Produce Growers' On-Farm Food Safety Education: A Review

Abstract

Abstract: From planting to distribution, fresh produce can be contaminated by humans, water, animals, soil, equipment, and the environment. Produce growers play an essential role in managing and minimizing on-farm food safety risks. Because of an increase in public awareness about produce safety, farmer food safety education has become an important research and extension topic. This review article summarizes findings by researchers who have evaluated produce growers' food safety knowledge and attitudes and the effectiveness of food safety educational programs for growers. A search of on-line databases, journal archives, conference abstracts, and reference lists of relevant studies was conducted to locate peer-reviewed articles on produce growers' food safety knowledge and behavioral changes. Study selection criteria included publications in English, publication between 2000 and 2019, and a focus on one of six topics: handling of agricultural water, soil amendments, domesticated animal and wildlife management, worker health and hygiene, food safety plans and record-keeping, and cleaning and sanitation. Forty-three published articles were included in the analysis. Handling of agricultural water and soil amendments were the two topics least understood by growers, whereas worker health and hygiene were the best understood. Food safety educational interventions were evaluated in 13 studies, and most studies used in-person workshops and self-reported pre- and postintervention knowledge assessments. Most reported increased knowledge, some reported improved attitudes and perceived behavioral control, and only four reported behavioral changes. Because of small sample sizes, many studies did not include a statistical analysis of the differences between pre- and postintervention survey results. This review article provides insights and guidance for the development of food safety education for produce growers.
