Claim 11:
12. A hygiene monitoring system comprising:
a radio frequency (RF) tag for storing an identifier of an opened food container which will be attached to the opened food container upon opening the food container by a user;
a machine comprising an RF tag reader and a processor, wherein the machine is located proximate to a compartment storing a food container,
a first database for storing a list of food types and food-specific safe consumption period corresponding to each food type for consuming food of such food type stored in the food container after opening the food container, and
a second database for storing a list of RF tag identifiers along with expiration date of the food in the corresponding opened food container;
wherein said processor is configured to automatically generate a set of food expiration information for the food stored in the food container when the user scans the RF tag of the opened food container with the RF tag reader, and
wherein said set of food expiration information comprising:
an expiration date calculated based on a food-specific safe consumption period from said list of food type and a first current date indicating when the food container is being opened by the user; and
wherein said food-specific safe consumption period is retrieved from said first database based on a specified food type communicated to the processor by the user; and

wherein the processor updates the identifier of the scanned RF tag and the calculated expiration date into the second database.
