Evaluating biocides for surface decontamination
Following the lowering of the maximum residue levels for Quaternary Ammonium Compounds* in foods, the search is underway for alternative biocides. We have launched a new service to evaluate their effectiveness in the microbial decontamination of food contact surfaces.
We can simulate real-life scenarios in our microbiology process hall to test the effectiveness of biocide alternatives in the decontamination of equipment and food surfaces from pathogenic and other microorganisms.
Matrices such as food debris, fat, oil and grease can be applied to surfaces to enable decontamination in real-life scenarios to be simulated and tested - generating meaningful quantitative data. Equipment and product manufacturers can also get their equipment individually assessed with us.
Joy Gaze, Head of the Heat Resistance and Decontamination Group said, “We can simulate conditions that are specific to a manufacturing site – from surface materials, to combinations of bacteria, even the type of food that will build up on the equipment – providing assurance and confidence that the product and the way it is applied will decontaminate effectively.”
