The BAX System 24E assays for detecting Listeria species and Listeria monocytogenes were developed with Oxoid Ltd. Validation studies on hot dogs, spinach, cooked shrimp queso fresco cheese and stainless steel showed the system performed as well or better than traditional culture methods, said the company. The system also provides a much quicker time to result.

“Coupled with the certification these assays have already received from AFNOR in Europe, this AOAC-RI validation provides customers with additional assurances of accuracy and reliability,” said Morgan Wallace, senior research microbiologist at DuPont Qualicon.
