Presentation Description:

Microbial challenge testing for pet foods: new models – Pet foods and treats continue trending toward all-natural, minimally processed, fewer/no preservatives and functional ingredients, making natural preservatives an attractive alternative to synthetic ones. However, they require rigorous evaluation to establish their efficacy in pet foods. Microbial challenge studies are a useful way to assess a preservative’s ability to extend the shelf life and enhance the safety and quality of diets, treats and raw materials, but challenge testing in pet food products involves unique considerations. Find out why, plus the factors influencing microbial survival, criteria for choosing microorganisms, inoculum form, concentrations and suitable analytical methods.

Experience:

At Kemin Nutrisurance, the pet food and rendering technologies division of Kemin Industries, Burke focuses on developing natural products to prevent spoilage and reduce risk of microbial contamination in pet foods, treats and ingredients, and in developing methods to evaluate their effectiveness. She has over 19 years of experience in microbiology, food safety, animal health and method development. Prior to joining Kemin, Burke was employed with Intervet, developing vaccines for animal health to prevent diseases caused by bacterial pathogens. She received her bachelor of science in microbiology and immunology from Iowa State University.
