My current boi has Kuru (laughs like a maniac once every 2 mins or less) but I haven't eaten human steak.

I was very close to someone who did eat human steak, and I even picked up some human steak and carried it away from the house I was taking refuge in, but definitely didn't eat any.

Can you get Kuru from just holding human steak, or is this a bug? And is there any way to cure this, cuz it's super annoying being judged as a cannibal in-game whilst I'm actually not one...
