Kuru is only an issue when a human that has a particularly high amount of prions is eaten, or when someone eats an area of a human with high amounts of prions (i.e. The brain).
Basically, kuru is only transferred in a minority of cases. Other users have posted only one well known instance of mass transmission of the disease even though that tribe is not the only tribe to practice funerary cannibalism.
My favorite novels are nonfiction or realistic fiction, so if that's not your jam, ignore me. On the Road or The Dharma Bums by Kerouac, To Kill a Mockingbird by Lee, The Glass Castle by Walls, Walden by Thoreau.
