Mercury in Fish

Mercury Levels
Although fish is a nutritious food - it is low in fat and is a good source of protein and other nutrients - some fish contain levels of mercury that are unhealthy for human consumption.

At Risk Fish
The Department of Health has advised women of childbearing age and children under 6 to avoid certain types of fish that have high amounts of mercury including:
  • Fresh-caught or frozen tuna
  • King Mackerel
  • Shark
  • Swordfish
  • Tilefish
Women & Children
Women of childbearing age should not eat more than 1 can of tuna fish per week (or 6 ounces). A woman or child who weighs under 135 pounds should eat less than 1 can of tuna per week. Children under 6 should eat less than half of a can of tuna (3 ounces) per week.
