Abstract/Summary:
Since the colonial era, farmers in the U. S. have utilized a constantly changing system of markets to barter, sell, and distribute their farmed goods to the local populace. Today, farmers' markets have replaced old-world style markets providing more than just local produce. Since the late 1970's, farmers' markets in the U. S. have experienced an exponential growth with over 8,200 farmers' markets operating in the U. S. today. As farmers' markets have increased in size, scope, and complexity in the kinds of foods sold at these venues, so has the potential food safety risks. Today, farmers' markets provide thousands of farmers in Pennsylvania and hundreds of thousands in the U. S. an economic opportunity to sell their agricultural products outside of the conventional commercial markets, while also allowing them control during harvesting, processing, packaging, transportation, and final sale of their products, from farm to fork.;While the economic and social impacts of farmers' markets are no doubt important and positive, previous observational, survey, and microbiological research of farmers' markets in various regions of North American have revealed that in many cases, farmers' market vendors can lack important knowledge and experience in food safety practices and behaviors. These studies have also observed vendors performing high-risk retail food safety behaviors, and identified the presence of both hygiene indicator and pathogenic bacteria on select produce, meat, and dairy products. Throughout the past decade, numerous outbreaks and recalls associated with farmers' market sold food products also have been reported, further highlighting the food safety implications of farmers' markets. While these incidents have yet to cause mass public illness or capture national media attention, there is a great potential for a single food safety incident to jeopardize the farmers' market movement, toppling a billion dollar industry endangering the livelihoods of hundreds of thousands of farmers' in the U. S., and causing illnesses and potential deaths of consumers.;To date, several studies have evaluated specific elements of farmers' market food safety, such as consumer preferences and vendor behaviors, however no one study has used multiple research tools to identify food safety gaps in the same setting. Training programs for farmers' market vendors also have been developed, however, current available programs may not be focused specifically on food safety, may not be validated scientifically, and content may not be based on actual farmers' market vendor needs. To date, no current training program has been developed to address the specific and unique needs of Pennsylvanian farmers' markets and vendors. Therefore the purpose of this study is to assess the unique food safety issues related to farmers' markets and vendors in Pennsylvania through a comprehensive food safety needs assessment, and based on the results, develop and pilot-test a new customized food safety training program for farmers' market vendors in Pennsylvania.;The comprehensive food safety assessment was accomplished using five tools: 1) the use of direct concealed observations of farmers' market vendors in the retail setting; 2) farmers' market vendor exploratory, knowledge and attitudinal surveys; 3) Pennsylvania Department of Agriculture inspector observational surveys; 4) market manager structured group interviews; and 5) microbiological sampling and analysis of produce, beef, and pork products obtained from Pennsylvania farmers' markets. An overall comparison and compilation of results from each research tool identified key risk factors and gaps in food safety knowledge, attitudes, and behaviors. Specifically, the microbiological assessment demonstrated that a proportion of select produce and meat obtained from farmers' markets in Pennsylvania was of questionable microbiological quality, due to the presence of fecal coliforms, E. coli, and Listeria spp. Further analysis also suggested that E. coli isolated from meat and produce had unique phylotypic properties and few isolates exhibited potential pathogenic properties. Results of the observational and survey portions of the assessment revealed that a lack of knowledge and improper behaviors performed by vendors related to hand washing, glove use, thermometer use, packaging use, and cross-contamination, were important risk factors which could be addressed through education and training.;Based on those results, it was determined that food safety training for farmers' market vendors in Pennsylvania could address food safety knowledge and behavior gaps, potentially leading to safer foods sold at farmers' markets. Guided by the preferences collected from vendor surveys, the FDA Food Code, and applicable Pennsylvania food safety regulations, a training program consisting of a comprehensive food safety resource guide and associated interactive 3- hour PowerPoint presentation was developed and piloted in several cities across Pennsylvania. Using a pre- and post-test knowledge and attitudinal assessment, it was determined that the piloted training program produced significant increases in knowledge and positive changes in attitudes among vendor participants.
