Rather not recommended
Cod liver may contain heavy metals; it is recommended to avoid it during pregnancy, although occasional consumption does not pose a problem.
Cod liver is a filtering organ that concentrates environmental pollutants: heavy metals (mercury, cadmium), dioxins, and PCBs. These contaminants can cross the placenta and affect fetal development.
Additionally, cod liver is very rich in vitamin A (retinol), which at high doses can be teratogenic (risk of fetal malformations). For the same reason, cod liver oil supplements are not recommended during pregnancy.
If you are looking for a source of omega-3, opt for small oily fish (sardine, mackerel, herring) or a purified fish oil supplement (not cod liver oil).

Cod liver is rather not recommended during pregnancy. It may contain heavy metals and pollutants, and its high vitamin A content can be harmful to the fetus at high doses.
The risks are twofold: contamination by heavy metals (mercury, cadmium) and excess vitamin A (retinol) which can be teratogenic. Occasional consumption does not pose a problem, but it is best to avoid it.
Cod liver oil is not recommended during pregnancy due to its very high vitamin A content. Prefer a fish oil supplement (omega-3) that does not contain excess vitamin A.
