title: Comparative validation study to demonstrate the equivalence of a minor modification to AOAC Method 997.03 [Visual Immunoprecipitate (VIP) for Listeria] to the reference culture methods.
abstract: The Visual Immunoprecipitate (VIP) for the Detection of Listeria in Foods and Environmental Surfaces, AOAC Official Method 997.03, has been modified to use a simplified housing for the device. A methods comparison study was conducted to demonstrate the equivalence of this modification to the reference culture methods. Two food matrixes and one environmental surface were analyzed. In total, valid results were obtained from 145 samples and controls. Results showed that the modified VIP for Listeria spp. is equivalent to the reference culture methods for the detection of Listeria.
