FNS uses a set of EBT-based administrative tools and undercover investigations to identify and sanction trafficking retailers, and to estimate the extent of trafficking. The estimates of the amount of trafficking, the trafficking rate, and the store violation rate reported here are based on information from almost 33,000 stores subject to administrative or undercover investigation from late 2002 through 2005.

The purpose of this report is to illustrate the types and amounts of foods being prescribed within the WIC food package for each category of participants. This report does not provide information on redemption of the food prescriptions, or on actual food consumption; at this time, comprehensive data are available only on food prescriptions.

This is a report of the National Academies' Institute of Medicine (Food and Nutrition Board), published here by permission. It is also available on the Institute of Medicine website. In response to many concerns about the WIC food packages, FNS asked the Institute of Medicine to conduct a review of the WIC food packages.
