Improvement of the safety of food handling practices on small farms

Improvement of the safety of food handling practices on small farms

Summary

In the past year we have collected samples of fresh produce being sold at farmers markets within 3 regions of South Carolina (Coastal, Midlands, Upstate). Produce samples were enumerated for total aerobic organisms and coliforms and these data are still being analyzed to determine if there are regional, seasonal or product effects in bacterial levels. Members of the research team (a faculty and graduate student) gave presentations at two GAPs training session in the state in cooperation with the SC Department of Agriculture. A consumer and farmer survey has been developed which will be administered in the coming year. The survey objective is to determine consumer expectations and misconception about locally grown produce and producers beliefs on how to market their product. In the next year we plan to conduct on-farm audits to determine potential process steps most susceptible to product contamination.

Objectives/Performance Targets

The goal of this project is to identify risk factors for food safety in the processing of specialty crops on small farms and to develop more effective and targeted interventions for foodborne illness prevention. We propose four objectives to accomplish this goal: 1. To develop a more complete characterization of food handling, hygiene, and sanitation practices that contribute to foodborne illness by conducting observations of harvest and packing practices on small farms in the SE US. 2. To collect and analyze microbiological samples from the hands of farm workers and surfaces (harvest bins, processing belts, produce) at these same farms. 3. To identify foodborne illness risk factors and effective control strategies using the findings from the observations and microbiological testing results. 4. To develop, deliver, evaluate, and disseminate training interventions targeting farm managers based on identified risk factors and control strategies to increase their competency in delivering educational messages to farm workers.

Accomplishments/Milestones

We have completed data collection of produce samples from farmers markets located in different parts of South Carolina. A survey tool has been developed to determine consumer perceptions of locally-grown produce and this survey has been tested on students and staff at the university. A survey for small farmers has also been developed and all surveys have been approved by the university internal review board for human subjects. Members of the SARE project team have given presentations at two GAPs training workshops in cooperation with the SC Department of Agriculture.

Impacts and Contributions/Outcomes

The proposed research will fill gaps in our current knowledge regarding risk factors for foodborne illness on small farms. We will use findings from the observational and microbiological analysis to develop targeted training interventions. Unlike other educational materials that have been developed, the materials will be targeted to food safety educators so that they are equipped with the required knowledge and competency to deliver messages on food safety to small farmers. Thus, it is expected that small farm workers will exhibit safer practices following educational efforts and thus help reduce the risk for foodborne illness.
