Malt-O-Meal voluntarily recalled its unsweetened Puffed Rice and Puffed Wheat cereals on April 5 after finding salmonella contamination during routine testing. The affected bags were produced in the past 12 months in Northfield.

Symptoms of salmonella infection include nausea, vomiting, fever, diarrhea and abdominal cramps. It can be life-threatening for people with poor health or weakened immune systems, including young children and the elderly.

Consumers with products from the recalled lots are advised to throw them out.

(The FDA said the recalled products were distributed nationally under the Malt-O-Meal brand name, as well as private labels including Acme, America's Choice, Food Club, Giant, Hannaford, Jewel, Laura Lynn, Pathmark, Shaw's, ShopRite, Tops and Weis Quality. The cereal bags have "best if used by" dates from April 8, 2008 (coded as APR0808), through March 18, 2009 (coded as MAR1809).
