Abstract

Pollen substitutes are used extensively by German beekeepers and soyabeans are a predominant ingredient in some of these products. Around 40% of global soyabean production is harvested from GM varieties. Thus, pollen substitutes as well as the honey produced by honey bee colonies fed with them might contain GM-soyabean particles. We checked this assumption and found that 23 honeys from 389 samples contained powdered soyabeans. Eleven of the soya-containing honeys and four of 11 pollen substitutes tested in this study contained transgenic material. We did not elucidate the contamination pathway of the honeys, but we consider that these pollen substitutes may well be the source of the GM residues in the honeys.
