Maintaining food safety and hygiene standards is top priority and challenge for farmers, food industries, governments and food technologists working in the food supply chain. Pesticides, toxins, veterinary drug residues, foodborne pathogens and many other harmful chemicals that may be present in a vast array of food products, due to various stages of their production like packaging and transport, constitute a global health problem that requires powerful and innovative technologies allowing constant and accurate detection of food products from production to consumption. Recent progress in generation of specific synthetic oligonucleotides against food contaminants has provided a new insight into the current sensor technologies, where these functional synthetic oligonucleotides, so-called aptamers, have been successfully combined with nanomaterials for rapid and cost-effective detection of several substances related to the food contamination, such as antibiotics, mycotoxins, heavy metals, carcinogenic dyes, pesticides, pathogens and other plastic products used for food packaging. Unique characteristics of aptamers over antibodies, such as in vitro selection, chemical and thermal stability, small size and ease of labeling have laid the solid foundation for exploring aptamers further in multiplexed food monitoring systems. In this chapter, we reviewed the application of aptamer-conjugated nanomaterials in food safety surveillance as well as the conventional techniques used for food safety monitoring in order to provide a comprehensive and comparative approach.
