Minecraft wiki entry for Things_not_to_do, associated text: Be careful when eating rotten flesh and raw chicken as each may inflict the Hunger status effect on the player, making actions drain the hunger bar much faster. A piece of rotten flesh has an 80% chance of inflicting food poisoning for 30 seconds, and a piece of raw chicken has a 30% chance. (However, if in dire need, eating raw chicken, or even rotten flesh, is a viable option if the player takes no action while under the Hunger effect.) Eating a spider eye always poisons the player, causing 4 damage. Avoid eating these unless there is no better food available. Pufferfish are extremely dangerous and should not be eaten at all (unless trying to obtain A Balanced Diet or How Did We Get Here? advancement), as it causes Hunger III for 15 seconds, Nausea I for 15 seconds (makes the player's view wobble), and Poison II. This makes eating pufferfish not an option almost whatsoever due to the damage from the Poison and the massive increase in hunger bar drainage. However, it is possible to nullify both by drinking milk.
