What is mercury and methyl mercury?

Mercury is a chemical element that occurs naturally in the environment in the air, water and soil. When mercury accumulates in the water it is turned into methyl mercury which fish absorb as they feed in the waters. Over time the mercury levels build up in the fish, some more than others depending on what they eat, and when we catch and eat these fish we consume this mercury too.

What types of fish have the highest levels of mercury? 

Most fish and shellfish contain some mercury but larger fish at the top of the food chain that have been living for a long time generally have higher levels because they’ve had more time to accumulate the mercury. Fish including swordfish, barramundi, orange roughy, shark and king mackerel seem to pose the greatest risk to pregnant women.

How can mercury harm my baby?

Although research is ongoing it appears that consuming high levels of methyl mercury during pregnancy can harm your baby’s brain and nervous system. The effects may not be apparent for years after your child is born but can seriously affect your child’s cognitive skills, language, motor skills and vision.

Why shouldn’t I just give up eating fish altogether?

If you choose to eat fish with low levels of mercury during pregnancy then the risks of harming your baby are very slim and you’ll also be reaping the benefits from eating fish. The fatty acids found in fish are vital for your unborn baby’s brain and eye development so don’t give up on it entirely.

What fish are safe to eat during pregnancy?

Some types of fish that are low in mercury as well as high in healthy fats are mackerel, rainbow trout, salmon and sardines. Shellfish with low levels of mercury include prawns, lobster and oysters. It is recommended that pregnant women eat no more than three serves of fish per week (in the low level of mercury category) and if they do choose to eat fish in the high mercury level category then it should be restricted to one serve per fortnight.
