Michael Taylor, deputy commissioner for foods and veterinary medicine, will leave the F.D.A. on June 1.

WASHINGTON — The Food and Drug Administration on March 8 announced Michael Taylor, deputy commissioner for foods and veterinary medicine, will leave the agency on June 1, 2016. Stephen Ostroff, who led the F.D.A. as acting commissioner until the recent confirmation of Robert Califf as commissioner, will succeed Mr. Taylor as deputy commissioner for foods and veterinary medicine.

Mr. Taylor joined the F.D.A. in July 2009 and was named to his current position in 2010. Mr. Taylor has led the implementation of the F.D.A. Food Safety Modernization Act and guided nutrition-related initiatives to reduce the risk factors for chronic disease and other adverse diet-related outcomes. He has overseen the move to eliminate the use of certain antibiotics that may contribute to the development of antimicrobial-resistant bacteria.

A nationally recognized food safety expert, Mr. Taylor has served in numerous high-level positions at the F.D.A., as a research professor in the academic community, and on several National Academy of Sciences expert committees studying food-related issues. He also served as administrator of the U.S. Department of Agriculture’s Food Safety and Inspection Service (F.S.I.S.) and acting undersecretary for food safety at the U.S.D.A.

Mr. Taylor said he plans to continue working in the food safety arena, focusing on those settings where people lack regular access to sufficient, nutritious and safe food.

Stephen Ostroff will succeed Mr. Taylor as deputy commissioner for foods and veterinary medicine.

Prior to serving as acting F.D.A. commissioner, Dr. Ostroff was named the agency’s chief scientist in 2014 and was responsible for leading and coordinating the F.D.A.’s cross-cutting scientific and public health efforts. Dr. Ostroff joined the F.D.A. in 2013 as chief medical officer in the Center for Food Safety and Applied Nutrition and senior public health adviser to Mr. Taylor. Prior to that, he was deputy director of the National Center for Infectious Diseases at the Centers for Disease Control and Prevention (C.D.C.), and was director of the Bureau of Epidemiology and Acting Physician General at the Pennsylvania Department of Health. He graduated from the University of Pennsylvania of Medicine and completed residencies in internal medicine at the University of Colorado Health Sciences Center and in preventive medicine at the C.D.C.
