Leanne Skelton

 

Produce Safety Staff, on Detail from USDA, Senior Policy Analyst

Ms. Skelton is currently on an extended detail assignment from the U.S. Department of Agriculture with the Produce Safety Staff.  In this capacity, she is working on produce safety rule development and efforts aimed at supporting the rule.  Other activities include developing strategies for outreach, education and communication, engaging other Federal and State partners, and developing approaches to the related compliance, inspection and enforcement policies.  Ms. Skelton brings over 25 years of experience with the fresh fruit and vegetable program area at USDA, where she is on staff with the Fruit and Vegetable Program area within the Agricultural Marketing Service.  Prior to this detail assignment, Ms. Skelton was Chief of the Fresh Products Branch. Ms. Skelton began her career with the New York State Department of Agriculture and Markets as a Farm Products Inspector.
Ms. Skelton holds a Bachelor of Science degree from the School of Agriculture and Life Sciences, Cornell University.  After college, she was a Peace Corps volunteer, working as an agricultural research officer in the Cook Islands.

"This detail assignment bridges the food safety gap between two distinct mission areas; FDA’s -- protecting and promoting public health, and AMS’ -- to facilitate the competitive and efficient marketing of agricultural products.  It enhances the working relationship between USDA and FDA on this important issue.  In food safety, everyone shares responsibility – from the farmer to the consumer and all points in between.  At FDA we also have a responsibility to recognize and consider existing programs and good practices farmers and packing houses are already implementing as we move forward on this rule and related initiatives.”
