DEQ Fish Advisories

About DEQ Fish Advisories

Although catching and eating fish and shellfish is an important part of the way of life for many Louisianans, there may be health risks associated with eating fish or shellfish harvested from particular water bodies in Louisiana. When harmful chemicals are released into the environment, these chemicals may contaminate some lakes, rivers, streams or ponds. Over time, these contaminants may accumulate in the bodies of the fish or shellfish that live there. When these contaminated fish or shellfish are caught and consumed, the contaminants may get into the body of the person that consumed them, which may pose a threat to human health. Fish consumption advisories are issued when contaminants are found at levels that may potentially impact the public's health.

The Louisiana Department of Health, in conjunction with the Louisiana Department of Environmental Quality (LDEQ), issues fish consumption and swimming advisories to help ensure the safe enjoyment of Louisiana's water resources. The Louisiana Department of Wildlife and Fisheries (LDWF), and the Louisiana Department of Agriculture and Forestry (LDAF) are also consulted during the course of advisory development and dissemination.

The Louisiana Fish Consumption and Swimming Advisory app was designed to protect human health by making fish consumption and swimming advisories readily accessible via an interactive map.
