Pack of 2 x Rapid Listeria Biofilm Detection Chemical Spray (INDICON GEL) - Ready to Use & Food Safe
Overview
Are you finding that despite a thorough cleaning regime, you are still getting positive swabs for Listeria and other pathogens? If so, it’s probably caused by the presence of Biofilms. The good news is – we can help detect and eradicate these!
Rapid Biofilm Detection
Indicon Gel provides a cost-effective, rapid visual indication of the presence of biofilm on a surface which may contain harmful microorganisms such as Listeria, Escherichia coli (E. coli) or Salmonella. When the product comes into contact with biofilm, Indicon Gel rapidly produces white micro-bubbles/foam within 2 minutes, providing a visual indicator of potential microbial harbourage sites.

Benefits
- Rapidly detect the presence of organisms living in biofilm harborage niches
- Simple to use spray bottle application
- Ready to use – simply point and spray
- Readily rinseable and non-staining
- Blue colour ensures reaction is visible on wide variety of surfaces
- Reaches areas a swab cannot reach
- Ideal for “seek and destroy”
- Use to track, train, and maintain
Listeria Monocytogenes
Biofilms of Listeria Monocytogenes on food contact surfaces have been identified as an important pathway for pathogenic persistence and subsequent product contamination, which is why traditional cleaning methods using caustic detergents followed by disinfection do not work; and why Enzyme detergents need to be used because they are capable of breaking the biofilm, allowing subsequent disinfection chemicals to kill the bacteria inside and remove the contamination source altogether.
“Hot spots” for Biofilms of Listeria monocytogenes are often found in the following locations:
- Floors
- Drains
- Trolley wheels
- Conveyor belts
- CIP systems (e.g. pipes)
- Complex machinery with lots of alcoves/crevice’s

I have Biofilms – what next?
If you identify Biofilms, you can either remove them through steam or mechanical action (i.e. scrubbing) BUT you must disinfect immediately to prevent the microbes from escaping the Biofilm and spreading around the factory. We recommend applying our Listeria Disinfectant immediately after Biofilm removal. CLICK HERE for more info.
Listeria on Floors / Drains?
Listeria contamination is commonly spread through wet floors, drains and high-traffic areas, where bacteria can survive and be transferred around the factory on footwear, wheels and equipment.
If your site suffers from persistent listeria on floors and drains, you need to trial our new Listeria & General Purpose Floor Disinfectant Granules called ProvaStep®.
ProvaStep is a ready-to-use dry disinfectant granule designed specifically for floor hygiene and can be used DURING production. The granules are applied directly to floors and remain inactive until they contact moisture already present in the environment. When activated, ProvaStep releases powerful hydrogen peroxide disinfectant to rapidly eliminate bacteria. This innovative moisture-activated technology allows food manufacturers to control Listeria on floors during production, without introducing additional water that can spread contamination or disrupt operations.
