This project will integrate core objectives of three strategic initiatives. It addresses the need for a safe food supply through targeted research on pathogenic zoonotic bacteria and parasites designed to reduce the risk of disease transmission from animals to 4-H youth who raise food animals and the public attendees of fairs and exhibitions. The project also aims to reduce inadvertent microbial contamination of food products among young producers who interface with commercial agriculture via fairs and exhibitions (Sustainable Food Systems Initiative [SFS]). Additionally, the project aims to decrease the risk of exposure to diseases that impact livestock productivity and to introduce best practices for risk mitigation through innovative outreach to young producers (Initiative for Managing Endemic and Invasive Pests and Diseases [EIPD]). Finally, the project aims to advance scientific literacy through engagement of 4-H youth members in the 4-H Bio-Security Proficiencies Program, an education program that has demonstrated positive effects on youth’s knowledge and skills (Healthy Families and Communities Initiative [HFC]). 4-H adult volunteers will be engaged through effective professional development strategies designed to build their capacity as science educators.
