Read this excerpt from "Mad Cow, Furious Farmer” and consider the resource provided at the end of the passage.

Eventually, in 1997, governments began to ban farmers from feeding their livestock high-risk meat and bone mixtures. With that ban, the epidemic quickly peaked, and by 2010 had largely disappeared. Over the years, half a million cows and two hundred people had been killed by prions.

In the end, the BSE epidemic was a watershed moment, or turning point, in public health. Citizens were enraged at their governments for having kept prions a secret. Governments, who had lost the public trust, struggled to find the best way to communicate health risks without creating unnecessary panic.
