This regulation establishes an exemption from the requirement of a tolerance for cerevisane (cell walls of Saccharomyces cerevisiae strain LAS117) in or on all food commodities when used in accordance with label directions and good agricultural practices. Lesaffre Yeast Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of cerevisane (cell walls of Saccharomyces cerevisiae strain LAS117) under FFDCA.
