The Seafood Nutrition Guide (Fish & Shellfish)
Shrimp
FDA/EPA Best choice (listed as “Shrimp”) 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. No wild or farmed tag: NOAA Fisheries finds 93% of shrimp eaten in the US in 2023 was imported and almost 96% of imports with a recorded method were farmed, but US wild-caught shrimp is sold too, and the USDA row does not say which it measured.
