3M launches fast Salmonella detection system
According to the Minnesota-based company, its Petrifilm Plates already are used throughout the industry, with 91 of the top 100 US food processing firms using them. The Petrifilm Salmonella Express System technology now is available around the globe.
Close collaboration
Mojdeh Poul, 3M Food Safety vice president and general management, has said the new technology is the product of close communication with food industry professionals.
“3M’s newly expanded portfolio of pathogen detection solutions represents our dedication to collaborate closely with the industry to deliver fast detection methods with accurate results,” he said.
The AOAC Research Institute has granted the system Performance Tested Method validation. The institute reportedly found the product to meet or exceed reference methods for testing raw ground chicken, beef and pork; pasteurized liquid whole egg; cooked chicken nuggets and other materials.
Fast results
The firm reports the new system provides a shorter time-to-result, more uniform results and a longer shelf life than the conventional agar methods. It provides detection and biochemical confirmation of Salmonella in enriched food and food process environmental samples, providing results faster than traditional agar methods.
The all-in-one method starts with the Petrifilm Salmonella Express Plate, a sample-ready chromogenic medium specific to Salmonella with a presumptive result. The Confirmation Disk has a substrate that facilitates biochemical confirmation of all presumptive positive Salmonella colonies on the platein just four hours.
Market demand and key advantages
Tina Baumann, global marketing supervisor with 3M Food Safety, told Food Production Daily that the market requires increasingly accurate, speedy results on pathogen tests.
“Increased regulation and prevalence of foodborne pathogens such as Salmonella have created a demand for new pathogen detection solutions that are accurate, fast, simple and affordable,” she said.
Baumann added that the Petrifilm Salmonella Express system offers a number of advantages over other testing products currently available.
"The 3M Petrifilm Salmonella Express System is unique in that it's an all-in-one test method that includes presumptive positive results and biochemical confirmation, in as little as 44 hours," she said. "Lab technicians can confirm all presumptive positive colonies on the plate at the same time, in as little as 4 hours, with out having to pick and transfer colonies. This is two times faster than most traditional methods."
The Petrifilm Salmonella Express System is the latest addition to the company’s pathogen detection portfolio. Other products include molecular, immunoassay and indicator testing methods, as well as DNA-based solutions.
