Reports of small chunks of blue plastic in Lean Cuisine brand frozen chicken dinners have led Nestle Prepared Foods Co. to recall 900,000 pounds worth of meals.

So far, the blue plastic has been found in three specific Lean Cuisine dinners -- Cafe Classics Pesto Chicken with Bow Tie Pasta, Spa Cuisine Chicken Mediterranean and Dinnertime Selects Chicken Tuscan. O'Hearn said the company has received seven consumer complaints, "with one report that a consumer bit into it."

According to the USDA, the contaminated dinners were produced between Aug. 18 and Oct. 27 of this year. To determine whether a dinner in your freezer is contaminated, O'Hearn said consumers can call 800-227-6188 to check the production codes on the side of Lean Cuisine packages.

The USDA has also provided a list of production codes so consumers can check to see if their dinners have been recalled. The following products are subject to recall:
