Do Farm Raised Fish Have Higher Levels of Pcbs?

Read Transcript

Fish are what they eat and depending where fish are on the food chain, it's going to be the number one thing you want to look at for mercury and pcbs and that's because as fish eats other fish these toxin accumulate inside in fatty tissues and they frankly do the same thing in your body and my body as well.

So eating fish low on the food chain, whether it's farm raised or wild, is going to minimize your risk of accumulating these mercury and pcbs concerns. The same goes for plants feeding fish, fish that only eat other plants, so Tilapia, Cat fish and actualy [xx] it's a primarily vegetarian diet, even the farm raised have significantly lower risk associated with mercury and Pcb simply because they're not eating on a food chain.

When you get to Salmon, or other big carnivores then yes, that's where the concern can come in and it really boils down to the country. Look at your fish counter for country of origin labeling and just keep in mind that countries have different regulation and qualifications when it comes to what can be in the feed.

In my opinion, farm raised Salmon in the United States or in Norway are sort of the gold standard where you're going to have the lowest risk of mercury and PCB contamination. According to the UN recent report ranking fisheries globally, Norway came in number one with best practices.

So again fish are what they eat, stick low on the food chain, plan eating fish much lower risk whether farmed or wild, and when you're choosing Salmon look at the United States and Norway first.
