3M unveils innovative technology for rapid detection of foodborne pathogens
Tuesday 26 June 2012
3M’s Food Safety business has launched a fast, accurate and easy-to-use pathogen detection system.
The new 3M Molecular Detection System, based on an innovative combination of two technologies - isothermal DNA amplification and ATP bioluminescence – delivers highly sensitive results in a simple format.
Amplification and detection occur simultaneously and continuously during the exponential phase indicating the presence of target organism DNA in real time, giving positive results in as early as 15-20 minutes and negative results in 75 minutes.
Individual assays for Salmonella, E. coli 0157 (including H7) and Listeria are available in easy to distinguish colour coded kits. With ready-made reagents and only one test protocol for all target pathogens, the system is easy to use, allows for multiple pathogen detection during each run and reduces the chance for human error or contamination.
The technology has been evaluated with a variety of food types, including dairy produce, meats, processed foods, and food processing-related environmental samples.
Compact and portable with no need for recalibration after moving, the system is versatile and the software can run up to four instruments at a time to increase throughput. The technology avoids the need for complex, costly, high maintenance instrumentation and the system is robust and easy to clean.
“Food processors and contract labs now have the specificity and sensitivity required for pathogen detection without compromising on productivity,” said Damian Doherty, 3M Food Safety. “The accuracy and time to results of the Molecular Detection System are designed to help technicians make critical decisions faster, whilst protecting brands and ensuring public health.”
