What began as a small investigation into tainted milkshake powder has become a nationwide recall of related products.
No illnesses have been linked to the contamination of ingredients sold by a Minnesota milk cooperative. But the recalls, which are cascading through the food system, illustrate how just one tainted ingredient can affect dozens of companies.
Recalled products range from Malt-O-Meal's Maple & Brown Sugar Instant Oatmeal packets to Meijer hot chocolate mix to some Kroger popcorn toppings.
The U.S. Department of Agriculture first detected salmonella in a milkshake powder in June. The USDA and the FDA traced the contamination back to the Plainview Milk Products Cooperative.
