The ANSR for Listeria gained the Performance Tested Method Certification (PTM #101202) from the AOAC Research Institute.
Additional matrixes include pasteurized milk and liquid egg, Mexican-style cheese, ice cream, smoked salmon, lettuce, cantaloupe and guacamole.
"Each time we receive a validation from an influential third party on any of our tests, it provides further assurance to our many customers that our tests perform as expected," said Neogen's Kristen Antonellis.
"This matrix extension is in response to customer requests, as we continue to work with our customers to provide the best pathogen testing options available."
The ANSR system uses a isothermal DNA process to amplify DNA to detectable levels and fluorescent molecular beacon technology for pathogen detection.
Combined with ANSR's single enrichment step, Neogen claim their method can provide DNA-definitive results for Listeria in 16 hours from the time the sample is taken.
Unlike PCR-based methods, ANSR requires only a single reaction temperature, which eliminates the heating and cooling cycles of older methods.
