According to a new U.S. Geological Survey study, scientists detected mercury contamination in every fish sampled in nearly 300 streams across the United States.
More than a quarter of these fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental Protection Agency. More than two-thirds of the fish exceeded the U.S. EPA level of concern for fish-eating mammals.
Exposure to mercury can damage your brain, kidney and lungs. Symptoms of mercury poisoning typically include sensory impairment, disturbed sensation and a lack of coordination.
