Predictive microbiology

Predictive Microbiology is the area of food microbiology where controlling factors in foods and responses of pathogenic and spoilage microorganisms are quantified and modelled by mathematical equations [1]

It is based on the thesis that microorganisms' growth and environment are reproducible, and can be modeled.[2][3] Temperature, pH and water activity impact bacterial behavior. These factors can be changed to control food spoilage.[4]

Models can be used to predict pathogen growth in foods. Models are developed in several steps including design, development, validation, and production of an interface to display results.[4] Models can be classified attending to their objective in primary models (describing bacterial growth), secondary models (describing factors affecting bacterial growth) or tertiary models (computer software programs) [5]
