3 Things to Know About Tuna and Mercury for Pregnant Women

Light tuna is the safest choice Skipjack tuna, sold as canned “light” tuna, has the least mercury. Pregnant women can eat 2–3 servings per week.

Albacore has three times more mercury “White” tuna comes from larger, older albacore. Limit it to one serving per week during pregnancy.

Avoid bigeye and yellowfin tuna entirely These larger species, often used in sushi or steaks, have the highest mercury levels. Skip them completely if you are pregnant or feeding young children.
