Systems and methods for monitoring conditions that affect the quality of food being served. Conditions such as temperature and elapsed time affect the quality of food and the safety of food consumers. Various embodiments of monitoring systems can be incorporated with different types of food containers. Sensors such as temperature probes can provide temperature information about the container and/or the food being served. The monitoring system can use such information in conjunction with elapsed time information in various ways. The monitored information can be displayed generally “real-time,” or it can be stored for subsequent analysis. The monitored information can also be used to trigger an alarm or similar indicator when a condition detrimental to food-serving is present. Various embodiments of the monitoring system having such features can be packaged in various embodiments, including a self-contained unit and an assembly of modular components linked by wire and/or wireless connections.
