Fishing advisory issued for Lake Como


On Feb. 9, the Texas Department of State Health Services (DSHS) issued a fish consumption advisory for Lake Como in Tarrant County after conducting a laboratory test of fish samples. The testing found elevated levels of dieldrin, dioxins and polychlorinated biphenyls – or PCBs – in common carp.
Although the U.S. Environmental Protection Agency banned the use of these chemicals many decades ago, they break down very slowly in the environment and can accumulate in animals like fish. Long-term consumption of these toxins may cause cancer as well as reproductive, immune system, developmental and liver problems in humans.
As a result, the DSHS advises people to avoid consuming common carp from Lake Como. People can still fish in the area, though they should not consume common carp.
