I think it's been at least 10 years or more since the crisis. I haven't heard anything either. I get the impression that they've got a handle on the situation. Apparently, the U.S. immigration people aren't taking any chances though. When I arrived home from a trip to the UK, I heard an announcement asking that anyone who had contact with livestock there to tell I forgot who. I trampled around the countryside quite a bit and in areas that had cow pats (although I did my best to avoid them). So, in my conversation with whoever the offical person was, I found out that they were only concerned if I was going to have contact with any livestock in the U.S. I live in an urban area though.
So, I guess the danger is over, the food supply is safe and they just want to keep it that way.
Oh, and I did eat beef while over there, on both trips, back just after the scare was over and this last time. I'm fine. :)
