What Guidelines Say

FDA guidelines recommend limiting tuna intake due to mercury; canned light tuna is safer than albacore or bigeye varieties.

Read more details

FDA and ACOG guidelines categorize tuna based on mercury levels. Canned light tuna is a "Best Choice," allowing 8-12 ounces (2-3 servings) per week. Albacore (white) tuna and yellowfin tuna are "Good Choices," limited to one 4-ounce serving per week. Bigeye tuna is on the "Choices to Avoid" list due to high mercury concentrations. Mercury is a neurotoxin that can cross the placenta and potentially impact fetal brain and nervous system development. Additionally, raw tuna (sushi/sashimi) poses risks of foodborne illnesses like Listeria or parasites. Guidelines emphasize cooking tuna to an internal temperature of 145°F to ensure safety. Monitoring total weekly seafood intake is recommended to stay within safe mercury thresholds while benefiting from omega-3 fatty acids.

Catfish

  • Low-mercury fish
  • Offers protein

Pollock

  • Low in mercury

Canned Light Tuna

  • Classified as a "Best Choice" by the FDA, allowing for 2-3 servings (8-12 ounces) per week.
  • Typically consists of skipjack tuna, which contains lower mercury levels than larger species.

Fully Cooked Tuna Steaks

  • Cooking to an internal temperature of 145°F eliminates risks from parasites and harmful bacteria.
  • Flesh should be opaque and separate easily with a fork.

Canned Pouches

  • Processed similarly to canned tuna and follows the same serving guidelines for light or albacore varieties.
  • Provides a shelf-stable source of omega-3 fatty acids.

Risks & Limits

Bigeye Tuna

  • Contains high mercury levels
  • Listed by the FDA as a "Choice to Avoid" due to consistently high mercury levels.
  • High mercury exposure is linked to developmental delays in the fetal nervous system.

King Mackerel

  • High in mercury

Shark

  • Elevated mercury content

Swordfish

  • High mercury levels

Raw Tuna Preparations

  • Uncooked fish in sushi or sashimi carries a higher risk of parasites and bacterial contamination like Listeria monocytogenes.
  • Pregnant individuals are more susceptible to severe illness from foodborne pathogens.

Excessive Albacore (White) Tuna

  • Guidelines limit white tuna to 6 ounces or one serving per week because of higher mercury content than light tuna.
  • Frequent consumption can lead to mercury accumulation in the bloodstream.
