Applied Markets Watch: Instant Labs Listeria Test; DuPont Salmonella Assay

Premium

InstantLabs Medical Diagnostics said this week that its Listeria species food safety kit for the Hunter Accelerated Real-time PCR System has received AOAC Performance Tested Methods certification for environmental and food matrices.

InstantLabs' kit has been certified for the identification of Listeria species in foods and environmental surfaces that are common carriers of the potentially lethal foodborne pathogen. The award follows independent laboratory studies conducted by Food Safety Net Services. The AOAC Performance Tested certification mark is widely recognized by the food industry and government agencies and is awarded to products that have passed unbiased and rigorous evaluation.


The DuPont BAX System assay for detecting Salmonella has been recognized as an AOAC Official Method of Analysis, DuPont Nutrition & Health said this week.

The BAX System uses PCR and real-time detection to deliver results, DuPont said. Building on previous certification of Performance Tested certification by the AOAC Research Institute, the OMA validation studies demonstrated consistent reliability and repeatability of the BAX System method when testing for Salmonella in a variety of food types such as meat and seafood, beef trim, poultry and eggs, dairy products, produce, cocoa, pepper, and infant formula; as well as pet food and environmental samples.
