3M Food Safety Awarded AOAC Certification for Water Microbial Testing Tool

3M Petrifilm Aqua Coliform Count Plates have received Performance Tested Method (PTM) validation (Certification Number 091101) from the AOAC Research Institute. 3M Food Safety recently introduced this technology for enhancing productivity, consistency and ease-of-use in microbial testing of bottled water.

 

Validation studies compared 3M Petrifilm Aqua Coliform Count Plates to reference method 9222 B2a of the American Public Health Association (APHA) Standard Methods for the Examination of Water and Wastewater. The AOAC PTM certified 3M Petrifilm Aqua Coliform Count Plates to be equivalent to or better than the reference method for the enumeration of Coliforms, a contaminant that jeopardizes water and beverage bottling industry products.

 

The testing, completed by an independent laboratory as part of the AOAC Research Institute’s validation process, follows and confirms an earlier third-party test commissioned by 3M Food Safety last year that compared to ISO 9308-1, the U.S. FDA Bacteriological Analytical Manual (BAM) and the Standard Methods for the Examination of Water & Wastewater. The tests also concluded that the 3M Petrifilm Aqua Coliform Count Plates performed equivalent to or better than the reference methods.  

 

3M’s new test method provides an alternative to water testing methods such as those that involve media pads, disposable filter funnels, and agar petri dishes. 3M states that industry analysis in 292 food processing plants demonstrated an 80 percent increase in technician productivity (tests per hour) by switching from traditional agar to the sample-ready, compact, and shelf-stable 3M Petrifilm plates. 

 

“The convenience, ease-of-use and storage-saving attributes of 3M Petrifilm Aqua Plates are significant.  Receiving certification from an organization as highly respected as the AOAC Research Institute is extremely helpful in conveying our product’s strong and consistent performance,” said Bob Jechorek, regulatory affairs specialist with 3M Food Safety.
