You’ve likely heard of the mysterious entities known as “black holes” – NASA as well as many scientists worldwide share a theory that black holes in space literally constitute holes in the observable universe from which nothing can ever escape. Any matter that encounters them will be pulled inward by their massive gravity, destroyed and lost to the universe forever.
Here on Earth and until recently, the black hole for destroying airborne cross-contamination in the food processing environment remained elusive using traditional technologies such as fiber filtration. “State of the art” HEPA-fiber filtration was developed for the America’s Nuclear Manhattan Project just before the end of WW II – and yes, some 66 years ago. Through the years, chemical applications and even toxic gases have been offered as solutions.
We all know and readily accept state-of-the-art sanitizers and disinfectants to clean our floors, filter air, treat processing equipment, wash hands, etc. Unfortunately, it is instinctive to disregard what we cannot see, touch, smell or hear; including the ever present flow of airborne cross-contamination of microorganisms and organics as they fall into our products and onto our cleaned surfaces.
