PORTLAND (AP) — Public health officials are warning consumers not to eat some Malt-O-Meal cereals after they were linked to salmonella.

The company is voluntarily recalling some packages of its unsweetened puffed rice and unsweetened puffed wheat cereals because they may be contaminated.

The cereal was sold nationally under the Malt-O-Meal brand and many private label brands. Affected brand names include Acme, America’s Choice, Food Club, Giant, Hannaford, Jewel, Laura Lynn, Pathmark, Shaw’s, ShopRite, Tops and Weis Quality. All of the recalled products are sold in plastic bags.

No cases of salmonella have been reported in Oregon.

Salmonella is a bacteria that can cause abdominal pain, nausea, vomiting and diarrhea. The infection can be most severe in the very young, the elderly and those with compromised immune systems.
