Detection of undeclared animal by‐products in commercial canine canned foods: Comparative analyses by <scp>ELISA</scp> and <scp>PCR‐RFLP</scp> coupled with slab gel electrophoresis or capillary gel electrophoresis

Abstract

Significant disparities were evident between the labelled contents and the detected content of animal by-products. CGE-based testing for PCR products appears to provide greater sensitivity and accuracy than either SGE or ELISA-based methods. As testing of commercial products becomes more reliable and mainstream, manufacturers will need to develop more thorough and accurate labelling protocols.
