Title: AOAC INTERNATIONAL


1
Performance Requirements for New and Modern
Methods an EU perspective
  • AOAC INTERNATIONAL
  • June 25-26, 2009, Rockville, MDWolf Maier,
    Counselor, Food Safety, Health, Consumer Affairs

General Rule for Analytical Methods
  • Regulation (EC) No 882/2004 of the European
    Parliament and of the Council of 29 April 2004 on
    official controls performed to ensure the
    verification of compliance with feed and food
    law, animal health and animal welfare rules
  • Article 11 Sampling and analysis methods used in
    the context of official controls shall comply
    with relevant Community rules or
  • If none exist, internationally recognized rules
    or protocols, for example those that the European
    Committee for standardisation (CEN) has accepted
    or those agreed in national legislation

3
General Rule for Analytical Methods
  • If no internationally recognized protocols exist,
    other methods may be used that are suitable for
    the intended purpose and developed in accordance
    with general scientific principles
  • Validation may take place within a single
    laboratory according to an internationally
    accepted protocol

4
Community Reference Laboratories
  • Community reference laboratories (Article 32)
  • Provide national reference laboratories with
    methods
  • Organize comparative testing in accordance with
    internationally accepted protocols, when
    available
  • Make technical advances in the field
  • Training of staff from national reference
    laboratories and of experts from developing
    countries
  • Dispute settlement where Member States contest
    the results of analyses
  • Collaborate with laboratories in third countries

Characterization
  • Wherever possible, methods of analysis shall be
    characterized by the following appropriate
    criteria
  • Accuracy, precision, repeatability
  • Applicability (matrix and concentration range)
  • Limit of detection, limit of determination
  • Recovery, selectivity
  • Linearity, measurement uncertainty
  • Precision values (from collaborative trial
    conducted in accordance with e.g. ISO 5725 1994
    or IUPAC International Harmonised Protocol)

6
Performance Criteria
  • Where performance criteria for analytical methods
    are established, they must be based on criteria
    compliance tests
  • Repeatability and reproducibility values must be
    expressed in an internationally recognized form
    (e.g. 95 confidence intervals)
  • Methods of analysis which are applicable
    uniformly to various groups of commodities should
    be given preference over methods which apply only
    to individual commodities

7
Standardization
  • The Commission may lay down
  • Methods of sampling and analysis, including the
    confirmatory or reference methods to be used in
    the event of a dispute
  • The performance criteria, analysis parameters,
    measurement uncertainty and procedures for the
    validation of such methods
  • Rules on the interpretation of the results

8
Standardization
  • Standardized methods of analysis are of
    importance to guarantee safety and ensure the
    free circulation of feed and food within the EU
  • However, DG SANCO intends to establish methods of
    analysis only in very specific cases as regards
    safety of feed and food
  • Standardization of methods is largely entrusted
    to CEN

9
Putting These Principles Into Practice
  • COMMISSION REGULATION (EC) No 152/2009 laying
    down the methods of sampling and analysis for the
    official control of feed
  • Replaces 19 pieces of specific legislation
  • Deleted 50 of the analytical methods from the EU
    books (next year 50 of the rest)
  • Prescriptive only for empirical methods where
    result depends from protocol (starch, sugar)
  • Performance criteria for all other methods

Other Examples for Performance-Based Requirements
for Analytical Methods
  • Mycotoxins in food (Regulation 401/206)
  • Nitrates in certain foods (Reg 1882/2006)
  • Dioxins in certain foods (Reg 1883/2006)
  • Lead, cadmium, mercury, inorganic tin, 3-MCPD and
    benzo(a)pyrene in food (333/2007)
  • Analytical methods for veterinary drugs, hormones
    and growth promotors in animals and animal
    products (Decision 2002/657)
