Is it safe to eat sushi regularly if you want to lower your PFAS intake?

What's actually in it

Tuna, yellowtail, salmon, and eel are all high-fat marine or farmed fish. Fat is where PFAS accumulate. The chemicals come from firefighting foam runoff, industrial discharge, and general ocean pollution. They bind to fish protein and fat and work their way up the food chain.

Sushi meals are a lot of fish in one sitting. A single roll can have 60 to 100 grams of fish. A regular sushi habit is one of the bigger dietary PFAS sources in US adults who eat this way.

What the research says

A 2026 study in Expo Health measured serum PFAS levels in Asian/Pacific Islanders in the San Francisco Bay Area and correlated them with seafood consumption. Frequent seafood eaters (including sushi regulars) had significantly higher serum PFAS than lower-frequency eaters. The effect was dose-dependent: more meals per week meant more PFAS.

"Once or twice a month" sushi is a very different exposure than "twice a week." Cutting frequency is the simplest change. On the picks side, lower-PFAS options include shrimp nigiri, crab, and tamago (egg). Skipping tuna and eel in favor of sustainable lower-chain fish moves the needle. Vegetable rolls (cucumber, avocado, sweet potato) round out the order without adding to the fish total.
