Mercury in Fish Guidelines

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

  • Pregnant and nursing women, women who may get pregnant, and children under age 8 SHOULD NOT EAT ANY freshwater fish from Maine’s inland waters, except, for brook trout and landlocked salmon, one meal per month is safe.
  • All other adults and children older than 8 CAN EAT two freshwater fish meals per month. For brook trout and landlocked salmon, the limit is one meal per week.

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.
