WILMINGTON, Del. – DuPont Nutrition & Health announced it will introduce the company's BAX System Real-Time PCR Assay for Genus Listeria at the Food Safety Summit in Baltimore, Md., April 8-10.

The new assay has been validated for frankfurters, cooked shrimp, spinach, queso fresco cheese and environmental surfaces, the company noted. The assay also allows testers to check for Listeria and Salmonella in the same batch with results completed for both pathogens in 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.”
