Abstract
A method for discriminating between contaminated and uncontaminated containers prior to washing is disclosed characterized by the testing of the residue of the container to determine if the residue is residue of the original product packed in the container. If the residue is not sufficiently similar to the original product, the container is rejected as contaminated.
