Castleberry's Food Co. expanded its recall of canned meat on Saturday to more than 80 types of canned chili, beef stew, corned beef hash and other meat products in addition to the 10 brands it had recalled Thursday due t o fear of a botulism outbreak
The meat processor said cans of chili sauce made at the Castleberry's plant were found in the homes of an Indiana couple and two children in Texas who had been hospitalized with botulism. All four are expected to survive.

The Agriculture Department's Food Safety and Inspection Service said Thursday that an equipment malfunction may have been responsible for the contamination.

On Saturday, FSIS said the malfunctions at the Augusta, Georgia, processing plant may have existed longer than initially estimated.

"We believe we have isolated the issue to a situation of under-processing on one line of our production facility," said Senior Vice President Steve Mavity. "As an extra precaution to the recall we announced on Wednesday, we have shut down this line altogether and are recalling all products produced on it."

Brand names of the recalled products include Austex, Best Yet, Big Y, Black Rock, Bloom, Bryan, Bunker Hill, Castleberry??s, Cattle Drive, Firefighters, Food Club, Food Lion, Goldstar, Great Value, Kroger, Lowes, Meijer, Morton House, Paramount, Piggly Wiggly, Prudence, Southern Home, Steak N Shake, Thrifty Maid, Triple Bar and Value Time. The recall also includes four varieties of Natural Balance dog food.

Botulism is a muscle-paralyzing disease caused by a toxin made by a bacterium, Clostridium botulinum. Such bacteria are commonly found in soil.
