Are octopus safe during pregnancy?

What does the evidence say about octopus during pregnancy?

1. CDC lists raw or undercooked fish and shellfish, including ceviche, among riskier pregnancy foods and advises cooking seafood to 145°F or until the flesh is opaque and separates easily. Fully cooked octopus fits this food-safety principle; raw octopus does not. 1
2. FDA advises 8 to 12 ounces weekly during pregnancy from varied lower-mercury choices on its chart, but the current chart does not list octopus. Squid appears as a Best Choice, but that classification cannot be transferred to a different cephalopod. 2
3. FDA's fish-advice questions and answers explain that a species absent from the chart lacks sufficient reliable mercury information for an assigned category. The absence of octopus therefore creates uncertainty rather than an automatic low-mercury designation. 3
4. A laboratory analysis of fish and seafood consumed in Spain and Portugal measured 0.024 micrograms of mercury per gram in its octopus sample, lower than the tuna and swordfish samples. This was a regional analytical sample, not a pregnancy study or a universal octopus value. 4
5. A separate cephalopod survey found wide cadmium and mercury variation across common, curled, and horned octopus flesh, with some samples above then-applicable European limits. Estimated weekly intakes were below provisional tolerable amounts, but the study did not define a pregnancy serving frequency. 5

Is octopus safe in each trimester?

• First trimester. Avoid raw or undercooked octopus, including carpaccio and ceviche-style preparations. If seafood is hard to tolerate, do not force an octopus serving for nutrition. Choose varied seafood that FDA actually lists as a Best Choice and follow the 8-to-12-ounce weekly total guidance.
• Second trimester. For grilled, braised, or boiled octopus, confirm that the flesh was cooked through and kept separate from raw seafood. Marinating, acid, pickling, smoking, or a surface sear is not the same as reaching CDC's cooking benchmark throughout the food.
• Third trimester. The same cooking and sourcing rules apply through delivery. Seek prompt advice after octopus if fever, repeated vomiting or diarrhea, bloody stool, dehydration, severe abdominal pain, or rapidly worsening illness develops, and tell the clinician when and how it was prepared.
