WASHINGTON – ConAgra Foods is recalling all Marie Callender's brand cheesy chicken and rice frozen meals after they have been possibly linked to a salmonella outbreak in 14 states.

The company said it was recalling the meals after it was informed by the federal Centers for Disease Control and Prevention of a possible link between the meals and 29 illnesses. Eight of those sickened reported eating the product in April or May 2010.

The Agriculture Department's Food Safety and Inspection Service, which announced the recall late Thursday, said the most recent illness was reported May 22.

The company is recalling all of the meals, which are labeled "Marie Callender's Cheesy Chicken and Rice White Meat Chicken and Broccoli over Rice Topped with Rich Cheddar Sauce," regardless of production date.

The product was distributed to retail outlets nationwide.

The most common symptoms of salmonella are diarrhea, abdominal cramps and fever within eight hours to 72 hours of eating a contaminated product. It can be life-threatening, especially to those with weakened immune systems.
