Rotten Flesh

Rotten Flesh is an item from the 1.8 update dropped from zombies in place of feathers; eating it restores some of your hunger meter. However, there is a large risk that after eating it your hunger meter will deplete at a faster rate (an example of food poisoning). As of the pre-release testing, poisoning causes no damage by itself, but does sometimes cause the player to be unable to eat. It is unclear whether poisoning causes creatures to do increased damage to the player or not. As of the 1.8 Pre-release, the poison effect causes a player to take half as much damage (it is unclear if this is a bug or an intended effect). As of the official 1.8 release, rotten flesh will always cause the player to get food poisoning when used to restore the hunger meter to full. Food poisoning depletes the hunger bar by 2.5 points over a period of time. The poison effect is similar, if not the same, as other raw foods such as raw chicken. Rotten flesh cannot be cooked or used in any crafting recipes.

Rotten flesh heals Wolves without poisoning or causing damage to them. This will be useful in that players can optionally feed them an item that has no other use at the moment so that they may save their cooked pork for themselves.

Trivia
The food poisoning effect does not stack, so using rotten flesh from no food points can get you up to 7.5 food points.
