Wild salmon is 3x as expensive as farmed, but it does have higher, healthful omega-3 fatty acid levels. PCBs are stored in fish fat, and wild salmon doesn’t consume contaminated feed. It swims unpenned, fattens naturally, and feeds on algae, not fish oil and ground up fish. A recent Science Magazine analysis showed salmon farmed in Scotland had the highest
PCB contaminants. Salmon farmed near Chile and Washington state had levels as low as wild salmon. So this choice seems easy. And delicious–buy a full pound here or a full 4 pounds of Wild King Salmon from Alaska here.
