Strange meat

 is a food item found in Fallout 3. Strange Meat is actually human flesh. It can restore some of your Hit Points, but also gives you a small amount of radiation. You can only buy or loot it from hunters, who are often seen "hunting" lone wastelanders. Old Man Harris in Andale will reveal that Andale's residents are cannibals and strange meat is found in their residences. The shed in Andale has Wastelander corpses on a bench, obviously being butchered, and the nearby refrigerators contain Strange Meat, making the connection obvious.
