Low Risk

Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

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.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.

José María Paricio, founder of e-lactancia.
