Pathogen and toxin-contaminated foods and beverages are a major source of illnesses, even death, and have a significant economic impact worldwide. Human health is always under a potential threat, including from biological warfare, due to these dangerous pathogens. The agricultural and food production chain consists of many steps such as harvesting, handling, processing, packaging, storage, distribution, preparation, and consumption. Each step is susceptible to threats of environmental contamination or failure to safeguard the processes. The production process can be controlled in the food and agricultural sector, where smart sensors can play a major role, ensuring greater food quality and safety by low cost, fast, reliable, and profitable methods of detection. Techniques for the detection of pathogens and toxins may vary in cost, size, and specificity, speed of response, sensitivity, and precision. Smart sensors can detect, analyse and quantify at molecular levels contents of different biological origin and ensure quality of foods against spiking with pesticides, fertilizers, dioxin, modified organisms, anti-nutrients, allergens, drugs and so on. This paper reviews different methodologies to detect pathogens and toxins in foods and beverages.

“…The Griess reaction is considered for the reduction of nitrate ions (Miranda et al 2001). Ion chromatography (Dudwadkar et al 2013), optical fibre sensors (Ensafi and Amini 2012;Pellerin et al 2013), planar electrode sensors (Wang et al 2015), ion-selective electrodes (Schazmann and Diamond 2007), palladium nanostructures (Pham et al 2014) are some of the techniques that are used to measure nitrate ions in water. Even though the techniques mentioned above have been successfully validated, most of them are laboratory-based and create a lot of chemical waste, which has detrimental effects on the environment.…”

This chapter explains the fabrication and implementation of sensor patches developed from laser-induced polymer films. Photothermal induction of commercial films was done to form graphene that was subsequently used as electrodes in sensor patches via transferring them on sticky tapes. The sensor patches were used for different environmental and industrial applications like salinity sensing, taste sensing, and nitrate sensing.
