WASHINGTON D.C. (WTVB) - Food banks and farmers should be benefiting from a huge federal meat buy.  The Department of Agriculture program will purchase as much as 170-million dollars worth of chicken, pork, lamb and catfish in an effort to help the nation's food producers as drought scorches the country.  The products will be funneled to food assistance programs.  Another part of the program will involve the Department of Defense.  Defense will "encourage" its suppliers to buy meats and fish now and freeze the products for use later.  A White House official calls the move a "win-win," noting that farmers can sell more of their goods, with taxpayers getting a better price now than if buying later.
