Yep, that is definitely the case, unfortunately, and has been for quite some time. The UK had a bad time of it with mad cow disease and scrapie (the version that impacts sheep) getting into the food supply from affected animals for a number of years, but they did finally manage to get it under control by outlawing the use of certain types of feed and introducing other safety controls at farms. The US is actually set to start importing beef and lamb from the UK next year for the first time since 1996.
Creutzfeldt-Jakob disease is transmitable via transfusion, so the Red Cross has to take steps to protect the blood supply, but there's no known way to test for it in donor blood, so they can't do it after the fact, and the only way to definitively diagnose it in humans is via brain biopsy (which sometimes misses the effected areas) or at autopsy. That means a ban on blood donations by people at elevated risk for having contracted the disease, and since Creutzfeldt-Jakob has been known to sit around inactive for 50 years before triggering, that means the ban will be with us for a long time. And it's not just the UK - because UK beef and lamb was widely exported to most of Europe between 1980 and 1996, anyone who spent more than 3 months cumulatively during that period in a fairly long list of countries is banned from giving blood in the US and other parts of the world.
