In its update today on the investigation into the ongoing Salmonella outbreak, the U.S. Drug Administration acknowledged:

In many instances, the peanut butter and peanut paste manufactured by PCA (the Georgia plant implicated in the outbreak) are further distributed to manufacturers to be used as ingredients in many products, including cookies, crackers, cereal, candy and ice cream.

What does this mean?

According to the AP, is that the FDA is expanding its investigation of peanut products in a Salmonella outbreak that has sickened hundreds and killed at least six.  In addition, the FDA is notifying 30 to 85 companies that bought peanut butter or peanut paste from a Georgia facility to test their products and asked to consider halting sales.  A list of companies that may be using the contaminated peanut butter has yet to appear on FDA website.
