Just as a new school year begins in many areas, some 8 tons of "Active Packs" kids' lunches have been recalled due to possible contamination with listeria bacteria.

No illnesses have been reported. Listeria can cause serious, sometimes fatal infections in young children, frail or elderly people, and people with weakened immune systems.

Tests conducted on behalf of Reichel Foods detected listeria in some of their products. The company has issued a recall for these products:

    5.6-oz packages of "Armour Active Packs Turkey & Cheese Wrap" Package Code 1026090112 or Case Code 27815-17994.
    5.6-oz packages of "Armour Active Packs Ham & Cheese Wrap" Package Code 1026090112 or Case Code 27815-17995.
    5.6-oz packages of "Armour Active Packs Cheese Pizza" Package Code 1026090112 or Case Code 27815-17996.
    2.75-oz single serve trays of Dippin' Stix Apples & Caramel with Peanuts. The affected case code dates are 09/01/12, 09/02/12, and 09/03/12. The affected single serve tray code dates are USE BY 01SEP2012, USE BY 02SEP2012, and USE BY 03SEP2012.

So far, only these specific items have been recalled. The pizza and Dippin' Stix products were added today to the initial recall issued on Sunday, Aug. 5.

The products were sent to distribution centers in Indiana, Minnesota, Pennsylvania, and Texas. From there they were sent to major retailers throughout the U.S.

Active Packs come in child-friendly boxed kits that contain wrap ingredients, sauce, and sliced apples with caramel dip.
