The Organization for Economic Cooperation and Development (OECD) Principles of Good Laboratory Practice (GLP) is a quality system concerned with the organizational process and the conditions under which non-clinical health and environmental safety studies are planned, performed, monitored, recorded, archived and reported. Nonclinical health and environmental safety studies covered by the principles of GLP include work conducted in the laboratory, in greenhouses, and in the field. GLP principles are applied to the non-clinical safety testing of test items contained in pharmaceutical products, pesticide products, cosmetic products, veterinary drugs as well as food additives, feed additives and industrial chemicals.
