•A SPE-LC-MS/MS method was validated for the analysis of glyphosate and AMPA in oats.•Glyphosate was detected in all the samples and quantified up to 1100 ng/g.•AMPA was only quantified in 9 samples and mass fractions were lower (<40 ng/g).•Oat products were selected for potential candidate refer...
