Abstract
Experts identified water quality, manure, good handling practices (including personal hygiene and equipment sanitation), and traceability as critical farm problem areas that, if addressed, are likely to decrease risk associated with microbial contamination of fresh produce from all scales of agriculture. However, the diverse nature of production strategies used by produce farmers presents multiple options for addressing foodborne illness issues while simultaneously creating potential complications. We use a mental models methodology to enhance our understanding of the underlying factors and assumptions of small, medium, and large produce growers that influence their decision-making processes for contamination prevention and control. This empirical evidence demonstrates how challenges and opportunities to food safety are related to the scale of production and marketing strategies. We believe that refining the development of standards and existing extension and outreach food safety programs are important to both consumer protection and supporting agricultural communities. Additionally, this approach will help develop and refine food safety programs that will result in empirically grounded recommendations based on identified grower information needs.

Notes
Farmers of produce refer to themselves as “growers.” Consequently, we use the self-labeled term “grower” when referring to produce farmers in our research.
Enterprises in this research are farms and scales that follow USDA ERS definitions for farm sizes: large farms have gross incomes over $500,000, medium farms are $100,000 to $499,000, and small farms are less than $100,000.
Traceability is not addressed in this research because it is an approach to surveillance of food safety contamination and not a source of on-farm food safety.
University Extension is part of the University Land Grant system responsible for communication and learning activities that engage the public.
The FDA will open the comment period for produce growing food safety rules with a draft set of rules in January 2012, and close it by April 2012. The final ruling will be adopted by April 2013 with full compliance among produce growers expected by April 2014 (Leanne Skelton, personal communication, 2011, Senior Policy Analyst in the USDA Center for Food safety and Applied Nutrition, Office of Food Safety).
Unpublished notes from the 2006 workshop. Farmers participating in the workshop contested the efficacy of various washing practices that are promoted by industry citing concerns that these practices lack sufficient scientific validation and if used alone are unlikely to eliminate contamination sources.
The expert panel included members with food safety expertise from the following groups: university produce scientists, animal health scientists and Extension specialists with regional expertise (University of Georgia, Kansas State University, University of Kentucky, Ohio State University, University of California at Davis); experts from the Center for Disease Control, USDA, FDA, and the Ohio Department of Agriculture; food safety officers from national grocers, retailers and marketers associations; large and small-scale produce growers; and inspectors and auditors from PrimusLabs, a national third party auditor.
There are three methodological challenges to a microbial detection in water used in the production of fresh produce (Ilic et al. 2010). First, lab conditions vary greatly across facilities and from real world conditions creating a problem of precision in testing. Second, there are differences in test quality resulting from using indicators species rather than target species, creating problems of accuracy. E.g., testing for total coliforms as an indicator is considerably less expensive than testing for E. coli OH157, a major human pathogen. Additionally, in lieu of a test metric developed for food safety, the metric currently used (235 MPN/100 ml of water) was developed by the USEPA to establish safe swimming waters (USEPA 2003). Third, tracing contamination from farm to fork is increasingly difficult in large commodity chain networks.
