Crystal Diagnostics (CDx) Xpress System has received certification for Salmonella on whole uncut tomatoes and whole chicken rinsate when at levels of 1 colony-forming unit (cfu) per sample.
The system combines liquid crystal technology with antibody-coated paramagnetic microspheres to capture and detect Salmonella from food matrixes.
CDx is already accredited by AOAC for detection of E. coli O157 and the “Big 6” STECs.
Jim Bruce, CDx president and CEO, said: “The company is quickly expanding our portfolio of target pathogens and food types with our rapid and accurate liquid crystal biosensors.”
Bruce added it expects to have AOAC accreditation for Listeria in June and an AOAC certified 12-hour Salmonella test by yearend, covering a range of food types.
Jay Hardy, founder of Hardy Diagnostics, the national distributor of Crystal Diagnostics’ products, said a 15-hour sample-to-result Salmonella test was unimaginable just a year ago.
“To be able to offer this unique detection system incorporating such speed and accuracy keeps our customers on the leading edge of food safety technology.”
Crystal Diagnostics is the exclusive licensee of liquid crystal technologies developed through a research partnership between Kent State University and Northeast Ohio Medical University.
