The Texas Department of State Health Services says people should avoid eating any fish and blue crab caught in the Houston Ship Channel, the San Jacinto River below the Lake Houston Dam and north of Highway 146. Authorities say the seafood there tested positive for elevated levels of dioxins, pesticides and polychlorinated biphenyls or PCBs and regularly consuming it may increase the likelihood of long-term health risks.
Authorities also say spotted sea trout and blue crab from the Upper Galveston Bay should be avoided because it poses the same health concerns.
An advisory for all species of catfish remains in effect for all of the Galveston Bay System.
Women of childbearing age and children under 12 are being asked to avoid eating seafood from those areas entirely, according to the state health department. Other adults are encouraged to limit their consumption to no more than one meal per month.
However, authorities say it is now safe to consume spotted sea trout from a portion of Galveston and Trinity Bays and all of East and West Bays. The area is south of a line from Red Bluff Point to Five-Mile Cut Marker to Houston Point.
