Another mad cow

Mad cow # 6 was announced today. This one came from Wakamatsu via Hokkaido.
To put this in persepctive, Britain’s mad cow epidemic was 155,000 cases over a ten year span–as many as 1,000 new diagnoses per week at its peak. So Japan’s six cases in a year isn’t as bad, but it’s still not good.
I’ve been eating beef. Have I also been playing prion roulette?
