In fiscal year 2001, school meal programs provided lunch, breakfast, and snacks to over 27 million school children daily. For those outbreaks with a known cause, the most commonly identified cause of the illnesses were foods contaminated with salmonella or Norwalk-like viruses. To evaluate the trend in the number of school outbreaks, and in their number relative to non-school outbreaks, we compared the observed numbers to the estimated numbers of school and non-school outbreaks.This analysis shows that there is an upward trend in foodborne illness outbreaks reported in schools between 1990 and 1999 and that not all of this increasing trend is attributable to changes that took place when CDC began a more active data collection effort. The other 7 outbreaks were not linked to foods served in the school meal programs, but with foods brought to schools from home or other sources. Therefore, data limitations make it difficult to assert with complete certainty to what extent the foods served in the school meal programs are the cause of the reported outbreaks from 1990 to 1999. However, as we stated most recently in our October 2001 testimony, the existing food safety system is a patchwork structure that hampers efforts to adequately address existing and emerging food safety risks whether those risks involve inadvertent or deliberate contamination.
Why GAO Did This Study

The national school lunch and breakfast programs provide inexpensive or free meals to more than 27 million children each day. During the 1990s, nearly 300 outbreaks of foodborne illness at the nation's schools sickened 16,000 students. The rise in the number of school outbreaks mirrors a rise in the number of outbreaks in the overall population, according to the Centers for Disease Control and Prevention (CDC). Because the CDC data include outbreaks attributable to food brought from home or other sources, GAO could not determine the extent to which food served in the school meal programs caused reported outbreaks. Data from 1998 and 1999 do show, however, that most of the outbreaks during those years were caused by foods served through the school meal program. Foods contaminated with salmonella and Norwalk-like viruses were the most common causes of outbreaks.

What GAO Found

GAO found that the Department of Agriculture has not developed security measures to protect foods served at schools from deliberate contamination. The existing food safety system is a patchwork of protections that fall short in addressing existing and emerging food safety threats.
