The Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology (CCQM) is celebrating World Metrology Day on 20 May 2023, and is happy to present a series of short recordings covering the importance of metrological traceability and equivalence of measurements in food safety, trade and authenticity. Topics include measurements, reference materials and interlaboratory comparisons related to: allergen detection, emerging contaminants, GMO detection, alternative proteins, food packaging, mycotoxins and pesticides. The activities support the global food system and compliance with high quality standards to protect the health of consumers and foster the global food trade.
