Why do vultures eat scavengers without getting sick?

In the first analysis of the bacteria residing on and in the vulture, the researchers found that the scavenger bird was full of the decomposing Fusobacterium bacteria and the toxic Clostridia bacteria. When these bacteria decompose a dead body, they secrete toxic chemicals that make corpses a dangerous food for most animals.

Meanwhile, vultures often wait until the rotting process takes shape, making them more accessible to dead animals with tough skin. Moreover, they also often begin to eat rotten flesh from the anal part to enjoy the full heart. The dish of vultures is therefore filled with toxic feces and bacteria, but they seem to be immune to these deadly dangerous germs.
