What is mercury and should I be concerned when eating fish?
Mercury occurs naturally in the environment and accumulates in the aquatic food chain, including in fish, as methyl-mercury. This means all fish contain some methyl-mercury. The good news is that most fish in Australian waters have very low mercury levels.
It is important to note that mercury from fish is generally not a health consideration for most people, it is only an issue for women planning pregnancy, pregnant women, breastfeeding women and children under six.
