(nadia white) the moment a fish is pulled out from the water, it's a race against time. and keeping it in the right conditions is the best way to get that fish to your plate safely. (dane chauvel) sometimes the product arrives, and the cold chain has been interrupted, and we need to be able to identify where in the cold chain that occurred. (tom villa) we took our world class network, and we developed devices to track environmental conditions. this device allows people to understand what's happening with the location, but also if it's too hot, if it's too cold, if it's been dropped... it's completely unique. (dennis woloshuck) if you have a sensor that can keep track of your product, it keeps everybody kind of honest that way. who knew a tiny sensor could help keep the food chain safe? ♪
