Two studies observed very little difference in mercury levels between wild and farmed salmon (11, 22). Yes, I would like to receive emails from The Norwegian American. For this reason, the omega-3 to omega 6 ratio is about three times higher in farmed salmon than wild. On the other hand, Chile — the world’s second largest producer of farmed salmon — has been experiencing problems due to excessive antibiotic use (29). We feature content that is relevant to Norwegian Americans as part of our mission to connect them with their heritage and build bridges with contemporary Norway. Thank you – tusen takk! Healthline Media does not provide medical advice, diagnosis, or treatment. This article explores the potential risks of antibiotics in foods. These changes may reflect lower levels of PCBs and other contaminants in fish feed (21). We’ll go over the toxicity of mercury and who benefits most from doing a mercury detox. The table below provides a good comparison. Here are 11 nutrition facts and health benefits of salmon. It is important to keep in mind that farmed salmon is still very healthy. Due to the high density of fish in aquaculture, farmed fish is generally more susceptible to infections and disease than wild fish. While farmed salmon has three times the total fat of wild salmon, a large part of these fats are omega-6 fatty acids (1, 8). However, salmon is generally not farmed in these countries (25). For comparison, Norway used an estimated 1 gram of antibiotics per ton of harvested salmon in 2008 (29, 30). Still, one study showed that the levels of common contaminants, such as PCBs, in Norwegian, farmed salmon decreased significantly from 1999 to 2011. Unregulated and irresponsible use of antibiotics is a problem in the aquaculture industry, especially in developing countries. All rights reserved. (You can unsubscribe anytime). Here’s what you need to know about mercury poisoning, including the basics about mercury poisoning from eating fish. However, not all salmon is created equal. Just three ounces of salmon, she says, contains 17 grams—nearly your entire meal’s quota. Antibiotic use in fish farming is an environmental hazard as well as a potential health concern. Traces of antibiotics may cause allergic reactions in susceptible individuals (25). However, one study determined that wild salmon had levels three times higher (23). In any case, trace metals in either variety of salmon occur in such low amounts that they’re unlikely to be a cause for concern. The annual global production of farmed salmon has increased from 27,000 to more than 1 million metric tons in the past two decades (2). Though farmed salmon is much higher in omega-6 fatty acids than wild salmon, the total is still too low to cause concern. Many scientists speculate that this can drive increased inflammation and may play a role in modern pandemics of chronic diseases, such as heart disease (7).

Fish is high in omega-3 fatty acids, and can help protect against many diseases. The negative connotation is that some people regard salmon farms as environmentally harmful. Wild-caught salmon usually have less saturated fat compared to farmed salmon. Conversely, wild salmon is higher in minerals, including potassium, zinc and iron. Farmed salmon may contain higher amounts of contaminants than wild salmon. If you’re concerned about antibiotic resistance, it might be a good idea to avoid Chilean salmon for now. It is not the species itself that is bad, it is a fine fish to eat. Researchers suggested that if the EPA guidelines were applied to farmed salmon, people would be encouraged to restrict salmon consumption to no more than once per month. Antibiotics are commonly used in food-producing animals worldwide. Our website services, content, and products are for informational purposes only. Farmed salmon is higher in vitamin C, saturated fat, polyunsaturated fatty acids and calories. Antibiotics in farmed salmon are also problematic, as they may increase the risk of antibiotic resistance in your gut. In a four-week study in 19 people, eating farmed Atlantic salmon twice per week increased blood levels of the omega-3 DHA by 50% (10). Get news and highlights from America's only Norwegian newspaper delivered right to your inbox each Friday. Arguably the most dangerous pollutant found in salmon is PCB, which is strongly associated with cancer and various other health problems (15, 16, 17, 18). What is a healthy portion size? But half of the salmon sold worldwide comes from fish farms, which use a process known as aquaculture to breed fish for human consumption (1).
