The Louisiana Departments of Health, Environmental Quality, and Wildlife and Fisheries today issue a series of fish consumption advisories for six bodies of water. These most recent advisories include one new warning and updates to five previously issued warnings.

The State issues precautionary advisories when unacceptable levels of mercury are detected in fish or shellfish.

The Department of Environmental Quality conducts fish sampling. LDH then uses this data to determine the need for additional advisories or to modify existing advisories. Each advisory lists the specific fish, makes consumption recommendations and outlines the geographic boundaries of the affected waterways.

** New advisory 

Because of mercury contamination, there are now fish consumption advisories for 49 waterways in Louisiana and one for the Gulf of Mexico.

Louisiana fish consumption advisories are based on the estimate that the average resident eats four meals of fish per month. Consuming more than this from local water bodies may increase health risks.

Mercury is an element that occurs naturally in the environment. Consequently, there are small amounts of mercury in the sediments of streams, lakes, rivers and oceans. Nearly all fish contain trace amounts of mercury. They absorb mercury as they feed on aquatic organisms. Larger predator fish contain more mercury than smaller fish. It is recommended that smaller fish be consumed instead of larger ones.

People are exposed to low levels of mercury throughout their lives. Eating contaminated fish is one way we are exposed to mercury. Health effects from harmful levels of mercury can include nervous system and kidney damage. Young children and developing fetuses are more sensitive to the toxic effects of mercury. Therefore, consumption advisories are issued at lower fish tissue concentrations for women of childbearing age and children under 7 years of age.
