PerkinElmer, Inc. has launched the PerkinElmer Solus Listeria monocytogenes (LM) ELISA Assay. This new offering will help high throughput food processors and contract labs focus on LM testing for food and environmental surface samples. In sync with leading industry standards, the new solution is being introduced with Performance Tested MethodSM (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 20–30 percent* mortality rate if contracted by pregnant women, those over 65, or people with compromised immune systems (*Source:

The PerkinElmer Solus LM assay detects this harmful bacteria with accuracy, specificity, and convenience, especially for geographic regions whose regulations require separate reporting for LM.

Simplifying workflows, 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. A simple 24-hour + 24-hour enrichment process leverages supplemented standard media and incubation parameters are shared across matrices. 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,” says Greg Sears, vice president and general manager, food, PerkinElmer. “Our new Solus LM 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 LM assay, joins PerkinElmer’s foodborne pathogen portfolio including the wider spectrum Solus One Listeria assay, Solus One Salmonella, and Solus E. coli O157 ELISA. These innovations are part of the company’s broader food safety and quality solutions for grain, dairy, meats, produce, edible oils, seafood, and cannabis.
