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.
