Neogen's 24-hour GeneQuence® Salmonella Test Receives AOAC status

GeneQuence Automated Food Pathogen Detection

Neogen Corporation has received Official Method status from AOAC International for its 24-hour GeneQuence® Salmonella diagnostic test system.

GeneQuence Salmonella combines the superior specificity of DNA hybridization technology with the ability to rapidly process up to 372 samples at once using a fully automated method, or a small number of samples via a non-automated approach.

While the GeneQuence Salmonella test system holds an AOAC-RI approval for a 48-hour turnaround, this new method (Official MethodSM 2007.02) reflects the use of Neogen's new 24-hour Salmonella enrichment protocol for select foods.

"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. We expect no less, and neither should our customers," said Ed Bradley, Neogen's vice president for Food Safety. "The GeneQuence test was shown to produce accurate results in only 24 hours, as opposed to other test systems that can take 48 hours or longer. Compared to other rapid methods, this is the lowest cost per data point of any DNA-based pathogen assay, due to its simplicity. Our customer commitment is clearly reflected in the technologies we offer. We add value to the customer via simple, specific, and scalable diagnostic solutions."

In a 15-laboratory collaboration study, 24-hour GeneQuence Salmonella was proven to be an effective test method to rapidly detect the pathogen in food products, such as poultry, eggs, milk chocolate, and dry pet food. In each case, samples were tested using the GeneQuence 24-hour protocol, and either the USDA-FSIS or FDA-BAM reference method, and results compared.

A major advantage of GeneQuence's DNA hybridization technology is its highly-specific probes, which virtually eliminate false negatives and greatly minimize the chance of receiving false positive results due to cross-reactivity with closely-related organisms. This specificity helps eliminate needless confirmation effort, and cost, and helps streamline a company's safety and quality processes. This specificity, coupled with the speed of results, allows companies to ship product sooner with greater confidence, thereby improving their supply chain efficiencies and lowering overall costs.

Neogen recently received Performance TestedSM Method status from the AOAC Research Institute for its new 24-hour environmental sample protocol for Listeria. Neogen's approved new enrichment protocol is for use with either its Reveal® for Listeria lateral flow assay or GeneQuence Listeria microwell DNA probe assay. Both of Neogen's test systems for Listeria had earlier gained AOAC status (Reveal #9607901, GeneQuence #010403); in both cases this new approval reflects the modification of the enrichment of environmental samples with Neogen's new LESS 24-hour single-step Listeria medium.
