The consequences of the use of pesticides in agricultural activities for food and feed product safety are subjects of major concern. In the present work, simple and environmentally friendly methodologies were applied to the analysis of soil and cattle feed samples collected in dairy cattle farms from Galicia (NW Spain). This forms part of an integrated study aiming to investigate the global impact of the use of pesticides in such farms. The target compounds were 36 plant protection products belonging to different families. Organochlorine and organophosphorus pesticides were the most commonly detected compounds in the analyzed samples; pyrethroid and chloroacetanilide pesticides were also found in some of them, but not so frequently. Detected levels were rarely above the established legal limits.
