A warning is out to those who fish at Lake Madison in Madisonville: limit your eating of largemouth bass from that body of water.
The Texas Department of State Health Services has issued an advisory after that species of fish tested from the lake showed elevated levels of mercury.
According to DSHS, adults shouldn't eat more than two, eight-ounce servings each month, and children under the age of 12 shouldn't eat more than two, four-ounce servings per month.
No women who are pregnant, may become pregnant or nursing should eat largemouth bass from the lake.
No other species of fish from Lake Madison are part of the advisory, and the state emphasizes there is not a risk of getting mercury poisoning by swimming, skiing or fishing at the lake.
The brain and nervous system can be harmed with regular consumption of methylmercury, the compound in fish.
Mercury can get into the water by fossil fuels being burned, industrial discharges and emission, and the natural weathering of the earth's crust.
According to DSHS, multiple species of fish were tested, but only the largemouth bass had elevated levels. Officials say there could be a number of factors that would lead to only that species having elevated mercury, including what that fish normally consumes.
