DES MOINES, Iowa (AP) — Pinnacle Foods Group is recalling nearly 91,000 pounds of bourbon barbecue sausage products made at its plant in Fort Madison because they may have been undercooked. The U.S. Department of Agriculture says the company discovered the problem, which it believes was caused by processing time miscalculations. There have been no reports of illnesses.

The product is 5-ounce cans of “Armour Vienna Sausage Bourbon BBQ Flavored.” The cans have an establishment number P-4247 inside the USDA inspection mark. The products were produced on Sept. 7, 2012.

Pinnacle Foods Group is headquartered in Mountain Lakes, N.J., and has over 4,500 workers in 21 sites in North America.
