I live in the USA but I am often very worried about mad cow disease. It's the main reason I stopped eating beef (I never ate it that often anyway). Every now and then I will be at a friend's house for dinner and beef is the only option so I figure, what the heck. But then inevitably I freak out that I could have gotten mad cow. But then I remember that there's never been a confirmed human case from eating US beef.
Is this a totally crazy thing to worry about? I'm at the point where I don't want my family to eat beef either.
