**FOR FURTHER INFORMATION CONTACT:**

Chelsea Cerrito, Center for Veterinary Medicine, Division of Animal Food Ingredients, Food and Drug Administration, 12225 Wilkins Ave., Rockville, MD 20852, 240-402-6729, *[email protected].*

**SUPPLEMENTARY INFORMATION:**

FDA is amending the food additive regulation at 21 CFR 573.450 *Fermented ammoniated condensed whey* for use in animal feed to update the production organism *Lactobacillus bulgaricus* that has been scientifically reclassified to *Lactobacillus delbrueckii.* This action is being taken to improve the accuracy and clarity of the regulations.

Publication of this document constitutes final action under the Administrative Procedure Act (5 U.S.C. 553). FDA has determined that notice and public comment are unnecessary because this amendment to the regulations provides only technical changes to update scientific nomenclature and is nonsubstantive.

Therefore, under the Federal Food, Drug, and Cosmetic Act, and the Public Health Service Act, and under the authority delegated to the Commissioner of Food and Drugs, 21 CFR part 573 is amended as follows:

**Authority:**

**21 CFR Part 573**

2. In § 573.450, in paragraph (a), remove “ *Lactobacillus bulgaricus* ” and in its place add “ *Lactobacillus delbrueckii* ”.
