If you are looking for wild salmon, check your local grocery store or specialty grocery store in your neighborhood. You can also find wild salmon in the wild. Just kidding, but true. Like wild salmon, farmed salmon is low in mercury. However, a few years ago, studies found that farmed-raised salmon contained more contaminants (particularly in Europe) than wild salmon; this led people to look for wild salmon as a source of Omega-3 fatty acids. There’s no straight answer to whether farm-raised or wild salmon has more omega-3 fat—it depends on what they eat. You will pay a premium for wild salmon versus farm-raised. If money is tight, the health benefits of eating two or three weekly servings of farmed-raised salmon (a serving being four to six ounces) outweigh potential risks
