Each year about 1 in 6 people in the United States gets sick from eating contaminated food, according to the Centers for Disease Control (CDC). Salmonella is responsible for many of the reported outbreaks and causes more hospitalizations and deaths than any other type of germ found in food. While E. Coli infections have been drastically reduced, there has been no reduction in people getting sick from Salmonella.
One way to cut down on illness caused by Salmonella is to apply lessons learned from past outbreaks as depicted below.

Efforts to educate about prevention can be supplemented by enhancing the traceability of food shipments within the supply chain. The Food Safety Modernization Act calls for the FDA to focus on new food traceability rules to prevent contamination.
A report issued recenlty by ABI Research, “RFID-enabled Food Safety and Traceability Systems,” reviews the Food Safety Modernization Act and provides forecasts for the use of RFID-enabled devices in cold chain applications. RFID allows the food industry to trace food items and record environmental conditions throughout the entire supply chain.
Sensors in RFID tags monitor the temperature and humidity of products. They can detect if the temperature for a specific food item goes above or below the ideal temperature, at any given time, and record that detail. Tags can be used on anything in the supply chain from the farms, to slaughterhouses, to pallets, to shipping containers, to grocery stores. Even the cows and pigs can be tagged.
You may remember the Orange Juice recall from this past January. CNNMoney noted that if there is wide adoption of a traceability solution in the industry, it could stop the contaminated food from being put onto store shelves in the first place, and help stop outbreaks before they start.
Aside from preventing food borne illnesses, ABI Research also points out that the information delivered by an RFID traceability solution could have a significant impact on the $35 billion a year in wasted produce. With the environment detail captured by the RFID readers during the supply chain, a grocer or manufacturer can determine precisely which containers were exposed to temperatures outside of the ideal range, and discard only those containers instead of discarding the entire shipment.
The prevention of waste or food borne illness is enough to warrant an RFID food traceability mandate in my book. Being able to impact both? I’ll let you do the math.
