U.S. Secretary of Agriculture Brooke Rollins, in a brief announcement unveiling new staff hires on Monday, released a blurb about Kelsey Barnes, her recently appointed senior advisor. Barnes is a former lobbyist for Syngenta, the Chinese state-owned giant that manufactures and sells a number of controversial pesticide products. Syngenta's atrazine-based herbicides, for instance, is banned in much of the world yet is widely used in American agriculture. It is linked to birth defects, low sperm quality, irregular menstrual cycles, and other fertility problems. The leadership of USDA is filled with personnel with similar backgrounds. Scott Hutchins, the undersecretary for research, is a former Dow Chemical executive at the firm's pesticide division. Kailee Tkacz Buller, Rollins's chief of staff, previously worked as the president of the National Oilseed Processors Association and Edible Oil Producers Association, groups that lobby for corn and other seed oil subsidies. Critics have long warned that industry influence at the USDA creates inherent conflicts of interest, undermining the agency's regulatory mission and public health mandates. The revolving door hires also highlight renewed tension with the "Make America Healthy Again" agenda promised by Health and Human Services Secretary Robert F. Kennedy, Jr. The 2025-2030 Dietary Guidelines for Americans may serve as a test of whether establishment industry influence at the agencies will undermine MAHA promises.
