Nestlé says thieves have stolen a huge shipment of KitKat bars from a truck heading from Italy to Poland. On Friday, the company said the vehicle and its cargo still have not been found. The bars disappeared last week while moving between production and distribution sites. Nestlé says the load totals about 12 tons, or more than 400,000 bars. The company says the bars were meant for sale across Europe. Nestlé warns they could show up in unofficial markets. It says each bar has a batch code. Shoppers and retailers can scan codes and report matches.
