Local Food Systems Food Safety Concerns.

Abstract

Foodborne disease causes an estimated 48 million illnesses and 3,000 deaths annually (Scallan E, et al., Emerg Infect Dis 17:7-15, 2011), with U.S. economic costs estimated at $152 billion to $1.4 trillion annually (Roberts T, Am J Agric Econ 89:1183-1188, 2007; Scharff RL, http://www.pewtrusts.org/en/research-and-analysis/reports/0001/01/01/healthrelated-costs-from-foodborne-illness-in-the-united-states, 2010). An increasing number of these illnesses are associated with fresh fruits and vegetables. An analysis of outbreaks from 1990 to 2003 found that 12% of outbreaks and 20% of outbreak-related illnesses were associated with produce (Klein S, Smith DeWaal CS, Center for Science in the Public Interest, https://cspinet.org/sites/default/files/attachment/ddreport.pdf, June 2008; Lynch M, Tauxe R, Hedberg C, Epidemiol Infect 137:307-315, 2009). These food safety problems have resulted in various stakeholders recommending the shift to a more preventative and risk-based food safety system. A modern risk-based food safety system takes a farm-to-fork preventative approach to food safety and relies on the proactive collection and analysis of data to better understand potential hazards and risk factors, to design and evaluate interventions, and to prioritize prevention efforts. Such a system focuses limited resources at the points in the food system with the likelihood of having greatest benefit to public health. As shared kitchens, food hubs, and local food systems such as community supported agriculture are becoming more prevalent throughout the United States, so are foodborne illness outbreaks at these locations. At these locations, many with limited resources, food safety methods of prevention are rarely the main focus. This lack of focus on food safety knowledge is why a growing number of foodborne illness outbreaks are occurring at these locations.
