To overcome food borne illness, food quality and safety are major scientific disciplines including food
handling, preparation and storage. Detection of contaminants in the food system is the main concern regarding public
health. It is necessary to develop an immunoassay system to detect and control food borne pathogens in contaminated
foods before they enter into the human food chain and cause infections. The conventional methods including agar plating,
chromatography or immunoassay are tedious and time consuming for detection of food contamination, while biosensors
are one option to overcome these problems. There is growing interest towards biosensors technology due to high
specificity, convenience and quick response. In the field of food science and technology, biosensors technology for the
detection of food borne pathogens is more fascinating to the current researchers. In this contest we introduce, quartz
crystal microbalance (QCM) a label free and piezoelectric biosensor for the detection of pathogenic microbes and toxins
present in the food. The potential significance of the present review is to provide the implementation of QCM based
biosensor for the detection of various analytes in food systems including toxic and nontoxic.
