Fish and shellfish can be a source of high quality protein in your diet. Fish and shellfish, however, can accumulate contaminants from the waters in which they live. The Texas Department of State Health Services (TDSHS) monitors fish in the state for the presence of environmental contaminants and alerts the public through bans (closures) and advisories when a threat to human health may occur from the consumption of contaminated fish.

Typically, fish and shellfish do not contain levels of contaminants high enough to cause an imminent threat to health even after a few meals. Health risks from contaminants may increase for people who regularly consume larger fish and predatory fish from one area of contaminated water over a long period of time. To reduce health risks in areas of contamination, people should consume fish from a variety of waterbodies and should generally eat smaller fish. Following TDSHS guidelines and recommendations will significantly decrease health risks and allow a maximum level of protection for persons consuming fish from areas of known contamination.

Consumption bans and advisories are updated by the TDSHS as needed. In waters with consumption bans, possession and consumption of fish and/or shellfish is prohibited. Catch and release fishing from these areas is allowed. A consumption advisory is a recommendation to limit consumption to specified quantities, species, and sizes of fish. For more information, visit the TDSHS website or call the TDSHS at (800) 685-0361 (shellfish) or (512) 834-6757 (fish).
