Biphenyl and Anthraquinone in Organic Herbs, Spices and Tea

At its last meeting, the German BNN has decided to release a public state­ment on the application of the BNN orientation value for biphenyl and anthraquinone detected in organic herbs, spices, herbal teas and tea.

Background

Biphenyl is not only detected in fresh (potted) herbs, but also in dried organic herbs and spices and in organic tea. In addition, Anthraquinone has been detected for some time in the same product groups. Biphenyl and Anthraquinone are mainly due to combustion processes and their detection alone does not imply a breach of the Council Regulation on Organic Agriculture. However, since Anthraquinone and Biphenyl are applied as pesticides, they are subject to pesticide legislation according to EC 396/2005. For this reason, a public statement of the BNN was essential as a guideline on how to deal with findings in organic products.

Summary

Findings up to 0.05 mg/kg Biphenyl and 0.02 mg/kg Anthraquinone are to be considered as random or inevitable according to this public statement. For organic products, the BNN statement is taken into account when findings are assessed on your GALAB Certificate of Analysis.
