Grocer's itch is a cutaneous condition characterized by a pruritic dermatitis that occurs from coming into contact with mites such as Carpoglyphus passularum (a fruit mite) or Glyciphagus domesticus (a common house mite). Contact usually occurs when handling food with mites in it, such as figs, dates, prunes, grain, cheese, or other dried foods.
