It can happen every day, and it can happen to almost any manufacturing facility or product in every city, state, town and country around the world. When was the last time YOU experienced it? When was the last time you experienced a microbiological contamination issue? Did your product smell, was it gassing, did it change color, produce a drop in pH, or display several of these noticeable changes? The microorganism, the oldest living creature on Earth is the cause of all these problems. If you were to simply ignore the symptoms of microbial growth in your facility or product, then the diagnosis would be biodeterioration. The rate of biodeterioration will depend on prevailing environmental conditions and the types of microorganisms involved; bacteria, yeast and/or mold. There are many control measures that can be taken to prevent and/or correct biodeterioration. These include, specific microbiological control methodologies, and the use of biocides within a manufacturing facility.
