The AUDFS Vision

The Detection and Food Safety Center will yield fundamental scientific advances in the methods of bacterial-chemical sensing, information technologies and integration of biological and electrical functions on a single chip. Results of these fundamental studies will be combined with engineering studies to yield enabling technology, such as handheld bacteria detectors, sampling methodologies and RFID sensor tags.

A range of industrial products are envisioned, beginning with bulk-food shipment monitor for automatic inventory, temperature and time measurement; improved systems for inventory-traceability (RFID tags); port-of-entry food inspection monitors; food processing monitors; and a continuum of inventory, temperature, bacterial sensor tags for bulk to individual packages.

STag sensorWith a cost of five to 10 cents, stamp-sized sensor tags (STags) can be placed on appropriate fresh-food products. With a target sensitivity of tens of cells, the sensors would transmit a host of information by non-line-of-sight radio frequency. For consumer safety, these sensors would measure temperature, bacteria count, and other chemical and environmental changes. For the food industry, these sensors would provide the same information, in addition to traceability features such as origin, date and time of processing, shipment information and a range of other "programmable" features. Our RFID STags would be found molded into the sides of plastic bottles, attached to the inside cap of glass bottles, molded into Styrofoam meat-trays and attached to plastic wraps.

Fulfilling the AUDFS vision will produce deliverables, such as:

  • Technology to instantaneously evaluate food safety at "port-of-entry" inspection stations
  • Technology to ascertain the presence of ruminant meat-and-bone-meal (MBM) in agricultural feed, thereby preventing bovine spongiform encephalopathy (BSE) from infiltrating the food-supply chain
  • Technology to monitor food processing lines and warn of possible contamination, thereby allowing processing parameters to be corrected
  • Technology to automatically inventory and instantaneously identify, warn and trace to the source potential problems (i.e., improper storage temperature occurring during distribution and shipment)
  • A new generation of engineers/scientists educated in systems-driven, team-based problem-solving with depth from both specific knowledge and traditional disciplines of engineering and biology, and capable of addressing and resolving complex issues in the food industry
