Some time ago, I wrote about antimicrobial coatings in the Food Industry ("Antimicrobial Surfaces in the Food Industry", New Food, 2, 52-56, 2006). Applications in the bottling plant and for treatment of water coolers are now a cost-effective reality. Applied by spray, these treatments provide constant protection against bacterial growth on many types of surfaces within the bottling plant, particularly those areas susceptible to mould growth.
In addition, treatment of door handles or plastic curtains will prevent growth and transfer of bacteria from these surfaces. The spray should be applied onto a clean, dry surface and allowed to dry. The product will continue to suppress bacterial growth and mould growth for an extended period. Areas within the bottling plant where the product may be used are on ceilings and in corners where mould growth usually occurs, on the cap chute and in the machine above the filler head.
Consider treatment of taps or buttons on watercoolers and also drip trays and cup holders. An obvious application is in toilets for treatment of door handles and taps. A version of the product is available with detergent included, for easy sanitisation of smaller surfaces, such as cooler casings and fountains.
This technology was originally devised for a hospital environment, but application into the food and beverage industries soon followed. Application in bottling plants and for water coolers is a logical next step. One word of caution, application of this product does not mean that you can forget all other cleaning and disinfection in the bottling plant or the water cooler clean room. It should always be considered as a second line of defence to complement other hygiene measures in your due diligence regime.
