Glyphosate is a crop protection active ingredient for the control of weeds, which is approved in the EU until 2022. According to the World Health Organization’s Cancer Agency, glyphosate is “probably carcinogenic” to humans. However, the BfR assesses glyphosate as non-carcinogenic when used correctly.
Glyphosate in beer
During a review, low levels of glyphosate residue were found in several beers. It is supposed that the active ingredient gets into the beer through the grain malt or hops used. Although glyphosate is used in the cultivation of hops, the hop cones are not treated. It is therefore more likely that the active ingredient enters the beer through the grain malt. Glyphosate has been used in cereal cultivation since the 1970s and malt is made from barley or wheat.
Lower detection limits for glyphosate
bilacon is now accredited to detect glyphosate with lower detection limits, so that even very small traces of glyphosate in beer can be detected.
Thus, we are able to detect in the trace range with
- a limit of determination of 0,02 µg/L
- and a detection limit of 0.01 µg/L
For glyphosate residues in beer there are no legal maximum residue levels regulated in the EU 396/2005 regulation. However, the processing factors collected by the BfR allow an evaluation of the residues via the maximum residue levels for malting barley.
