The inaugural meeting of the “Pesticides” working group of the then Division of “Food Chemistry and Forensic Chemistry” was held on 22 April 1968 in Frankfurt/Main, chaired by Prof. Dr. Dr. Diemair. At that time, the working group comprised three representatives each from universities, industry and food-testing laboratories, two independent chemists and one employee of the then Federal Health Office. The first tasks of the newly established working group included, among other things, drafting implementing provisions for the national maximum residue limits regulation for plant protection product residues, which had come into force in 1968, and preparing a recommendation on pesticide analysis, including information on the equipment required for a pesticide laboratory, sampling and coordination with other authorities.

In the meantime, the “Pesticides” working group has developed into the largest and oldest working group of the Food Chemistry Society, with around 20 active members and almost 50 corresponding members. Meetings are usually held twice a year. The 100th meeting will therefore take place in Kassel on 11 and 12 November this year. To mark this anniversary, the members of the “Pesticides” working group have decided to hold this meeting as a commemorative session.

Active members, former active members and corresponding members are invited to the commemorative session. The programme will include various ceremonial lectures reflecting the different fields of work of the working group alongside its historical development. An opportunity for an informal exchange of information with all participants is planned for the evening.
