Farmed Salmon is Full of Antibiotics and Mercury. Here’s How to Tell If Your Salmon is Safe!

Salmon is not just a delicacy, it’s also one of the healthiest foods you can eat. The fish that belongs to the Salmonidae family is rich in several important nutrients among which there is omega 3.

It’s very tasty when cooked, and can be even consumed raw if it’s high quality wild salmon. Yet, you should be aware that not all salmon is healthy to eat. Its fat content, flavor and nutrients composition depend on where and how the salmon was raised.

Wild salmon vs farmed salmon – How can you tell the difference ?

You can tell a lot about the quality of salmon by the color of its flesh. Farmed salmon tends to exhibit a lighter and pinker color, whereas wild salmon possesses a richer reddish-orange hue. Additionally, farmed fish often show more fatty marbling in their flesh, characterized by wavy white lines, as they do not contend with the upstream currents like their wild counterparts.

Take a look at this example.


Both salmons are Alaskan sockeye, but the one on the right is wild salmon, and the one on the left comes from a fish farm. The color of the wild-caught sockeye is red, while the farmed is pale. This is a clear sign that the fish is not so healthy.

This difference in color is due to astaxanthin – a red molecule present in plankton and algae. Astaxanthin is a powerful antioxidant and has anti-inflammatory properties. It is known to boost the mitochondrial energy production, and improve the circulation of blood. It protects your mitochondria, strengthening their cell membranes. When used as a supplement, astaxanthin can increase your strength endurance by more than half.

Wild salmon, particularly the sockeye, has a high concentration of astaxanthin, as a result of consuming planktons and algae. In the contrast, salmons raised at farms feeds on food pellets, which contain only the synthetic version of asthaxanthin.

The synthetic asthaxanthin is derived from petrochemicals, and is very different from the natural version .
Farmed salmon also consumes fodder that can put you in danger of dioxin and mercury poisoning. As a result of this discovery, some salmon farmers have tried to replace the artificial fodder with corn and soy protein, thus avoiding the contamination.

However, since the fish don’t like eating soy and corn, the quality of this meat is very low. To compensate for that, farmers use antibiotics which keep the fish healthy, but these antibiotics end up in our bodies when we consume them. The vegetable oils found in this food also have negative effect on the omega-3 fatty acids found in salmon meat, and can infect them with mold toxins.

According to FDA and EPA who have both studied the mercury content in fish, the meat of wild salmon does not contain any mercury traces. Having all this in mind you should avoid eating farmed salmon, and stick to the wild-caught.

They’re good source of nutrients, and should be found at your table as often as possible. There are several varieties to choose from at the market. Each has a specific taste, so find which one suits you the best.

Salmon varieties

Sockeye salmon is one of the safest choices at the market, because it’s difficult to farm it as a result of its unique eating habits. Because it primarily feeds on planktons it has a high concentration of good cholesterol, vitamin D and astaxanthin. It also abounds in omega-3 acids and has a strong flavor. It’s especially tasty when smoked.

Chinook salmon (king salmon) has the highest concentration of omega-3 acids, measuring almost three times more than the other varieties. This is a consequence of living in deep, cold waters. Namely, the omega-3 fats keeps them warm, protecting them from freezing. Unlike the previous species, this variety of salmon can be farmed. That is why you should be careful when buying it.

Pacific coho salmon is extremely rich in vitamin D, with good concentration of omega-3 acids.
