Three people in Hawaii have come down with what appears to be a rare parasitic disease called rat lungworm disease in recent weeks. Two of the victims (friends who had a meal together) told the Honolulu Star Bulletin that they experienced "agonizing pain" after eating raw vegetables – and physicians fear they may have accidentally swallowed slug larvae hidden inside folds of raw peppers.
