ST. PAUL, Minn. -- January 30, 2013

3M Food Safety today announced its 3M™ Molecular Detection Assay Listeria
method has received a matrix extension for select foods through the AOAC
Research Institute’s Performance Tested Methods^SM Program from the AOAC
Research Institute.

An expansion of the prior PTM certification from AOAC-RI (PTM Certification
#081203) , 3M™ Molecular Detection Assay Listeria method is now certified for
the detection of Listeria spp. in select food matrices, providing greater
applicability of the method for food and beverage processors. In recent years,
several large outbreaks of listeriosis have been linked to contaminated
manufactured foods ranging from vegetables to milk to meat.

The matrix extension of AOAC-PTM status required a rigorous, independent
laboratory examination of 3M’s unique molecular test method’s ability to
accurately detect Listeria spp. within a variety of intentionally contaminated
food matrices. Select food matrices specifically analyzed during the testing
process included cantaloupe, spinach, cottage cheese, beef hot dogs,
deli-style turkey meat and cold, smoked salmon. No statistically significant
differences were found in the sample results between the 3M Molecular
Detection Assay Listeria when compared to conventional reference methods.

“We’re pleased with the 3M™ Molecular Detection System’s steady performance
evaluating Listeria spp., particularly given that this bacteria is notorious
for multiplying even at low temperature points,” said Niki Montgomery, 3M Food
Safety global marketing manager. “The reliability and robustness of this
patented technology is continuing to serve and meet the needs of the
processing industry.”

The 3M Molecular Detection System is based on unique isothermal DNA
amplification and bioluminescence detection technologies and is designed
around modern-day food processors’ needs for a real-time pathogen detection
approach that’s faster and simpler while also more accurate. The company now
has AOAC-PTM validations for compatible assays designed for E.coli O157
(including H7) and Salmonella as well as Listeria.
