Determination of Glyphosate Levels in Breast Milk

A study commissioned by the German Federal Institute for Risk Assessment (BfR) in 2015 has confirmed that no residues of the pesticidal active substance glyphosate are detectable in breast milk. For its study, the BfR commissioned two independent and accredited laboratories with extensive experience in the application of the currently most sensitive analytical detection methods for pesticide residues. In order to be able to clarify any possible positive results reliably, two chemical analytical procedures based on different measurement principles were developed and validated for the detection of glyphosate residues in breast milk. The two analytical methods are based on liquid chromatography mass spectrometry (LC-MS/MS) and gas chromatography mass spectrometry (GC-MS/MS).

The results of the study are published in the Journal of Agricultural and Food Chemistry (J. Agri. Food Chem., January 25, 2016, just accepted manuscripts, DOI: 10.1021/acs.jafc.5b05852):
