LANSING, Mich., Dec. 9, 2015 /PRNewswire/ -- Neogen has received approval from the AOAC Research Institute for its new rapid and accurate test to definitively detect E. coli O157:H7 DNA.

Neogen's newly approved ANSR^® for E. coli O157:H7 detects the bacteria after only 10 minutes of reaction time following sample preparation. Neogen's ANSR is an isothermal amplification reaction test method that exponentially amplifies the DNA of any target bacteria present in samples to detectable levels.

"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 Ed Bradley, Neogen's vice president for Food Safety. "ANSR is the fastest DNA-definitive pathogen assay available — with results in only 10 minutes. Compared to the three hours other methods such as polymerase chain reaction, or PCR, take to produce DNA-level results, that's a huge difference in a laboratory's workflow, and the operations of a food producer as a whole."

Combined with ANSR's single-step enrichment, Neogen's new pathogen detection method for E. coli O157:H7 can provide definitive results in as little as 12 hours from the time the sample is taken. To date, the test has been validated for testing raw ground beef, raw beef trim, leafy greens and sprout irrigation water.

With the validation of ANSR for E. coli O157:H7, Neogen also announced a new program for its ANSR rapid pathogen detection system. The program is a limited-time, risk-free 30-day trial for an on-site evaluation of the ANSR system using any or all of Neogen's ANSR assays. The program is designed to show prospective, qualified food laboratories how easy rapid molecular pathogen testing can be.

Neogen's line of ANSR products also includes AOAC Research Institute-approved tests for Salmonella, Listeria and Listeria monocytogenes. The ANSR system was designed to combine molecular-level accuracy with a scalable, low-cost instrument and a methodology that can be easily incorporated into any testing laboratory's existing workflow.
