The paper presents simulation results to be used for improved design of a portable short time response bio-sensor device dedicated to dairy industry for early detection of possible infestation with pathogen bacteria Escherichia coli and/or other micro-organisms in milk. A two-component model was developed: the first component is defined on computational biochemistry basis and refers to the quantitative definition of life cycle of bacteria or other type of micro-organisms while the second optimizes the constitutive characteristics of the Long Period Grating Fiber Sensors. The model predicts the modifications of the refractive index of the milk due to the presence of the bacteria and provides information about its concentration..
