The Seafood Nutrition Guide (Fish & Shellfish)
Squid, wild
FDA/EPA Best choice (listed as “Squid”) 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 squid only raw or fried, so there is no as-eaten composition row and those cells stay empty. Tagged wild: all squid production is wild capture.
Mercury(ppm)
FDA — Mercury Levels in Commercial Fish and Shellfish (1990–2012): Squid, mean of 36 samples (FDA 2005–2009) (2009)
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.
An empty cell means we do not yet have a method-cited source. Rank 1 wins the published rule; it is not medical advice.
