QIAGEN achieves AOAC certification of automated workflows for detection of Listeria pathogens in common foods

  • mericon® Pathogen Detection Assays for Listeria species and Listeria monocytogenes contamination of foods gain AOAC Performance Tested MethodSM certifications
  • Food safety laboratories can run mericon Listeria kits manually or on QIAGEN’s flexible, efficient QIAsymphony Rotor-Gene Q (RGQ) automation platforms
  • AOAC certifications for mericon Listeria tests follow validation of mericon Salmonella species kit and further strengthen QIAGEN’s broad offering for food safety

Hilden, Germany, and Germantown, Maryland, November 20, 2014 – QIAGEN today announced that its mericon® Pathogen Detection Assays for Listeria species and Listeria monocytogenes received AOAC Performance Tested MethodSM (PTM) certification from the AOAC-Research Institute. The AOAC, an independent third party international organization that evaluates analytical methods for food safety and other applications, validated the two assays with single enrichment in selected foods from meat, seafood, fruit/vegetable and dairy sectors, and in environmental tests on common food production surfaces. The AOAC evaluation assures food companies and laboratories that QIAGEN’s mericon kits and the QIAsymphony RGQ automation platform have been demonstrated to reliably detect Listeria spp. (PTM #061402) and L. monocytogenes (PTM #061401) in various food matrices and environmental surfaces.

Contamination of produce and other foods with Listeria monocytogenes and related bacterial species can cause serious, life-threatening infections. The Centers for Disease Control, calling listeriosis “an important public health problem,” estimates the invasive infection sickens about 1,600 people in the U.S. and causes an annual average of about 260 deaths. In 2011, the largest single U.S. outbreak – associated with cantaloupe from one farm – caused 147 persons to become ill, caused 33 deaths and one miscarriage. Older adults, pregnant women, newborns and adults with weakened immune systems are most vulnerable.

“QIAGEN is addressing the critical needs of today’s food safety market with a broad range of pathogen detection assays and an efficient and complete workflow on our renowned QIAsymphony RGQ automation platform. This now AOAC-PTMSM-validated mericon assay platform for Listeria offers food producers and laboratories an important solution for protecting food from contamination with this dangerous pathogen,” said Dr. Dietrich Hauffe, Senior Vice President, Life Sciences Business Area. “We are very pleased to add Listeria to our content menu with the AOAC-certified mericon Salmonella Pathogen Detection Kit. The mericon assay platform represents the broadest portfolio on the market providing highly sensitive and specific molecular detection of pathogen nucleic acids for users safeguarding the food supply chain. Ready-to-use pathogen detection kits combined with the QIAsymphony RGQ automation enable users to process over 400 samples in a 12-hour shift.”

Highly flexible and scalable, QIAGEN’s food safety product line addresses every stage of the workflow, from automated extraction to target detection. QIAGEN expects to seek additional AOAC certifications for a range of pathogen assays, such as E. coli O157 and Campylobacter. In addition to PCR-based detection of pathogens, QIAGEN provides systems for the identification and quantification of DNA from genetically modified organisms (GMOs) and for the authentication of important ingredients.


QIAGEN N.V., a Netherlands-based holding company, is the leading global provider of Sample & Assay Technologies that are used to transform biological materials into valuable molecular information. Sample technologies are used to isolate and process DNA, RNA and proteins from biological samples such as blood or tissue. Assay technologies are then used to make these isolated biomolecules visible and ready for interpretation. QIAGEN markets more than 500 products around the world, selling both consumable kits and automation systems to customers through four customer classes: Molecular Diagnostics (human healthcare), Applied Testing (forensics, veterinary testing and food safety), Pharma (pharmaceutical and biotechnology companies) and Academia (life sciences research). As of September 30, 2014, QIAGEN employed approximately 4,200 people in over 35 locations worldwide. Further information can be found at http://www.qiagen.com.
