CDx previously announced that it had been accredited by AOAC for detection of E. coli O157, Salmonella, and the “Big 6” STECs. According to CDx President and CEO Jim Bruce, “CDx is now ahead of schedule in expanding our portfolio of target pathogens and food types with our rapid and accurate liquid crystal biosensors. We will continue to add additional food-borne pathogens and food types in our offering of fast and reliable AOAC accredited tests.”

Dr. Matthew Taylor, Associate Professor of Food Microbiology, Texas A&M University, said that “Crystal Diagnostics is making significant inroads with the additional pathogen targets being added to its product line. My laboratory has recently instituted a funded study testing of beef samples utilizing the liquid crystal biosensors…results have been impressive.”

The Company has national distribution through Hardy Diagnostics and sales agreements with distributors in Central America and Australia.
