Intelligent refrigerators have additional tools against food poisoning

With the laser tool developed by researchers at the Korea Institute for Advanced Industrial Science and Technology, users can eliminate the risk of dangerous infections when using food in the refrigerator.

If you think the refrigerator is a clean place, you're wrong. Food can be infested before being put into the refrigerator, or even infected in the refrigerator. In the United States alone, about 50 million cases of food-borne infections occur each year. Three thousand of them had to be hospitalized with severe digestive disorders affecting their lives.

New laser devices can detect bacterial movements without the need for food projection. Just measuring the density of samples and analyzing the time, temperature and presence of living organisms has yielded accurate results.

To test the effectiveness of the laser, Dr. Jonghee Yoon and the team gave E. coli and Bacillus, two of the main agents that contaminated food, into the kitchen. They observed that the device detected both types of dangerous bacteria.

The next step for the team is to develop a mechanism and a way to kill dangerous bacteria, also by laser, but at a stronger level.
