Rotten food

Rotten food is food that has been attacked by ghasts in Mort Myre Swamp. It is inedible and nearly useless, although it can be converted into stew by receiving an Abidor Crank event during Temple Trekking. This is a friendly event where all that happens is Abidor Crank appears and heals/blesses the player and turns all rotten food in the player's inventory into stews automatically.

Food becoming Rotten food in the swamp can be prevented by carrying (or wielding) either a Silver sickle (b), a Rod of Ivandis, an Ivandis flail, Druid pouch, or an Ouroboros pouch.

It is also found during the Zogre Flesh Eaters quest when looking through the backpack.
