Background
The use of validated methods is one of the basic criteria
for testing compliance with Codex Standards. The Joint FAO/IAEA Expert Consultation
on Validation of Analytical Methods for Food Control recommended that in
certain cases the validation of a procedure could be done in one laboratory
operating under internationally recognised quality system such as GLP, ISO/IEC
Guide 25, or by Peer Review. However, the full in-house validation of a
multi residue method (MRM) covering a wide range of matrices is practically
impossible according to the current validation guidelines. The IUPAC Interdivisional
Working Party on Harmonisation of Quality Assurance Schemes for Analytical
Laboratories is preparing a draft guidance document on In-house method validation,
and a "Practical approach to validation of multi-residue methods"
is being elaborated by an international group of practising analysts with
the co-ordination of the FAO/IAEA Training and Reference Centre for Food
and Pesticide Control.
Objectives
To bring together analytical chemists and representatives
of agencies, governments, standard organisations and accreditation bodies
involved in method validation in general, and specifically for residue analysis
of pesticides, veterinary drugs and mycotoxins to:
