"The settlement requires the potato chip producers to reduce acrylamide to 275 parts per billion in three years, a low enough level to avoid a Prop. 65 warning label. That amounts to a 20 percent reduction for Frito-Lay and an 87 percent reduction for Kettle Chips, Brown's office said. Little or no reduction will be needed for most Cape Cod chips, but one product, Cape Cod Robust Russets, will require a warning label, the attorney general said."

The acrylamide level of the potato increases as it browns. It appears the acrylamide level of these particular chips is therefore unavoidable.
