IBM has begun the development of tiny AI sensors capable of sensing pathogens on food. Between the harvest of a product, and the arrival of it on the shelf, there is plenty of time for bacteria to contaminate said product. Within the next five years, IBM predicts that their technology could put a stopper in bacterial pollution.
The optical sensors pick up wavelengths of substances and infer microscopic details about them, including the presence of pathogenic bacteria. The sensors can be utilised throughout the supply chain, all the way through until the food is in the consumer's hands. Pioneering technology like this unlocks limitless possibilities, and the general increase of food safety would be a significant relief to many areas of the world.
