Is It Harmful to Eat Too Much Salmon?

Eating too much salmon can be harmful. Eating too much salmon can lead to many different health risks. These risks include:


Salmon has been found to contain a persistent organic pollutant known as polychlorinated biphenyls (PCBs). Persistent organic pollutants tend to be linked to both obesity and type 2 diabetes. PCB levels are found to be 5 to 10 times higher in farmed salmon compared to wild salmon, so keep this in mind when deciding which type of salmon to eat.


If you eat too much salmon or too much of any type of fish, it is likely that you could be exposed to carcinogens or cancer-causing chemicals. Fish tend to come into contact with these chemicals when they are swimming in polluted waters. This risk can be found in both wild salmon and farm salmon.

Nervous System Damage

Salmon, as well as all other fish, contain certain levels of mercury. A high level of mercury is often not an issue for most adults. A high level can be harmful to the nervous systems of fetuses as well as small children, which is why pregnant women are often told not to eat fish.

How Many Times Can You Eat Salmon?
