When Sonny Perdue took over the Department of Agriculture last April, he vowed to “work tirelessly to solve the issues facing our farm families.” Given his past, plenty of critics doubted they’d like his solutions, but it was too premature for anything but hand-wringing. However, Perdue has now run the USDA for about a year. The Union of Concerned Scientists, a 200,000-member-strong science-advocacy group, dutifully tracked his changes over the last 12 months, and has just published them in a new report called “Betrayal at the USDA.” It outlines the myriad ways the agency has “sidelined science, undermined key public health and safety protections, and prioritized the interests of large agribusiness companies over the public interest.”
