In 2007, USDA introduced a new set of food packages via an Interim Rule based on recommendations from the Institute of Medicine, which were implemented by October 2009. The contents of the food packages were finalized via a Final Rule in 2014. The Final Rule clarified some provisions in the Interim Rule and allowed some additional options and substitutions.

At the request of the U.S. Department of Agriculture, an expert Institute of Medicine (IOM) committee is undertaking a comprehensive review of the food packages used in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) to bring the program into alignment with current dietary guidelines. In this letter report, the first of three reports to result from this review, the IOM committee evaluates the 2009 regulation that excluded white potatoes from purchase with the WIC cash value voucher (CVV) and considers whether white potatoes should henceforth be allowed as a WIC-eligible vegetable in the CVV.

The WIC Participant and Program Characteristics 2012: Food Package Report is a supplement to the WIC Participant and Program Characteristics 2012 biennial report. The Food Package Report describes the content of WIC food packages based on information on the packages or prescriptions issued to WIC participants in April 2012. This report is a new report and should be of interest to researchers at USDA, academics, and others who study or have interest in the WIC program and nutrition.

This study developed innovative approaches to using nutrition labeling systems to incentivize healthy food choices by SNAP participants in retail settings. The approaches consider opportunities for using Front of Package and shelf labeling systems across all food categories and retail settings.

The Improper Payments Information Act of 2002 requires all federal agencies to calculate the amount of erroneous payments in federal programs and to periodically conduct detailed assessments of vulnerable program components. This 2012 assessment of the family daycare homes component of CACFP provides a national estimate of the share of the roughly 125,000 participating FDCHs that are approved for an incorrect level of per meal reimbursement, or reimbursement "tier" for their circumstances. 

This report estimates the average monthly food costs for each of 5 WIC participant subgroups and estimates total dollars spent on 17 major categories of WIC-eligible foods in FY 2010. The participant and food level costs in this report are USDA’s first estimates since implementation of the 2009 WIC food package changes.

Trafficking of SNAP benefits occurs when SNAP recipients sell their benefits for cash to food retailers, often at a discount. Although trafficking does not increase costs to the federal government, it is a diversion of program benefits from their intended purpose of helping low-income families access a nutritious diet. This report, the latest in a series of periodic analyses, provides estimates of the extent of trafficking during the period 2009 through 2011.

This report provides improper payment estimates for fiscal year 2011 using a methodology for “aging” the 2005 bookend study. The methodology yields nationally representative estimates of the number of vendors that over- and undercharged and the amount of over- and undercharges across all WIC vendors.

In 2006, FNS asked the Institute of Medicine to review the WIC food packages. The IOM proposed major changes to improve nutrition and encourage breastfeeding but also expressed the concern that changes related to partial breastfeeding may have unintended consequences. The IOM recommended that FNS conduct an impact study evaluating the birth month breastfeeding changes to the WIC food packages. 

This study describes some of the choices state agencies made as they exercised the flexibility offered during the implementation and describes the resulting food packages.
