Guidance Document Estimation of LOQ for Measurements in the Field of Contaminants in Feed and Food
5 months agoIn this Guidance Document on the Estimation of LOQ for Measurements in the Field of Contaminants in Feed and Food of 2022 the four EURLs working in the field of contaminants - EURL for metals and nitrogenous compounds (MN), EURL for mycotoxins and plant toxins (MP), EURL for processing contaminants (PC) and EURL for halogenated POPs in feed and food (POPs - aim to describe, in a joint document, one recommended and generally applicable approach for estimation of LOQ. Other approaches may then be used only for sound reasons, e.g. if required by EU legislation or in case of elevated background levels.
The concept presented in this new guidance document consists of the following major routes:
- the general approach based on the lowest validated level
- alternative approaches for sound reasons
- and the consideration of the contribution of procedural blanks
Specific approaches for the different covered contaminants (metals & nitrogenous compounds, mycotoxins and plant toxins, processing contaminants and halogenated POPs) are additionally included.
