Mercury in Fish Guidelines

Warning: Mercury in Maine freshwater fish may harm the babies of pregnant and nursing mothers, and young children.

It's hard to believe that fish that looks, smells, and tastes fine may not be safe to eat. But the truth is that fish in Maine lakes, ponds, and rivers have mercury in them. Other states have this problem too. Mercury in the air settles into the waters. It then builds up in fish. For this reason, older fish have higher levels of mercury than younger fish. Fish (like pickerel and bass) that eat other fish have the highest mercury levels.

Safe Eating Guidelines: Mercury

Who	Guidelines
Pregnant and nursing women, women who may get pregnant, and children under age 8	DO NOT EAT any freshwater fish from Maine's inland waters. Except, for brook trout and landlocked salmon, 1 meal per month is safe.
All other adults and children older than 8	CAN EAT 2 freshwater fish meals per month. For brook trout and landlocked salmon, the limit is 1 meal per week.

Small amounts of mercury can harm a brain starting to form or grow. That is why unborn and nursing babies, and young children are most at risk. Too much mercury can affect behavior and learning. Mercury can harm older children and adults, but it takes larger amounts. It may cause numbness in hands and feet or changes in vision. The Safe Eating Guidelines identify limits to protect everyone.

PFAS in Fish Guidelines

Fish tested in several locations found levels of per- and polyfluoroalkyl substances (PFAS) above Maine CDC's recommended levels for regular consumption. Exposure to certain PFAS chemicals has been associated with:

• changes in liver and kidney function,
• changes in cholesterol levels,
• decreased immune response to vaccines in children,
• complications during pregnancy, and
• increased risk of kidney cancer and possibly testicular cancer.

Limit or eliminate consumption of all fish or certain fish species from the waterbodies listed in the table below.

Additional Fish Guidelines: PCBS, DIOXINS, AND DDT

• Fish caught in some Maine waters have high levels of PCBs, Dioxins or DDT in them.
• These chemicals can cause cancer and other health effects.

The Maine Center for Disease Control and Prevention recommends additional fish consumption limits on the waters listed below. Remember to check the mercury guidelines. If the water you are fishing is listed below, check the mercury guideline above and follow the most limiting guidelines.
