As reported by multiple outlets, Stephen Ostroff, FDA’s Deputy Commissioner for Food and Veterinary Medicine, will retire January 5. Ostroff assumed the role of Deputy Commissioner in 2016, previously serving as the acting FDA Commissioner on two occasions. Walmart’s Vice President for Food Safety and Health, Frank Yiannas, is set to replace Ostroff.

Yiannas will have a different title, Deputy Commissioner for Food Policy and Response, reflecting FDA’s ongoing efforts to reorganize the agency. The agency is planning to create a new office focused on food safety, the Office of Food Policy and Response, which will advance the Food Safety Modernization Act work and coordinate foodborne illness outbreak response.

However, Yiannas’ role will not be limited to food safety. In an email announcement to staff, FDA Commissioner Scott Gottlieb reportedly said of Yiannas, “we’re delighted to be welcoming Frank to FDA and believe his extensive expertise in supply chain security can help inform our work across our different product areas, including food but also when it comes to the safety and security of medical products.” These changes come amid increased attention on FDA over food recallsand Gottlieb’s pledges to reform the agency’s approach.
