Tyson Foods---the largest poultry processing company in the world, and a major packager of beef and pork products as well---pleaded not guilty yesterday to charges brought by the U.S. Justice Department that the corporation smuggled illegal immigrants into the country to work in company plants. Two company executives and four former managers have been fingerprinted and photographed by federal marshals in connection with the case, in which 36 in violations of immigration laws are alleged at 15 factories. Tyson officials have contested the accuracy of the indictment, which is the result of a three-year sting operation carried out by government agents.
