The Seafood Nutrition Guide (Fish & Shellfish)
Bigeye tuna, wild
FDA/EPA Choice to avoid (listed as “Tuna, bigeye”) 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. USDA SR Legacy has no bigeye tuna row, so composition cells stay empty. Tagged wild: this species is caught, not farmed, for the US market, and NOAA Fisheries describes the US catch as wild-caught.
Mercury(ppm)
High mercury — an FDA/EPA Choice to avoid.
FDA — Mercury Levels in Commercial Fish and Shellfish (1990–2012): Tuna (fresh/frozen, bigeye), mean of 21 samples (FDA 1993–2005) (2005)
Dioxins + PCBs(pg TEQ/g)

An empty cell means we do not yet have a method-cited source. Rank 1 wins the published rule; it is not medical advice.
