U.S. Trade Representative Carla Hills signed a trade accord Friday with Japan that is expected to boost exports of U.S. farm products, particularly corn.

"Over the next three years, we expect that the package of concessions we have just won from Japan will add an estimated $75 million to $95 million in extra sales for U.S. farmers," said Agriculture Secretary Edward Madigan.Madigan said the lion's share of the new growth would go to U.S. corn producers but that significant gains are also expected for various processed dairy products such as whey, a byproduct of cheese production; dairy-based bakery goods, such as cheese-stuffed pasta; ice cream mixes; cheese food; and dietary supplements.
