2 Overview Historical perspective: FDA s involvement in plant breeding and plant biotechnology FDA s regulatory approach: Legal authority related to food from GE plants How to consult with us: The types of data and information FDA evaluates Past consultations 2

3 Regulating plant breeding: A historical perspective 1938: The Federal Food Drug & Cosmetic Act 1958: Food Additive Amendment Food additives require approval Exempted: Substances whose uses are Generally Recognized as Safe (GRAS) 1970: Regulation on plant breeding and GRAS Emerging concerns cited: Glycoalkaloids in potatoes Endogenous defensive compounds Key vitamins and nutrients 3

4 Regulating plant breeding: A historical perspective 4

5 Regulating plant breeding: A historical perspective 1986 Coordinated Framework USDA EPA FDA Existing legal authorities sufficient Endogenous Substances Must not contain substances at levels that are harmful Including sufficient levels of key nutrients (1970) Added Substances Ingredients must meet safety criteria, may require FDA review and approval Including substances added through biotechnology (1984) 5

6 Regulating plant breeding: A historical perspective FDA s 1992 Statement of Policy: Foods Derived from New Plant Varieties FDA views on plant breeding in general Discussed new methods of biotechnology Endogenous Substances Must not contain substances at levels that are harmful Added Substances Ingredients must meet safety criteria, may require FDA review and approval Labeling Labeling must be truthful and not misleading (misbranding) Recommended consultation Flow charts to help developers determine if important safety and regulatory concerns exist 6

10 What does GRAS mean? GRAS: generally recognized, among experts qualified by scientific training and experience to evaluate its safety, as having been adequately shown through scientific procedures (or, in the case of a substance used in food prior to January 1, 1958, through either scientific procedures or experience based on common use in food) to be safe under the conditions of its intended use. (FD&C Act, Section 201(s)) 10

11 What does safe mean? With respect to added substances: Safe or safety means that there is a reasonable certainty in the minds of competent scientists that the substance is not harmful under the intended conditions of use. (Code of Federal Regulations 170.3(i)) 11
