PerkinElmer launches Solus Listeria monocytogenes ELISA assay

The company said it will help high throughput food processors and contract labs focus on L. mono testing for food and environmental surface samples.

In sync with leading industry standards, the new solution is being introduced with Performance Tested Method SM (PTM) certification from AOAC INTERNATIONAL (Association of Official Analytical Collaboration).

Though Listeria makes fewer people sick than other foodborne pathogens, the presence of the bacteria is more pervasive and Listeriosis carries a 20 to 30% mortality rate if contracted by pregnant women, those over 65, or people with compromised immune systems.

The company said the PerkinElmer Solus L. mono assay detects this harmful bacterium with accuracy, specificity and convenience, especially for geographic regions whose regulations require separate reporting for L. mono.

The new assay features the ability to employ a single protocol for both food samples (such as unpasteurized cheeses, meats, shrimp and vegetables) as well as environmental sample swabs and sponges. Users can choose to process samples manually or automate them with Dynex Technologies’ DS-2 system.

“Listeria is a concern for food processors and consumers because it can live anywhere and can create lethal illness,”​ said Greg Sears, vice president and general manager, food, PerkinElmer.

“Our new Solus L. mono assay with AOAC PTM certification helps labs and processors be even more vigilant and precise in detecting and fighting back against this challenge to the global food chain.”​

The new Solus L. mono assay joins PerkinElmer’s foodborne pathogen portfolio including the wider spectrum Solus One Listeria assay, Solus One Salmonella, and Solus E. coli O157 ELISA.

The innovations are part of the company’s broader food safety and quality solutions for dairy, grain meats, produce, edible oils, seafood, and cannabis.
