Mercury in fish is a concern especially for which groups?

Mercury in fish is mainly methylmercury, a toxin that builds up in fish tissue and can affect the nervous system. The developing brain is particularly sensitive, so exposure during pregnancy and early childhood can interfere with neurodevelopment, potentially impacting IQ, attention, and motor skills. Because methylmercury crosses the placenta and can be passed to a nursing infant, pregnant women and young children are the groups most at risk. The other groups listed do not have this specific vulnerability in the context of developmental neurotoxicity, and shellfish allergies relate to immune responses rather than mercury exposure.
