How do vultures avoid food poisoning?

Vultures eat animals that may have died naturally weeks ago. This putrid flesh is often so riddled bacteria that it would be lethal to any other animal. Vultures protect themselves against this in two ways. First their stomach acid is almost ten times as concentrated as ours. This kills bacteria and viruses so effectively that vulture droppings are more hygienic than the food that they eat.

The toxins that have already been produced by the time the vulture feeds are absorbed into the lining of its throat and neutralised by antibodies in the blood.
