Arkansas-based Pinnacle Foods Group, LLC has issued a recall for approximately 668,316 pounds of poultry products due to misbranding because the product contains monosodium glutamate (MSG), which is not declared on the label, according to USDA’s Food Safety and Inspection Service (FSIS).

The products, poultry dinner items, were produced between December 11, 2013 through June 9, 2015. The following products are subject to recall: 383 g frozen dinners of “Swanson Stuffing Baked Turkey.”

Products were shipped to retail locations in Canada.

FSIS says the problem was discovered during routine in-plant verification activities.

 FSIS and the company have received no reports of adverse reactions due to consumption of these products.
