Investigating Foodborne Cryptosporidium and Giardia in Clams Harvested Near Iqaluit, Nunavut
High prevalences of Cryptosporidium and Giardia were reported in enteric illness patients in Nunavut, Canada, with a foodborne, waterborne, or animal source of parasites suspected. Clams (Mya truncata) are a commonly consumed, culturally important, and nutritious country food in Iqaluit, Nunavut; ho...
