Fish are an important part of a healthy diet. But, if you enjoy eating locally caught fish, it is important to know that fish from local streams and lakes might carry contaminants that cooking does not eliminate, such as mercury and PCBs (polychlorinated biphenyls). The
Environmental Protection Agency recommends checking with your local health department for any advisories and safe-eating guidelines before eating fish caught in your area. This is especially important if you are pregnant or breastfeeding.
