Generally, "such trace-back systems work in a way that's similar to how Federal Express tracks its packages. On the farm, animals and crop sections are given a 'smart' label with a unique number. The label is then attached to a bin, crate or container used for transport." Next, workers "can use a hand-held computer or smart phone to scan the labels and record key information, such as date and time, location, workplace temperature and which truck hauled the food away. The information is usually uploaded to a central online database, where it is stored and can be accessed via the Web." When the food is moved or handled by someone new, "the data can be updated and recorded."
Most of the farming community across the country has not adopted this technology, but proponents say it is "inevitable given public outrage over the recent scandal over contaminated eggs." Supporters of the technology say that it "could simplify the nation's highly complicated food-safety system, helping prevent or contain the harm caused by recalled food."
IBM Corp. and other technology companies are talking with state departments of agriculture and large growers associations about the tracing systems.
