That, at least, is the conclusion of a pair of institutional shareholders in Berkshire Hathaway, who believe more food and consumer deals may be on Buffett's plate, along with possible acquisitions of companies outside the U.S. "I wouldn't be surprised, personally, to see more food industry acquisitions, in part because there are scale advantages, in part because there's an enormous amount of wasted effort amongst companies in the industry," said Tom Russo, partner at money manager Gardner Russo & Gardner in Lancaster, Pa. Berkshire recently struck a deal with Brazilian private equity firm 3G to buy Kraft Foods for $40 billion and merge it with Heinz, which Berkshire and 3G bought together in 2013.
