Salmon is one of the most popular fish in the world Its characteristic pink-orange hue makes it instantly recognizable on the plate or at the market. However, did you know that some salmon sold today is artificially dyed to achieve that desirable color? While food authorities consider dyed salmon safe for consumption, many consumers want to avoid fish that has been altered cosmetically So how can you determine if the salmon you are buying has been dyed? In this comprehensive guide, we will go over the telltale signs of dyed salmon and provide tips for sourcing naturally colored salmon.
Why Salmon Farmers Dye Their Fish
Fish farms dye salmon and other fish to give them a more visually appealing coloration. Wild salmon develop their vibrant reddish-orange pigment from eating krill, shrimp, and other small crustaceans containing natural astaxanthin and carotenoids. Farmed salmon raised in pens lack access to these pigment sources in their diet. To compensate, some salmon farms add synthetic astaxanthin or canthaxanthin dyes directly to the fish feed. This artificially colors the salmon’s flesh. While controversial, this practice is approved and considered safe by food authorities. However, many environmentally-conscious consumers want to avoid dyed fish.
6 Ways to Identify Dyed Salmon
Here are the top indicators that the salmon you are buying may have been treated with artificial dyes:
1. Unnaturally Uniform Color
Dyed salmon often has an overly consistent, bright hue compared to the natural variations seen in wild fish. When examining the flesh, it may appear artificially “perfect”
2. Lighter Pinkish or Orange Tone
Wild salmon naturally develop a deeper red-orange shade. Farm-raised salmon can look distinctly paler pink without the addition of dye.
3. Lack of Fine Fat Lines
Wild salmon have thin white lines of fat marbling their flesh. This comes from their active lifestyle foraging in the ocean. Farmed salmon have a higher overall fat content and lack these fine fat lines.
4. Explicit Labeling
In some regions, labeling laws require the disclosure of any added colorants. Check for phrases like “color added” or specific dye names in the ingredients.
5. Sold Out of Season
Wild salmon availability follows natural seasons, with peaks in summer and fall. Fresh “wild” salmon sold in winter is likely farmed and potentially dyed.
6. Lower Price Point
Inexpensive salmon fillets almost always come from aquaculture farms where dyeing is more likely. Higher-quality wild salmon comes with a higher price tag.
Ask Questions to Determine if Your Salmon is Dyed
If you are still unsure if a salmon has been treated with dye, ask the seller directly about their sourcing, diet, and production practices. Here are some key questions to ask:
-
Is this salmon wild-caught or farm-raised? Wild is less likely to be dyed.
-
Where is the salmon from? Some regions use more dye than others.
-
Has any color been added to the feed or flesh? A transparent seller will disclose this.
-
Do you use synthetic or natural astaxanthin in the diet? The latter colors salmon naturally.
-
Is the salmon certified organic or sustainable? These producers avoid dyes.
Health and Environmental Impacts of Dyed Salmon
Government agencies consider approved salmon color additives safe for human consumption. However, some consumers still prefer to avoid dyed salmon, especially pregnant women and parents of young children. There are no major health risks, but traces of petroleum-based dyes used in some farms can accumulate in fatty tissues over time. The aquaculture industry is moving toward plant-based natural pigments like algae-derived astaxanthin to reduce potential health and environmental impacts.
Finding Naturally Colored Salmon
To avoid salmon that has been artificially colored, purchase wild Pacific or Alaskan salmon in season when available. Look for reputable eco-certification labels like Organic, Best Aquaculture Practices (BAP), or Ocean Wise on farmed salmon. If buying farmed salmon out of season, ask for local product that has not been dyed. Building a relationship with a transparent fishmonger or grocer is the best way to ensure you are getting salmon in its true, natural shade of pink-orange.
How to Distinguish Farmed vs. Wild Salmon
FAQ
How to know if salmon is colored?
The first indicator of fresh salmon is its colour: it should always be a lovely, bright pinkish-orange hue. While colours can vary slightly according to salmon species, the key is the brightness of the meat. If your salmon looks dull, pale or discolored, it is not fresh at all and could be spoiled.
Is supermarket salmon dyed?
There is no before or after, because there is no part of the farming process that calls for salmon to be dyed.Dec 21, 2022
Does wild caught salmon have dye in it?
Wild salmon take in astaxanthin from eating algae, krill, and other small crustaceans; while farmed salmon have this vitamin mixed in with their food. Asataxathin is a dietary supplement in salmon feed to obtain the desired pink to red-orange color in the fish’s flesh.
How can you tell if salmon is cooked by color?
How Can I Tell When It’s Done? Salmon will change from translucent (red or raw) to opaque (pink) as it cooks. After 6-8 minutes of cooking, check for doneness, by taking a sharp knife to peek into the thickest part. If the meat is beginning to flake, but still has a little translucency in the middle, it is done.
