Fish From Three Iowa Lakes Exceed Mercury Advisory Level
DES MOINES - The Iowa Department of Natural Resources has confirmed the presence of mercury above consumption advisory levels in tissue samples from largemouth bass collected from Red Haw Lake in Lucas County, Upper Centerville Reservoir in Appanoose County, and Grade Lake in Clarke County.
Individuals should consume no more than one meal per week of largemouth bass caught from these three lakes.
Every year Iowa DNR biologists collect samples of fish for laboratory analysis to determine the wholesomeness of fish for human consumption. Edible portions of these fish are analyzed by a certified lab and results are compared to consumption advisory levels as identified by the DNR and Iowa Department of Public Health in the state's consumption advisory protocol. The risk-based protocol went into effect in 2006 and is based on US EPA and FDA guidance. This protocol is the basis for issuing consumption advisories for Iowa waters.
This brings the total number of advisories in Iowa to 14. All of Iowa's consumption advisories recommend that individuals should consume no more than one meal per week of the fish species of concern.
Previous advisories issued for Iowa lakes include Cedar Lake in Cedar Rapids for common carp and channel catfish, and Cedar Bend Lake for common carp in Linn County for PCBs. Advisories due to mercury have previously been issued for largemouth bass at Lake Geode in Henry County, Morman Trail Lake in Adair County, Nine Eagles Lake in Decatur County, and North Banner and South Banner lakes near Indianola,.
Other advisories in Iowa rivers have previously been issued for mercury include the Cedar River from Floyd County north to the Minnesota border for smallmouth bass, walleye and northern pike; the Upper Iowa River from the lower dam in eastern Winneshiek County upstream 24 miles for any species of fish; and the Volga River, including the Little Volga and the North Branch Volga River from the town of Volga upstream in Clayton County for smallmouth bass.
Mississippi River Pool 12, which is the area between Lock and Dam 11 in Dubuque and Lock and Dam 12 at Bellevue in Jackson County, has a consumption advisory for walleye, sauger, largemouth bass, smallmouth bass, white bass and northern pike.
The DNR has information on these contaminants and consumption advisories on its Fish and Fishing webpage at www.iowadnr.gov/fish/index.html then click on Fish Consumption Advisories in the navigation bar on the left.
Fish are still part of a healthy diet. To achieve the most health benefits - which also include proper growth and brain development in children - the Iowa Department of Public Health recommends that Iowans of all ages should eat fish at least twice per week. This includes fish you buy or catch yourself.
