Increased international travel, worldwide food trade, and consumption of raw and undercooked foods is increasing the exposure of people in the United States to parasitic illness, said researchers in the April issue of Food Technology.
The peer-reviewed Scientific Status Summary, "Parasites and the Food Supply," notes that heightened concern about foodborne parasites also arises from the increasing number of immunocompromised individuals, the emergence of parasites not previously associated with adverse health effects, and the transmission of parasites to food via contaminated water. The summary lists more than 100 known parasites that can be found in the food supply and tells where they originate.
