Texas Mercury Advisories and Bans

The Seafood Safety Division of Texas Department of Health is charged with issuing advisories and bans when a threat to human health may occur from consumption of contaminated fish. Texas has no routine monitoring of mercury in fish, and more advisories may be needed in order to protect health, especially for children and pregnant women. The threshold level for determining mercury advisories, .7 ppm in Texas also should be tightened in order to protect health.

Fish advisories are online at

  • The entire Gulf Coast of Mexico - king mackerel
