This regulation establishes exemptions from the requirement of a tolerance for residues of Gluconobacter cerinus strain BC18B and Hanseniaspora uvarum strain BC18Y in or on all food commodities when used in accordance with label directions and good agricultural practices. Danisco US Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting exemptions from the requirement of a tolerance. This regulation eliminates the need to establish maximum permissible levels for residues of Gluconobacter cerinus strain BC18B and Hanseniaspora uvarum strain BC18Y when used in accordance with this exemption.
