Burger King or Wendy's, doesn't do the same thing? This article from Malcolm Gladwell is also interesting.[via astrogirl, Metafilter]
