And they just found another case of BSE in a cow in the USA. But really, everything is fine. Don't worry.
They are randomly testing only something like one out of every 12,000 bovines, the last I was able to confirm. And yet they keep turning up every couple of years.
It will be very interesting to see how old this dairy cow was. If it was born in the US after 1997, when it became illegal to grind up one cow and feed it to another cow, then that's going to be very bad news for the US beef industry. It would mean that the 1997 rules aren't working.
I think the only way to be sure that US beef is safe is to test more. When you only test 1 in 12,000 animals, you don't know jack.
