Concerns about the water supply in the area of Pilgrim's poultry processing plant in Guntersville, Ala., on the morning of Friday, October 11 forced the plant to shut down its first and second shift operations while crews worked to fix the issue.

Jack Swann, manager of the Guntersville Water Board, said Pilgrim's reported the issue at approximately 6 a.m. when workers noticed discoloration in the water system, which occurred after workers completed maintenance on some valves in another part of the city on October 10.

"It stirred up some debris that came off the metal pipeline," Swann said. "It looks like the iron caused some of the color to get in the water."

He said the water was tested and is safe to drink, and officials "just about have (the system) completely flushed out."
