schools, burger chains ban targeted beef

The hamburger chains Jack-In-the-Box and In-N-Out as well more than 150 school districts around the nation have banned meat from a Chino slaughterhouse after a video showed workers brutalizing sick and crippled cows, officials said Friday.

The New York City public school system -- the nation's largest with 1.1 million students -- pulled all hamburgers from its menus.

School districts in at least 11 states have stopped using ground beef from Hallmark Meat Packing Co. and its associated Westland Meat Co. until a federal investigation is complete.
