Biofilms are complex microbial ecosystems formed by one or more species immersed in a combination of different arrangements depending on the type of manufacturing environment they live within. Examples of microorganisms that can make up these biofilms include bacteria and fungi.
Detecting biofilms, bacteria and other pathogens in the food, beverage, and pharmaceutical process industry is forever a challenge. When using the ATP swabbing system a contaminated area can be missed by millimeters. Food manufacturing plants, particularly sanitation and food safety/quality personnel, want to recognize this potential hazard as quickly as possible, as biofilms can have a profound impact on the safety and quality of their products and the end consumer. Biofilm formation can contaminate products through the introduction of pathogenic microorganisms or spoilage bacteria. They are difficult to highlight and are often resistant to normal cleaning procedures. Even when a surface appears to be clean, the presence of biofilms is a potential hazard that must be detected, eliminated, and prevented from reoccurring.
Using the BioDtex Lamp from Bioscan LTD in conjunction with ATP swabbing reduces the risk considerably by instantly highlighting the potential critical area. With then the ability to capture the image and take accurate ATP samples for lab testing.
BioDtex utilises engineered UV-A light technology to bounce UV light off stainless steel surfaces, to expose harmful microorganisms such as Listeria, Salmonella, E. coli, Pseudomonads, and Yeast (see Table 1). The UV-A frequency used by BioDtex works on the upper fringe of the UV spectrum and allows the light to target key protein cells that grow
on bacteria, yeast, and moulds.
Ensure all high touch areas are clean and free of contamination before production commences by simply scanning the surface with the BioDtex UV lamp. BioDtex UV lamp can illuminate large areas of work surfaces, aseptic lines, tanks, cheese vats, and other vessels, ensuring clean areas are adhering to the highest standards.
