Progress in sensory devices of pesticides, pathogens, coronavirus, and chemical additives and hazards in food assessment: Food safety concerns

Food intake gives vitality and supplements to support humans and other living organisms. Food safety and contamination problems associated with food hygiene, storage, chemical additives, enzymes, bacteria, and pesticides are crucial issues because of their direct influence on the health of humans and even animals. New monitoring technologies should be developed for potential food safety and significant environmental benefits. To date, the ultrasensing, early detection, and real- and on-time monitoring of vital reactive species, biomolecules, chemicals, and hazardous agents are important in ensuring food quality. With significant advances in the engineering of sensory devices, the progressive development of accurate quantity screening, early explicit monitoring and assessment, and real-time detection analysis can support the standard food quality through the full control of an extraordinary food safety test. Progress in numerous autoexamining appraisals, sensing protocols, and tools of (i) reactive species and chemical additives associated with human metabolism and various nutritional and industrial processes of foods, including ascorbic acid (AA), H2O2, uric acid (UA), and nitrite and sulfite anions; (ii) extremely organic and inorganic hazards such as heavy metals and bisphenol A; and (iii) food adulteration, pesticides, pathogenic microorganisms are a key challenge for food safety concerns. To date, evidence supporting the possibility of transmitting coronavirus disease 2019 (COVID-19) infection through food products is unavailable. However, in a report on an outbreak in mid-June 2020 in China, food contamination with the causative agent of COVID-19 pandemic, SARS-CoV-2, was discovered. Thus, sensory protocol devices for monitoring the SARS-CoV-2 antigen associated with food products is urgently needed for the future perspective progress in health. As such, we provide details in advanced sensor development in the monitoring, analysis, and evaluation sectors for food safety applications. We also report on next-generation nano/microscale wearable sensor devices that can wirelessly provide relevant healthy and safety food information data. This review gives evidence that the powerful engineering of mobile food sensor devices is an ongoing acquisition, offering considerable future avenues to the perspective in-home healthcare of aging individuals.
