摘要:Bio-security related to animal agriculture is a high priority issue, and recent incidents demonstrate the potential for disease transmission and proliferation involving animals exhibited at public venues. Data collected at the California State Fair and eight county fairs in the north central region of California were used to assess existing bio-security risks associated with 4-H project animals. Outcomes revealed disease transmission risks associated with exhibition practices including housing and visitor contact and highlight the need to develop and provide relevant education resources to 4-H youth, volunteers, and staff.
