Neogen has received approval from the AOAC Research Institute for a test to detect E. coli O157:H7 DNA.

The ANSR for E. coli O157:H7 detects the bacteria after 10 minutes of reaction time following sample preparation.

It is an isothermal amplification reaction test method that amplifies the DNA of any target bacteria present in samples to detectable levels.

Neogen's pathogen detection method can provide definitive results in 12 hours from the time the sample is taken with ANSR's single-step enrichment.

The test has been validated for testing raw ground beef, raw beef trim, leafy greens and sprout irrigation water.

Ed Bradley, Neogen's vice president for food safety, said validation provides further assurance to customers that tests perform as expected/

"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." 

Neogen also announced a program for its ANSR rapid pathogen detection system. It is a limited-time 30-day trial for an on-site evaluation of the ANSR system using any or all ANSR assays. 

Neogen's line of ANSR products also includes AOAC Research Institute-approved tests for Salmonella, Listeria and Listeria monocytogenes.
