Baltic salmon is relatively low value, because of concern about environmental contaminants, and can be fraudulently substituted for salmon from more premium origins. These very pollutants have been used by a recent study (purchase required) as an analytical marker for geographic origin. The authors used public data from national surveys of dioxins and PCB congeners in salmon to train a Machine Learning classification model. The model could differentiate Baltic salmon from other origins (China, Chile, Canada, Norway, USA, and Vietnam) based on their analytical profile of chlorinated persistent organic pollutants.
