Veriflow® Listeria species assay (Veriflow® LS) has been approved to detect bacterial contamination by listeria in various food types, including ready-to-eat foods, deli meat and dairy products, and on various surfaces with which food comes into contact during preparation and packaging. The assay utilizes a PCR detection method coupled with a vertical-flow-based assay. It requires only 24 hours of non-specialized incubation for maximum sensitivity and develops in 3 minutes post PCR amplification. The product eliminates the need for cumbersome sample-preparation steps, gel electrophoresis or fluorophore-based detection of target amplifications.
