Abstract
We tested the presence of glyphosate in the urines of a farmer who sprayed a glyphosate based herbicide on his land, and in his family, as his children were born with birth defects that could be due to or promoted by pesticides. Glyphosate residues were measured in urines a day before, during, and two days after spraying, by liquid chromatography-linear ion trap mass spectrometry. Glyphosate reached a peak of 9.5 µg/L in the farmer after spraying, and 2 µg/L were found in him and in one of his children living at a distance from the field, two days after the pulverization. Oral or dermal absorptions could explain the differential pesticide excretions, even in family members at a distance from the fields. A more detailed following of agricultural practices and family exposures should be advocated together with information and recommendations.
Highlights
We previously reported two cases of birth defects in a farmer’s family including imperforate anus, growth hormone deficiencies, hypospadias, heart defect and micropenis [1]

Summary
We previously reported two cases of birth defects in a farmer’s family including imperforate anus, growth hormone deficiencies, hypospadias, heart defect and micropenis [1]. This pattern has rarely been described and overlapped the Stratton-Parker syndrome whose aetiology remains to be discussed [2]. GBH are the major pesticides used by this farmer and can be relevant biomarkers of pesticide exposure. GBH is a major herbicide used on this farm but all over the world. This was performed before, during and after spraying following usual agricultural practices. We tested if the farmer wife and three children at a distance from the field were contaminated
