Life Technologies LNO for pathogen detection device
Life Technologies has received a Letter of No Objection for its RapidFiner STEC detection system, which it claims detects the presence of multiple strains of E.coli in raw beef in 10 hours.

The turnaround time reduces the US Department of Agriculture (USDA) Food Safety Inspection Service (FSIS) guidebook standard of six days.

Life Technologies collaborated with the USDA to develop a test to detect E.coli O157:H7, and later expanded the project to the "Big 6" non-O157 strains (O26, O45, O103, O111, O121 and O145).

The validated system can clear negative beef samples (375 grams), and identifying presumptive positives in the same sample run with an additional hour of testing, said the firm.

The solution can detect one to five colony-forming units of pathogenic STEC in a single sample.

"The more strains of E.coli that meat producers can quickly and accurately analyze, the more likely they can ensure that beef is safe for public consumption,"​ said Nir Nimrodi, Vice president and general manager of Food Safety and Animal Health.
