Titanium dioxide, potential carcinogenic for humans, detected in milk

“Massively used in a multitude of everyday products” (toothpaste, solar creams, drugs, plastics, makeup, paper, paints, etc.). Therefore, used as a white and opacifying color in food (E171), titanium dioxide was however prohibited in food as a precaution in France in 2020 and then in the European Union in 2022, recall researchers.

“In 100 % of animal milks” – Titanium dioxide, potential carcinogenic humans,

“We already knew that there were some in ecosystems. in water, seas, lakes, rivers, worldwide, thanks to many recent studies,” said Anne Burtey, research manager at INRAE, who supervised the project. However. different forms of titanium dioxide particles have been found in “the maternal milks of ten volunteer women living in Paris or in the near suburbs, at variable rates, certain women with up to 15 times more particles than others”, which proves that this substance “can pass the barrier of the mammary gland”, titanium dioxide, potential carcinogenic humans, reports the study. It was also present in “100 % of animal milks (fresh. powder, from cows, donkeys or goats)”, both from organic and conventional farming, and 83 % of infant milks (from trade, 1^is au 3^e age, organic or not) analyzed by researchers.

The effects of this impregnation on human health are not known, for lack of studies on the subject. “This inventory of the current contamination of milks reflects the level of exposure of newborns. mothers, but also adult milk consumers,” say researchers.

Titanium dioxide has been classified as a potential carcinogenic in humans by inhalation since 2006. recall the scientists of INRAE (National Research Institute for Agriculture, Food and the Environment), the AP-HP (Public Assistance-Hospitals of Paris), Synchrotron Soleil and CNRS, the National Center for Scientific Research.
