Frequently Asked Questions: Fish Consumption Advisories
Q: What is a fish consumption advisory?
A: Fish consumption advisories are warnings for people when fish or shellfish are unsafe to eat. The fish may be contaminated with chemicals, like mercury, or they may carry viruses or bacteria from microorganisms. These advisories are issued when humans face potential health threats from eating the fish.
Q: Who publishes fish consumption advisories?
A: The Environmental Protection Agency issues general advisories. States, territories, or tribes may also post safe eating guidelines for the fish in their local waters.
Q: What contaminants can be found in fish and shellfish?
Toxins can also be a natural defense of some animals such as the pufferfish, and plants and fungi. A toxin called histamine may be produced by bacterial action when some fish like tuna, bluefish and mahimahi are not stored soon enough at sufficiently cold temperatures. Cooking and freezing does not destroy biological toxins. Symptoms of paralytic shellfish poisoning (PFP) and ciguatera can occur within minutes and may be lead to severe illness.
Q: Where can I find consumption advisories near me?
A: States and tribes typically have the most up-to-date information about fish consumption advisories. Check with your park to find specific advisories in your area.
Q: Who’s at risk?
A: Eating contaminated fish can make anyone sick. Certain groups like the elderly, pregnant women, nursing mothers, young children, and people who eat a lot of fish could be at higher risk.
Q: Where can I learn more?
A: Learn more about fish consumption advisories on the Environmental Protection Agency website. For specific information about advisories in a park, check with a park ranger, visitor center, or park website.
