A Salvadoran fisherman who survived 438 days lost at sea is now being sued by his dead shipmate's family over allegations that he ate the man in order to stay alive.

The family of Ezequiel Crdoba, who was reported to have starved to death months into the ordeal, is seeking $1 million , reports Fox News Latino, citing El Diario de Hoy .

Jose Salvador Alvarenga -- the world's longest surviving castaway -- has repeatedly denied the accusation.
