Cargill Inc [CARG.UL], one of the world’s largest privately held corporations, has launched a restructuring that includes job cuts, one company source and four industry sources said on Friday, the latest casualty of a downturn in the farm economy. The 150-year-old company, a top commodities trader, is also closing offices, two of the industry sources said. The cutbacks at the Minnesota-based company come as global agricultural companies are under pressure from slumping commodity prices, slowing demand in China and weakness in emerging markets where Cargill has significant investments.
