24-hour aerobic bacteria indicator test
3M Food Safety has launched the 3M Petrifilm Rapid Aerobic Count Plate with AOAC-PTM approval
St. Paul, Minn. – 3M has launched the 3M Petrifilm Rapid Aerobic Count Plate, the next generation of its trusted, accurate and easy test that can detect aerobic bacteria counts in 24 hours for most food matrices.
The company says the 3M Petrifilm Rapid Aerobic Count Plate is proven to be as reliable as Standard Methods Agar. It also offers
• a faster time-to-result,
• a technology that reduces the impact of spreader colonies, and
• a simplified inoculation area to drive greater efficiency and reduce costly retesting and delayed results.
3M Petrifilm Rapid Aerobic Count Plates also leverages a dual-sensing indicator technology for easy enumeration of colonies in raw material, in-process and finished product food testing as well as environmental air, swab or surface contact testing.
The new 3M Petrifilm Rapid Aerobic Count Plate has received certification from the AOAC International Performance Tested Methods program inserts. Specific studies performed as part of this certification involved comparison tests to the FDA BAM and USDa reference methods, along with robustness and lot-to-lot/stability testing.
The sample-ready system uses an easy three-step process: Inoculation, Incubation and Enumeration. The system contains nutrients, a coldwater-soluble gelling agent, and a dual-sensing indicator technology that facilitates colony enumeration for most food matrices. Incubation temperatures are 32° C or 35° C.
