Evaluation of ENVIRO-KIT™, a new device for rapid detection of Listeria monocytogenes on food contact surfaces.

Listeria contamination remains a significant food safety concern, particularly within food manufacturing environments. This study evaluated the performance of ENVIRO-KIT™ LISTERIA, a rapid detection kit comprising a pre-moistened swab and liquid indicator medium, designed to detect Listeria spp., including pathogenic Listeria monocytogenes, on environmental surfaces. Testing demonstrated a clear colour change from straw to black in samples containing Listeria within 24–48 hours of incubation at 37°C. Non-target bacteria showed no colour change, demonstrating the selectivity of the medium and its potential to reduce false-positive results.
