Why don’t vultures get food poisoning from eating rotten meat?

The acid in vulture’s stomach is almost 10 times as concentrated as ours. This destroys bacteria so efficiently that vulture droppings are actually more hygienic than the meat they eat! But a strong stomach isn’t  enough by itself, because once bacteria have multiplied in a decaying carcass, they release chemical toxins that aren’t destroyed by acid. To counter this, vultures absorb the toxins directly through the lining of their throat and then neutralize them using antibodies present in the blood.
