Sensors for food safety management have the potential to greatly improve the safety of people’s diet. As we continue to pollute the environment our food continues to be affected, directly and indirectly. Whether it's by high amounts of microplastics, high levels of mercury or other harmful metals, or another toxic substance, the potential for our food to have unsafe contaminants is increasing. If pathogens, spoilage microorganisms, microbial communities, and toxins are detected early on in the food supply chain, foods with these harmful components will never reach the mouths of people. If widely implemented the effects of sensors for food safety will be broad-reaching and will ultimately improve global dietary health.
