The Seafood Nutrition Guide (Fish & Shellfish)
Atlantic salmon, farmed
FDA/EPA Best choice (listed as “Salmon”) in the FDA/EPA Advice about Eating Fish (revised October 2021). How much and how often is their advice, not ours.
Low mercury & PCBsOn the Dietary Guidelines’ even-lower-mercury list, and its dioxin + PCB figure is at or under 0.62 pg TEQ/g — the level at which 8 oz a week stays within EFSA’s weekly limit for a 70 kg adult. A threshold we publish, not a safety rating. How
Composition per 100 g as eaten — cooked, or canned and drained. Mercury is FDA’s species mean, as FDA publishes it; for species FDA does not cover, the sample-weighted mean of the surveys listed. Dioxins + PCBs are survey means (or a median, where noted) per gram of fish as sold, in each survey’s own TEQ scheme. Composition comes from Norway's 2026 food table, not USDA. USDA's farmed Atlantic salmon row carries about twice the EPA + DHA; Norwegian monitoring of 1,108 farmed salmon found median EPA + DHA fell by more than 60% from 2005 to 2020 as feed moved toward plant ingredients (Moxness Reksten et al., Food Chemistry 2022). The USDA row stays as a second reading.
