Idaho Technology said today that two additional matrices for its PCR-based Salmonella test have received Performance Tested Method approval from AOAC International.
Idaho Tech, based in Salt Lake City, Utah, received approval for stainless steel environmental samples and pet food. These join a list of already-approved matrices for use in the company's Salmonella LT kit, run on the RAPID LT Food Security System.
The assay uses real-time PCR to identify the presence of Salmonella in less than one hour after a pre-enrichment period, Idaho Tech said.
The RAPID LT Food Security System is built upon Idaho Tech's LightCycler technology, and combines rapid air thermocycling and real-time fluorimetry to test food and environmental samples.
"We have developed an easy, accurate, and timely PCR assay for detecting Salmonella in food and on surfaces," Kristine Clemens, a food safety validation manager at Idaho Tech, said in a statement. "We are thrilled to add these critical matrices to our AOAC approval, giving companies even more testing options."
Other approved matrices for the Salmonella LT kit include chocolate, cooked ham, fresh raw chicken, lettuce, raw ground beef, and liquid whole eggs, Idaho Tech said.
