These fish are considered unclean and have the potential to contain toxic mercury that readers should consider avoiding.

Unlike river salmon, ocean salmon is classified by the US Food and Drug Administration (FDA) as the type of fish most susceptible to mercury contamination because they live at the bottom of the sea where 80% of the mercury in the water above has been destroyed by sunlight.

When consuming fish with high mercury levels like ocean salmon, toxic substances will gradually accumulate in the human body. Long-term consumption can lead to mercury poisoning, damage to the oral, dental, and digestive systems, as well as serious kidney problems.
