A new PCR yeast and mold test that provides results in just four hours is available for finished dairy products. Developed by Germany-based Biotecon Diagnostics, the foolproof yeast and mold quantification test has demonstrated 100% specificity with 290 strains, representing 260 species with all phylogenetic groups included, according to a release from Weber Scientific. It also demonstrated 100% exclusivity with 60 strains of non-target microorganisms typically found in similar ecological niches (Sensitivity is 101 – 102 cells / g depending on sample type).
“This test is based on well-established real-time PCR technology,” said Phil Coombs, product specialist at Weber Scientific. “There is a high degree of correlation between conventional methods and PCR. Results are displayed in CFU per gram and only viable organisms are detected…The real cost benefits will be achieved by how much more quickly can product be shipped and how many recalls avoided.”
