Evaluating pesticide residues in Apis mellifera honey from an intensive agricultural region.

). Confirmatory screening identified six pesticide residues banned in the European Union and one banned in Brazil. Pollen analysis suggested that contamination may not be directly associated with bee visits to treated crops. The contamination is likely linked to indirect sources, including non-target plants and environmental exposure, particularly from pesticide drift. These findings highlight risks to honey quality and the need for improved monitoring and regulation.
