Tapeworms top a global list of food-borne pathogens

Three types of tapeworms found in pork and fresh produce take the three leading places in a list of the 10 "food-borne parasites of greatest global concern" issued by the Food and Agriculture Organization and the World Health Organization. "The parasites affect the health of millions of people every year, infecting muscle tissues and organs, causing epilepsy, anaphylactic shock, amoebic dysentery and other problems," says FAO.
