FreshLoc Technologies, Inc., Plano, Tex., an innovator in wireless food safety technology, and Ecolab, Inc., St. Paul, Minn., a leader in food industry sanitation, announced on May 11 a strategic alliance to solve or prevent food safety problems by use of the FreshLoc automatic data-collection, monitoring, and alerting system.
Wireless sensors monitor temperature, humidity, and other environmental data and transmit the data via the Internet for access by management at any location via computer, telephone, cellular phone, pager, or fax. Several times a minute, the sensor transmits a unique identity number and the current conditions existing at the sensor’s location to a reader/antenna located nearby (up to about one-third of a mile indoors or a quarter of a mile outdoors), which forwards the information to a secure, Internet-based monitoring system. The system logs and reports the temperature data coming in from each sensor, 24 hours a day. Reports can be generated at intervals prescribed by management and in real time. When data are outside tolerance levels, the system automatically alerts management, so prompt corrective action can be taken.
According to Doug Foster (phone 972-423-3313), FreshLoc’s President and Chief Operating Officer, the sensors (see photo) are about the size of three stacked quarters and slightly larger in diameter than a half-dollar and can be placed in as many or few locations as desired. They are powered by internal batteries and have a life of two years if set to transmit 2–4 measurements per minute and up to 3½ years if less-frequent measurements are required. They can measure temperature, humidity, vibration, and other things, even if they are not built into the actual circuit. For example, a sensor can take data from a gas-sensing meter and relay that information over the Internet. The sensors were first used in beta-testing trials two years ago, Foster said, and have been used in field trials by about 30 companies since then.
In the alliance, FreshLoc Technologies will provide the sensor technology, systems, and technical support, as well as ongoing tracking, monitoring, and alerting. Field sanitarians in Ecolab’s Kay Division, which provides sanitation products and services to the food industry, foodservice, and grocery accounts, will install, service, and maintain the FreshLoc system.
The alliance can solve such problems as those faced by supermarkets, distributors, manufacturers, trucking companies, restaurants, and others in the food supply chain when their perishables are not maintained at proper temperatures, leading to spoilage or foodborne illness.
FreshLoc offers a number of advantages over other food temperature monitoring systems: wireless sensors allow flexibility to change facility layout; automatic alerting; accurate record keeping, providing complete and precise records of any or all monitored areas; labor savings, since employees don’t have to manually log temperatures and maintain records; versatility, since users can monitor information or print out reports as frequently or infrequently as they desire; and fast, easy installation without disrupting plant, store, warehouse, or truck operations.
FreshLook reports providing a snapshot of every area monitored are sent as e-mail and can be printed out, if desired, to provide data to submit to local health departments or analyze equipment performance. For example, the reports can be used to determine how cooling units on refrigerated trucks are performing and to identify which trucks can cool down fastest. They can also provide assurance to the retailer that the product was handled correctly, so it won’t be rejected.
One of the applications the system is being used in is a 500,000-sq-ft meat processing plant belonging to San Antonio–based HEB Inc., the largest grocer in Texas. It has been used for a number of purposes, ranging from identifying problems with the HVAC system to protecting against the growth of Escherichia coli, and has protected hundreds of thousands of dollars of inventory. In another application, Foster said, a restaurant complained that the food the distributor provided had been temperature abused, but the distributor presented documented data, obtained through use of the FreshLoc system, showing that it hadn’t been.
The alliance is beneficial to both companies, Foster said. Having both a chemical sanitation program and an electronic monitoring and alerting system is the ultimate in food safety. That puts an envelope around a brand and really protects it.
