Kiril Mischeff, a leading UK supplier of fresh vegetables to ready-to-eat (RTE) manufacturers, is committed to high compromising food safety standards. Despite rigorous hygiene protocols, the facility faced persistent Listeria contamination on processing floors—posing a serious risk to compliance and customer trust. To address this challenge, Sterilex introduced ProvaStep, the UK’s first granular dry disinfectant, engineered to deliver continuous protection and minimise cross-contamination risks in high-traffic areas.
Even with intensive wet cleaning routines, Kiril Mischeff’s aging, porous flooring provided an ideal environment for Listeria to thrive, resulting in occasional positive samples. With a full flooring replacement scheduled for the future, the company needed an immediate, effective, and non-disruptive solution to safeguard production and maintain compliance with stringent food safety requirements.
"ProvaStep was recommended by our largest customer who was seeing good results themselves, with Sterilex onsite for the initial application, we were quickly able to implement its use. The results were beyond our expectations; this is superb product.” Paul Hocking, Technical Manager at Kiril Mischeff
Sterilex recommended ProvaStep, a breakthrough granular dry disinfectant featuring a slow-release formulation that activates with minimal moisture. Unlike traditional wet disinfectants, ProvaStep:
o Targets contamination hotspots without adding excess water that can fuel microbial growth
o Provides long-lasting protection during and outside production hours
o Requires minimal training and integrates seamlessly into existing hygiene programs
The facility applied ProvaStep at mapped Listeria risk zones across the line floor for two consecutive weeks at the standard label rate of 100 g/m². The application process was simple and required minimal training, allowing staff to adopt the new protocol quickly without specialised equipment. ProvaStep was applied seamlessly during routine schedules, ensuring no operational disruption and full production continuity.
ProvaStep’s impact was immediate and measurable:
o 98% reduction in Listeria presence on tested floor areas.
o Significant labour savings by replacing 3–5 daily wet disinfectant applications with a single dry treatment.
o Water Conservation: Eliminated approximately 2,000 litres of water per day, supporting sustainability goals.
Facility leadership praised ProvaStep as a game-changing innovation, citing its unmatched efficacy, ease of use, and ability to optimize production efficiency while reinforcing food safety compliance.
ProvaStep demonstrated its ability to transform microbial control in food production. By achieving near-complete elimination of Listeria on the plant floor, Sterilex’s innovative granular dry disinfectant proved its effectiveness as a cutting-edge solution.
Beyond pathogen reduction, ProvaStep delivered measurable operational and business benefits:
o Efficiency Gains: Simplified hygiene workflows freed labour for higher-value tasks.
o Resource Optimisation: Transitioning to a dry application eliminated unnecessary water usage, reducing operational costs and supporting sustainability goals.
By combining technical efficacy with operational simplicity, ProvaStep enabled the facility to strengthen food safety compliance while advancing broader objectives in efficiency, sustainability, and production optimization—reinforcing its value as a comprehensive tool for modern food safety programs.
