RFID systems can be used to ensure that food products such as meat, fruit, and dairy products remain within a safe temperature range during transportation and storage. VarioSens® RFID tag from KSW Microtech AG (Dresden, Germany) can function as a temperature datalogger and as a supply-chain tracking tool. The range of operation for this datalogger is from −20 to 50 °C. Turbotag™ from Sealed air (Elmwood Park, N.J., U.S.A.) is another temperature monitoring RFID tag, which captures and delivers the temperature history of any product to which it is tagged.

ThermAssureRF™ from evidencia (Memphis, Tenn., U.S.A.) is a new RFID-based datalogging system that combines tracking and tracing with temperature measurement. Combining RFID and temperature logging tags provides the processors with a means of, complying with Hazard Analysis and Critical Control Point (HACCP) requirements. ThermAssureRF can also track goods throughout the supply chain. This temperature logger is currently being used by a variety of companies that ship wine, produce, seafood, meat, poultry, pharmaceuticals, and cosmetics (ElAmin 2007).

Auburn Univ. Detection and Food Safety (AUDFS) project combines RFID technology with sensors for detection of pathogens in food. The goal of this project was to coat microscopic structures with bacteriophages or viruses that bind with pathogens. When a pathogen binds with the coating, a signal will be transmitted to a handheld RFID reader (Nambi and others 2003).
