 You've probably searched for a recipe on your phone, but pretty soon your phone will be able to detect something much more sophisticated bacteria IBM researchers are building artificial intelligence and cell phone sensors that will identify bacteria as small as one micron That's about 75 times smaller than a single human hair, but sensors won't just be on our phones Counters and cutting boards could be equipped with sensors as well This technology will pop up way earlier in the food chain Bacteria sensors could be put on farm tractors They might be found in food packing plants or inside shipping containers even in the produce aisle these sensors will be everywhere Our food is soon when you make a salad your only concern will be getting your kids to actually eat it
