I know you’re joking, but humans eating humans is how you get kuru disease. The only safe way to eat a person is to process them into Soylent Green first.
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.
Kuru is just one form of prion disease that was found in one group of people. And from what I remember, it has never been found elsewhere, as it most likely developed as a sub-type of Creutzfeldt-Jakob disease(another prion disease)
