Nestle Purina is recalling 3.5 and 7 pound bags of Purina ONE Vibrant Maturity 7+ Dry Cat Food.
The cat food was produced over two days at a plant in Davenport, Iowa in 2010. Affected bags have a "best by" date of May 2012 and were shipped to 12 Midwest states.
Nestle-Purina says the Food and Drug Administration notified the company of the potential contamination.
