Biosensors encompass the whole range of analytical instruments which can be associated intimately with a biological component for the target recognition step. It have several advantages over other methods of analysis, including real-time detection, portability, multianalytes determination for both on-site and laboratory analysis. The development of biosensors for real-time identification of multiple bacterial pathogens in food remains a challenge for ensuring food safety. Successful applications of sensors developed for analysis of food borne pathogens, including E. coli, Staphylococcus aureus, Salmonella and Listeria monocytogenes will be presented in this lecture. Biosensors can also be used for rapid evaluation of cleaning effectiveness as part of good manufacturing practices and HACCP programs. Experimental results obtained exclusively in our laboratory or in collaboration with known international laboratories involved in food safety will be presented and discussed. Indeed, analytical performances of sensors for toxins, phenols, bisphenol A, heavy metals, pesticides, acrylamide and drug residues at trace levels will be presented and highlighted. Special attention needs to be focused on the complexity of food samples. Indeed, turbidity of the sample will affect optical methods while salts concentration will have a major impact on electrochemical methods. Although rapid and sensitive biosensors for industrial food applications are reported in literature, simple biosensors used by non skilled persons are still required in the market.
