Fish on a plate

Put Fish on Your Plate - Follow the Safe-Eating Guidelines to choose fish low in mercury and other contaminants.

Eating fish is good for you - benefits outweigh risks when eating fish low in mercury and other contaminants.

Fish are an important part of a healthy, well-balanced diet. They provide a good source of protein and vitamins such as D and B2 (riboflavin). Fish are rich in calcium and phosphorus and are a great source of minerals, such as iron, zinc, iodine, magnesium, and potassium.

Eating fish is an important source of omega-3 fatty acids. These essential nutrients keep our heart and brain healthy.

Two omega-3 fatty acids found in fish are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Our bodies don't produce these omega-3 fatty acids so we must get them through the food we eat. Omega-3 fatty acids are found in every kind of fish, but are especially high in fatty fish. Some good choices are salmon, trout, sardines, herring, canned mackerel, canned light tuna, and oysters.

Omega-3 Fatty Acids:

Help maintain a healthy heart by lowering blood pressure and reducing the risk of sudden death, heart attack, abnormal heart rhythms, and strokes.
Aid healthy brain function and fetal development of vision and nerves during pregnancy.
May decrease the risk of depression, ADHD, Alzheimer’s disease, dementia, and diabetes.
May prevent inflammation and reduce the risk of arthritis.

Health experts recommend that fish be included as part of a healthy diet:

If you plan to eat the fish you catch at waterbodies with low PFAS, also check the Safe Eating Guidelines below for information about how many servings of those fish to safely eat for you and others you share your catch with.

Safe-eating guidelines

Fish from all sources can contain contaminants. You should consider store-bought and locally-caught fish when making choices about eating fish. Minnesota Safe-Eating Guidelines for eating fish depend on the fish you eat and who you are. If you are pregnant, planning to be pregnant or have children, you and your children need to be more careful about the kinds of fish you eat and how often you eat fish.

By following these guidelines, you can lower your exposure to contaminants in fish, and still get the benefits of eating fish.

First check Waterbody Specific Safe-Eating Guidelines to see if there are more restrictive guidelines for fish species you catch in MN lakes and rivers.
Next check Statewide Safe-Eating Guidelines for general guidelines for fish from Minnesota waters or the store/restaurant.

Waterbody Specific Safe-Eating Guidelines provide advice for lakes and rivers where fish have been tested and contaminant levels in some fish species are higher. Follow the MDH Statewide Safe-Eating Guidelines, except for species listed in the Waterbody Specific Safe-Eating Guidelines.

Some lakes and rivers in the East Metro Area of the Twin Cities have advice to not eat fish due to high levels of PFOS in fish and/or water.

Statewide Safe-Eating Guidelines are based on mercury and PCB levels measured in fish throughout Minnesota and on levels of mercury found in commercial fish. They also take into account findings of low levels of Perfluorooctane Sulfonate (PFOS) in fish throughout Minnesota. Not all waters in Minnesota have been tested for contaminants in fish.

When choosing which fish to eat, some people need to be more careful than others. It's important you make your fish choices based on who you are.

Young children (under 15 years old) and fetuses are more sensitive to mercury. Too much mercury can cause lasting problems with understanding and learning. However, studies show children benefit developmentally when moms eat fish low in mercury during pregnancy.

How clean a lake looks is not a sign of how safe the fish are to eat

Mercury is found in most fish – both locally-caught and store-bought.

How much mercury is in fish depends on:
- Species. Some fish have more mercury than others because of what they eat and how long they live – Bass, Northern, and Walleye have higher levels than panfish.
- Size. Smaller fish generally have less mercury than larger, older fish of the same species. Unlike people, fish do not get rid of mercury.
Fish from lakes in northeastern Minnesota generally have more mercury than in southern and central Minnesota.
Fish bought at a store or restaurant also contain mercury. Farm-raised fish, such as salmon, are low in mercury but can contain other contaminants that may be found in fish feed. The amount of contaminants is small enough that farm-raised salmon are still good to eat 2 times a week.

Perfluorooctane Sulfonate (PFOS) is found at low levels in fish throughout the state. Higher levels have been found in fish from some waters in the metro and Duluth areas. See also PFAS in fish from Minnesota Pollution Control Agency.

Polychlorinated biphenyls (PCBs) are highest in fatty fish such as Carp, Catfish, and Lake Trout from major rivers and Lake Superior.

See Contaminants and Minnesota Fish for more information.

A typical fish meal is made up of 1 serving of fish. MDH's Safe-Eating Guidelines give advice for the number of servings of fish to eat per week or month.

Body Weight	Weight in ounces of uncooked fish	Approximate weight after cooking
50	3	2.25
70	4	3
90	5	3.75
110	6	4.5
130	7	5.25
150	8	6
170	9	6.75
190	10	7.5
210	11	8.25

One piece of sushi is about one ounce.
A fast food fish sandwich is typically between four and five ounces of cooked fish.
A serving of fish is based on the body weight of the person eating the fish. For example, ½ pound (or 8 ounces) of uncooked fish is one serving for a 150-pound person. Eight ounces of uncooked fish is equal to about 6 ounces of cooked fish.
To adjust meal serving size for a heavier or lighter weight person, add or subtract 1 ounce of fish for every 20 pounds of body weight.
