Not recommended
Swordfish is a fish particularly likely to contain mercury, a compound toxic to the fetus.
It is recommended to avoid swordfish and all large predatory fish (shark, marlin) during pregnancy.
Methylmercury is a neurotoxin that accumulates in large predatory fish at the top of the food chain. It crosses the placenta and can impair the fetal brain development.
Opt for small oily fish (sardine, mackerel, herring) that are rich in omega-3 and very low in mercury. These fish offer the same nutritional benefits without the mercury risks.

Fish to avoid during pregnancy are large predators high in mercury: swordfish, shark, marlin, lamprey. Opt for small fish like sardine, mackerel, or herring.
An occasional serving of swordfish does not pose an immediate danger. The risk is related to repeated mercury exposure. Simply avoid eating it again during your pregnancy.
