Remember Bovine spongiform encephalopathy/BSE aka Mad Cow Disease and its human variation variant Creutzfeldt-Jakob disease?
The latter was going to be the death of all meat eaters you'd have thought such was some of the hysteria 15-20 years ago with talk of hundreds of thousands to perish (the
Daily Mail was carrying stories about it only 14 months back) . Typically enough scientists refuse to rule out a long term threat suggesting it could take up to 50 years for vCJD to become apparent in most of those who have eaten infected meat. People have died, about 165 of 175 diagnosed but the diagnosis rate is steady at 2 per year since 2008, I suspect most of us can sleep easily.
What other "OMG we're all gonna die" stories are out there? Avian Flu?, Chernobyl? Mobile phone transmission cancer (that's gone very quite now everyone uses them)?
