People are exposed to mercury (Hg) through the consumption of fish. State and federal governments provide broad, often- generalized food safety guidance to reduce exposure; however, numerous rural fishing areas lack testing and location- or species- specific guidance. The aim of this study was to provide tangible, visible, or easily measured characteristics of Lake Trout Salvelinus namaycush that could convey information on Hg exposure to people harvesting and consuming fish where no location- specific guidance exists.
