Carl K. Winter

Specialist in the Cooperative Extension


Ph. D. University of California at Davis, 1987


Dr. Winter researches the detection of pesticides and naturally-occurring toxins in foods, how to assess their risks and identify how to use the science in the regulatory decision-making process. His most recent work includes looking at the relationships between crop production systems and naturally-occurring toxins. He also studies how to improve educational activities through incorporation of music into food safety curricula.
