Which contaminant issue has frequently appeared higher in farmed salmon than in wild salmon?
Answer
PCBs (polychlorinated biphenyls)
When addressing potential contaminants, PCBs have been a specific point of concern frequently noted to be higher in salmon raised through farming methods compared to those caught in the wild. This discrepancy is often linked to the feed used in aquaculture operations, as opposed to the inherent oceanic conditions of the Atlantic basin itself. Since the majority of globally consumed Atlantic salmon is farmed, this contamination concern tends to be associated with the 'Atlantic' label, though the actual driver is the captive raising method.
