Recent international data have shown that the levels of chemical substances found in human milk could be at risk for breastfed infants. New data are necessary to assess this risk among French newborns.
The objective of this study is to assess levels of certain contaminants in breastmilk. Measurements will be made on breastmilk samples collected in Milk Bank but not suitable for infants due to bacteriological reasons. 6 Milk Banks well distributed on the French territory will be contacted to participate. 180 women will be included. Women who gave their milk and correspond to the inclusion criteria (in particular breastfeeding a child under 6 months at the time of the donation) will be contacted by the investigator by phone. They will be asked to fill in a written consent as well as a questionnaire on socio-demographic data, pregnancy related information and potential environmental exposures. 2 breastmilk samples of 50 mL will be sendsending to the lab for analysis and 2 samples of 50 mL will be collected.
