Proficiency testing “Food and feed”

With our proficiency testing programme for food and feed, we offer you a comprehensive selection of various matrices (dairy products, animal and plant foods, beverages, feed and much more). Over 200 proficiency tests from the following disciplines

chemical-physical testing

e.g. for ingredients and additives, residues and contaminants, pesticides, allergens

molecularbiological-immunological testing

e.g. determination of animal species and genetically modified organisms (GMOs)

organoleptic (sensory) testing

e.g. triangle test, ranking test, simple descriptive test, profile test

are available to choose from.


For the year 2024/25, we have included the following new proficiency tests in the programme, among others:

Per- and polyfluorinated alkyl substances (PFAS) in various foods.

The concentration ranges are always adapted to the respective matrix (ng/kg, µg/kg, mg/kg), the following PFAS are tested:

- CAS 1763-23-1 (perfluorooctane sulfonic acid)

- CAS 335-67-1 (perfluorooctanoic acid)

- CAS 375-95-1 (perfluorononanoic acid)

- CAS 355-46-4 (perfluorohexanesulfonic acid)

Pesticides in various foods

Our new proficiency testing programme "Pesticides" was developed with leading experts in the field of pesticide analysis. The sample design takes into account the measurement of blank samples and covers different concentration ranges. All relevant matrix groups according to SANTE 11312/2021 are covered.


For technical reasons, you can currently find our proficiency tests for environment in the Food and Feed catalog:

- CO2 evolution test (ISO 9439, OECD 301B)

- Zahn-Wellens, EMPA test (ISO 9888, OECD 302B)

- Plastic materials - aerobic biodegradability (ISO 14855-2, ASTM D5338-15)

- Plastic materials - aerobic biodegradability (ASTM D5511)
