The SDIX RapidChek Listeria FAST (Fast Accurate Sensitive Technology) environmental test system can be used for the detection of Listeria species on environmental surfaces and is suitable for use by the ready-to-eat meal sector.
The system provides results in 24 h. Other rapid methods require a 24 h or longer enrichment followed by further sample processing and assay time that leads to a time-to-result of 26-32 h. With this system, results are achieved within 15 min of enrichment.
Processors can now take their programs from ‘test and hold’ to ‘test and sold’ by reducing time-to-result while still maintaining highly accurate results.
The system is claimed to have 100% specificity and sensitivity against inclusivity and exclusivity panels tested. These panels included organisms spanning all six species of Listeria and several non-Listeria, Gram-positive organisms. The system is also claimed to be equivalent to the regulatory, 48 h cultural method for the detection of Listeria on various environmental surfaces.
The system detects all six species of Listeria for a complete solution for environmental monitoring programs. Missing a single species of Listeria in an environmental monitoring plan reduces knowledge of potential growth niches and possible contamination areas.
SDIX’s world-class detection device is based on advanced immunoassay technology that is used in several health-related diagnostics worldwide. SDIX, one of the largest and most trusted producers of antibodies in the US, produces its own antibodies that are exclusive to the RapidChek test systems.
The detector is based on advanced immunoassay technology and the company produces antibodies exclusive to the RapidChek test systems. The unique media along with the advanced immunodetection device allow for good resuscitation of stressed or injured cells and better selectivity against non-target organisms, leading to faster and more accurate results.
The test system is AOAC approved and validated for use on various environmental surfaces such as stainless steel, painted concrete, rubber, and plastic.
