Although professionals working on dairy cattle farms come into contact with a wide range of chemicals and microbiological agents, little is known about this possible exposure, which occurs a priori via inhalation and skin contact.

The aim of this research is to gain a better understanding of this chemical and microbiological exposure, and this research focuses in particular on professional women working on dairy cattle farms , who may be in charge of specific activities not commonly carried out by professional men.

Exposure to pesticides, antiparasitic products and disinfectants will be the first substances to be investigated, followed by other chemical or particulate compounds present in everyday and professional environments. Exposure to these compounds will be measured by their presence in the urine, feces (if possible) and hair of around 60 participating women, as well as in bovine tuft/head hair and, if possible, air samples taken in milking buildings.

• Adult woman working on a dairy cattle farm in the "Grand Ouest" region of France
• Woman who speaks and understands French
