pesticide residues in honey
Parameters: Among others the following pesticides can be queried (at least 5): tau-fluvalinate, DEET (N,N-diethyl-m-toluamide), deltamethrin, glyphosate, piperonyl butoxide, bifenthrin, boscalid, lambda-cyhalothrin, malathion, chlorpyrifos, acetamiprid, thiamethoxam. Additional pesticides that can be queried can be found on the DRRR home page on the list of analytes published by DRRR: https://drrr.de/ringversuche/lebensmittel-und-futtermittel/
Article Number: 2011004
Description: Bees pollenize about 80% of agricultural crops, which are treated with different pesticides. Consistently, pesticide residues are found in honey. The honey however may only be sold if certain prescriptive limits are not exceeded. The proficiency test design includes at least 2 samples in different concentration ranges: this allows participants to demonstrate their ability to ensure the accuracy of results even in different concentration ranges and, at the same time, fulfills an important part of the requirements for method validation according to SANTE 11312/2021.
Category: chemical-physical testing food and feed honey and beeswax
