Environmental pollutant that is used for manufacturation of batteries, fungicidal products, dental amalgam, and contaminated fish.

Most of mercury present in breast milk does it as an inorganic substance which is almost non-absorbable. Breastfeeding should be discontinued whenever a mother is contaminated or intoxicated. It may be a source of neurological troubles.

Benefits of breastfeeding are largely more important than risk related to the presence of mild level environment pollutants in human milk, in many instances, they are at lower content than those found in cow’s milk or other foods. (Codex alimentarius FAO-WHO).


We do not have alternatives for Mercury.
