A strain of bird flu has been found at a chicken farm in northeast Texas and the affected flock has been destroyed, Pilgrim’s Pride Corp. (NYSE:PPC - News), the No. 2 U.S. poultry producer, said on Friday. The Pittsburg, Texas-based company, whose shares were down 4 percent in early trading, said there was very little evidence of clinical signs of disease in the birds. It said that according to the Texas Animal Health Commission, this indicates the infection may be a low-level avian influenza.
