As our leading nutrition providers, food supply chains have a responsibility to make sure the food we buy is fresh and healthy, not damaged or spoiled. So International Business Machines (IBM) created a freezer that detects when food items are reaching their expiration dates, according to Forbes.
The freezer uses Radio-Frequency Identification (RFID), which provides continuous temperature regulation of perishable foods. It can also alert staff when a certain item is low and needs to be restocked.
In 2011, President Obama signed the Food Safety Modernization Act (FSMA), which requires food regulators to be accountable for preventing contamination rather than just responding after the fact.
So new technologies like this freezer are being created to help food supply chains prevent contamination before it happens.
