Women who are pregnant, nursing, or plan to become pregnant: The DSHS Seafood and Aquatic Life Group (SALG) staff collected Should not consume any of the species affected from the Neches fish samples from the Neches River in June and September 2007. River Mercury was also found in high levels in 2004/2005 by the TCEQ and TPWD in earlier studies, which prompted the DSHS survey in Fish from the lower section of the Neches River (Composite Site 1) 2007. The Texas Parks and Wildlife Dept.
