Food Safety & Foodborne Disease Prevention

admin-ajax.php(1)

Overview

 

Our vision for the Department is to be the preeminent integrated (research,education, extension) food safety program, providing students and stakeholders with the capacity to analyze situations, address issues, and produce solutions that prevent contaminants in food and their adverse effects on human health.

 

 

Goals


  • Increase the knowledge and skills of students and stakeholders through excellence and innovation in food safety education and training programs.
  • Increase food safety and prevention outreach and service programs to students and stakeholders.
  • Position the department to have a greater role and influence in federal, state, and local food safety policy.
