Developing Food Safety Tools and Training for Organic Produce Farms | The Organic Center
Organic growers work diligently to meet the high demand for organic produce and protect consumers from foodborne illnesses. Yet many organic growers face serious obstacles in meeting both food safety requirements and USDA National Organic Program standards. According to a 2019 USDA Organic Survey, compliance with food safety regulations is one of the greatest challenges facing

Extending Knowledge on Biosecurity in Small-scale and Backyard Systems in the United States
Extending Knowledge on Biosecurity in Small-scale and Backyard Systems in the United States
The number of small-scale and backyard operations has increased in the United States during the past decade, but there is currently a lack of outreach efforts and readily-available educational materials targeting these farming systems. We developed a webinar series on biosecurity to provide training for small-scale and backyard producers, and training tools that can be used by local veterinarians and extension educators to disseminate knowledge and consistent recommendations more effectively. Fewer people attended the webinars than registered, suggesting a gap between interest in biosecurity and commitment to the topic. Participants in the webinar series reported a high level of satisfaction and a significant increase in knowledge.
