If you don’t eat the brain you’ll have a much much lower risk (your link suggests about 9x less likely), and if the person you eat wasn’t a cannibal then your risk is lower still.

Also worth mentioning that Kuru is a specific disease for natives in Papua new guinea , and it only existed for about 100years and was going away on it’s own when the cannibalistic practice was outlawed.

I think the health risks of cannibalism is very exaggerated.

(this is not an endorsement of cannibalism)
