Meat objects created from stone to flesh should rot away (and give food poisoning if eaten before rotting away), the same as corpses, rather than acting as permafood.

Possibly the meat stick should be exempt from this, if it is interpreted to be like a stick of jerky that will not rot easily.

Meatballs, meat rings, meat sticks, and huge chunks of meat all become possibly tainted at the same age as corpses.
