Recalls push more companies to adopt digital tools that can prevent or contain the harm caused by contaminated food.

Reporting from San Jose — Inside a Silicon Valley company’s windowless vault, massive servers silently monitor millions of heads of lettuce, from the time they are plucked from the dirt to the moment the bagged salad is scanned at the grocery checkout counter.
That trail can be traced in seconds, thanks to tiny high-tech labels, software programs and hand-held hardware gear. Such tools make it easier for farmers to locate possible problems — a leaky fertilizer bin, an unexpected pathogen in the water, unwashed hands on a factory floor — and more quickly halt the spread of contaminated food.
This Dole Food Co. project and similar efforts being launched across the country represent a fundamental shift in the way that food is tracked from field to table. The change is slow but steady as a number of industry leaders and smaller players adopt these tools.
