The Seafood Nutrition Guide (Fish & Shellfish)
Swordfish, wild
FDA/EPA Choice to avoid (listed as “Swordfish”) in the FDA/EPA Advice about Eating Fish (revised October 2021). How much and how often is their advice, not ours.
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. Tagged wild: this species is caught, not farmed, for the US market, and NOAA Fisheries describes the US catch as wild-caught.

Dioxins + PCBs(pg TEQ/g)
Not tested
Not tested — no survey we cite covers this species. Lifestyle lists score it at the 75th percentile of tested rows (1.27 pg TEQ/g): untested is not treated as clean.
