E-coli is one of the most dangerous agents of food-borne disease and ingesting contaminated food or water can be deadly. But I just read that experts from the University of California Los Angeles have come up with a device that can put a mobile phone to use fighting food-borne sickness. The gadget, which is only a prototype, utilizes LED and ultraviolet lights to identify E. coli bacteria. Source for this article: UCLA scientists create E coli detector attachment for cell phones. This is a big help for us in preventing this bacteria since E. coli can easily contaminate food and drinking water and it poses a significant threat to public health.
