Authorized by the 2014 Farm Bill, the USDA Pilot Project for Procurement of Unprocessed Fruits and Vegetables was designed to provide states with additional flexibility in the procurement of unprocessed fruits and vegetables. Participating states and school food authorities can purchase approved items with existing USDA Foods National School Lunch Program entitlement funds from any USDA Pilot-authorized vendor in support of the school meal standards.

In 1991 and 1998, FNS conducted national studies of WIC vendors to determine the extent of vendor violation of program rules. After the 1998 study, FNS issued regulations to correct vendor practices. The 2005 study replicates the 1998 study to determine whether the regulations were effective, and to measure the frequency of vendor violations and the degree to which vendors charge accurate prices for WIC transactions.
