WILMINGTON, Del.—DuPont Nutrition & Health debuts its DuPont™ BAX® System Real-Time PCR Assay for Genus Listeria, a next-generation test that combines shorter, simpler sample preparation and faster real-time processing, without sacrificing accuracy or reliability.

The assay can be used as a quick and reliable method for detecting Listeria in a variety of products and has been validated on frankfurters, cooked shrimp, spinach, queso fresco cheese and environmental surfaces. The assay provides additional flexibility by allowing customers to test for both Listeria and Salmonella in the same batch, with results for both organisms in a little over an hour.

“Listeria species can be an indicator that harmful Listeria monocytogenes is present, which can cause serious illness, particularly for persons with heightened susceptibility," said Rob McPheeters, diagnostics leader, DuPont Nutrition & Health. “This new assay demonstrates our commitment to providing the best value in science-based solutions for evolving food protection needs to help producers and manufacturers significantly reduce this risk."
