IBM has set out to prove it can revolutionize the food industry with data, starting with China. Six industrial slaughterhouses and 100 markets in Shandong Province are part of a large scale test in tracking pork from farm to customer. Pigs are marked with ear tags containing unique barcodes, those same barcodes appear on the bins that carry their meat during processing, and on the packages for the pork placed in stores. In the near term, IBM hopes that knowing the history of every piece of meat will enable fast and super accurate recalls in case of contamination. Eventually, this kind of comprehensive tracking could help farmers keep pigs healthier, improve the quality of meat after it is cut, and even place a picture on the store package of the exact pig made into that pork product. Knowledge is power in this new take on the supply chain.
