The Utah Department of Health added two new locations and one new fish species to its Mercury Fish Consumption Advisory list on Wednesday, warning residents about elevated levels of mercury for those who may catch or consume fish in the following locations:

Newcastle Reservoir in Iron County — no one should eat wiper caught or harvested there.

Red Fleet Reservoir in Uintah County — children and pregnant women should not eat largemouth bass, and adults should limit their consumption to two 8-ounce servings per month.

Steinaker Reservoir in Uintah County — children and pregnant women should not eat bluegill, and adults should limit their consumption to two 8-ounce servings per month.

An 8-ounce serving is the size of two decks of playing cards. According to an analysis completed by the Utah Department of Health, eating more than these amounts over a long period of time could result in an intake of mercury that exceeds the U.S. Environmental Protection Agency's health recommendations.

Fish have tested for mercury in 268 bodies of water in Utah since 2000, including 194 streams and rivers and 74 lakes and reservoirs, and fish in 16 of the 268 waterways had elevated levels of mercury. Past advisories for elevated mercury levels include the following:

Sept. 30, 2008 — for brown trout from Porcupine Reservoir in Cache County; brown trout from Rock Creek below Upper Stillwater Reservoir in Duchesne County; brown trout from East Fork Sevier River between Otter Creek and Piute Reservoirs in Piute County; for largemouth bass from Sand Hollow Reservoir in Washington County.
