The firm said Listeria monocytogenes is a notable public health concern due to its ability to cause serious infection if a person eats contaminated food.
Rob McPheeters, Diagnostics global business leader, DuPont Nutrition & Health, said this increased concern has focused attention on the need for well-validated pathogen detection methods in the food processing environment.
“At DuPont Diagnostics, we are proud to offer a variety of validated PCR assays to help food manufacturers, service laboratories and retailers detect L. monocytogenes and other Listeria strains with speed, accuracy and reliability in a way that best fits a company’s workflow.”
Additional validations are in progress for PCR assays to detect E. coli O157:H7 and Listeria species.
