How are animals, specifically carrion birds, able to eat rotting flesh without ill effect?

In: Biology

In a number of ways.

One is that they can have stomach acid a lot stronger than that of non carrion eaters. This can kill a lot of bacteria.

Their immune systems have also evolved to deal with the bacteria and their toxins and so they have a large number of antibodies always ready to go to neutralise them.

And just like us they have bacteria in their intestines but they’ve evolved to use the ones that would be deadly to us to help them digest their food.

Humans are carrion eaters. Carnivores prefer their meat during or immediately after the kill.

Is there a point where something is too rotten for vultures to eat?

Two vultures are taking a vacation and try to board the airplane carrying a couple of dead rabbits.

“Would you like me to check those for you?” the gate agent offers.

“No thanks,” they reply. “They’re carrion.”

It so happens that if all of your ancestors ate rotting flesh, you too would be able to eat rotting flesh.
