OECD, Decision of the Council C81/30 (final) Annex 2, OECD guidelines for Testing Chemicals, OECD Principles of Good Laboratory Practice, OECD Paris, France, (1981). 

The characterisation of the toxicity associated with a specific chemical is invariably dependent on feeding the chemical to laboratory animals in statistically-based lifetime bioassay, guidelines for which have been agreed at the international level by the OECD (OECD, 1981) and the IPCS (IPCS, 1999), and which are undertaken strictly in compliance with the principles of good laboratory practice (GLP). The animals used in long-term bioassays are... 

Test facilities in the OECD (Organization for Economic Co-operation and Development) member countries that conduct regulatory studies must comply with the OECD Principles of Good Laboratory Practice (GLP), as set out in Council Decision C(97)186/Final. These are referred to as GLP Principles. GLP came into prominence in the late 1970s in response to some malpractice in research and development activities of pharmaceutical companies and contract... 

Note that good laboratory practice (glp) should not be confused with Good Laboratory Practice (GLP). The latter is the name given to a set of principles governing the organizational process and the condition under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, archived and reported, and was put forward initially by the Organization for Economic Co-operation and Development (OECD) (see Chapters 2 and 9). 

D]ata generated in the testing of chemicals in an OECD Member country in accordance with OECD Test Guidelines and OECD Principles of Good Laboratory Practice shall be accepted in other Member countries for purposes of assessment and other uses relating to the protection of man and the environment. 

Member States shall take all measures necessary to ensure that the laboratories referred to in Article 7 of Directive 89/397/EEC1 comply with the general criteria for the operation of testing laboratories laid down in European standard EN 450013 supplemented by Standard Operating Procedures and the random audit of their compliance by quality assurance personnel, in accordance with the OECD principles Nos. 2 and 7 of good laboratory practice as set out in Section II of Annex 2 of the Decision of the Council of the OECD of 12 Mar 1981 concerning the mutual acceptance of data in the assessment of chemicals.4... 

As a tool to make mutual acceptance of risk assessments possible, OECD has developed the concept of Good Laboratory Practice (GLP). The OECD Principles of GLP are an integral part of the 1981 OECD council decision on the Mutual Assessment of Data (MAD) in the Assessment of Chemicals (revised 1997, Section 2.2.2). MAD also harmonizes procedures of GLP compliance monitoring, ensuring that preclinical safety studies are carried out according to the principles of GLP and that countries can have conftdence in the quahty and rigor of safety tests. 

Compliance with the GLP principles covers many aspects of accreditation to ISO 17025. The European Union has adopted the procedures for Good Laboratory Practice of the Organization for the Economic Cooperation and Development (OECD) and calls on member states to take all measures necessary to ensure that laboratories carrying out tests on chemical products comply with the GLP principles. The OECD s GLP principles are part of the Eiuopean Commission Directive 2004/10/EC (http //eur-lex. europa.eu). 

The Aimex I of the Directive 2004/9/EC consists of two parts Part A (Guides for compliance monitoring procedures for good laboratory practice) and Part B (Guidance for the conduct of test facility inspections and study audits). The provisions for the inspection and verification of GLP which are contained in Parts A and B are those contained in Annexes I and II respectively of the OECD Council Decision-Recommendation on comphance with principles of good laboratoiy practice. 

OECD Member States developed the OECD principles of GLP, utilising common managerial and scientific practices and experience from varions national and international sources. The purpose of these principles of good laboratory practice is to promote the development of quality test data. 

Good Laboratory Practice is a quality system that is tailored to the needs of the modem laboratories. Its principles are very close to the principles of the modem quality management systems like ISO 9000 and ISO 17025. However, GLP is specific to the non-clinical health and environmental safety studies, it covers physical and chemical test systems, and gives emphasis to biological test systems. It is of utmost importance to note that GLP principles were set out by the Organization for Economic Cooperation and Development (OECD) and after being modified they were adopted by the Emopean Union and are now the Commission Directive 1999/11/EC.

An important requirement for toxicity tests is their reproducibility and repeatability. In conformation with the principles of good laboratory practice (GLP),27 it is recommended that they be performed according to standard procedures and guidelines prepared by world standardization organizations such as the OECD, ISO, or CEN. Table 9.1 presents a list of selected ISO standards and OECD guidelines with regard to the modality of toxicity tests.

The OECD has produced an internationally accepted set of Principles of Good Laboratory Practice in order to promote the development of quality test data. These have been ratified by the European Commission and transposed into EC Directives. 

The Manager of a testing laboratory is responsible for ensuring that the Principles of Good Laboratory Practice are complied with in the facility. The OECD has set down the minimum responsibilities, which should be to...
