EPA collaborates with states and tribes and develops information to assist them in issuing local fish advisories. To support this effort, EPA conducts and publishes research on fish contamination and fish tissue analyses.
EPA also works with state, tribal and federal partners to provide information about what species of fish are safe to eat, and ultimately works to reduce contaminants in the environment and protect aquatic habitats.
Assisting with Advisories
EPA provides guidance to states, territories and tribes about issuing fish consumption advisories when contaminant levels in fish or water bodies are unsafe. In addition, EPA encourages states to issue safe eating guidelines to inform the public about which fish species are safe to eat without consumption restrictions.
EPA generates fish tissue contaminant data in order to determine safe human consumption rates.
In addition, EPA also provides educational and outreach materials related to fish and shellfish consumption and informs people about advisories where they live.
Studying Levels of Contamination
EPA works internally and with partners to conduct a variety of fish contamination studies. These studies provide data about concentrations of chemicals in fish tissue.
Informing the Public
EPA collaborates with other federal agencies, as well as states and tribes, to inform people about the recommended level of consumption for fish caught in local waters. The goal is to provide up to date information to officials responsible for issuing fish consumption advisories and safe eating guidelines to protect public health.
EPA has worked closely with the Food and Drug Administration to advise at‐risk populations such as women who may become pregnant, pregnant women, nursing mothers, and young children to avoid some types of fish and to eat fish and shellfish that are lower in mercury.
Reducing Contaminants in the Environment
EPA also works to reduce contaminants in the environment to ensure the habitat health of fish populations and other aquatic wildlife. The issues that concern human health are integrally related to ecosystem health. Therefore, EPA is working to reduce contaminants such as pesticides, chemicals and toxics, waste, and excess nutrients – providing benefits for all.
Addressing Shellfish Contamination
Some health departments test shellfish harvested within their jurisdictions to monitor toxin levels and assess the risk for contamination. Depending on the results of such testing, recreational and commercial shellfish harvesting may be prohibited locally during periods of risk.
State and federal regulatory agencies also monitor reported cases of marine toxin poisoning and health departments investigate possible outbreaks and devise control measures.
