Nordicware's FAQ web page states: PTFE (an entirely different compound than PFOA) is the material that gives nonstick surfaces their “slipperiness” and is widely used in consumer cookware coatings, including many of Nordic Ware’s stovetop cookware products.
Since they do not deny that they are using that particular surfactant, I read their statement that they still use it and since PTFE and PFOA are compounds proven to be dangerous to birds, I think you have your answer, however, you could either E-mail them or send them a letter via regular mail, asking them specifically if a particular product contains either a PTFE or PFOA coating of any kind.....
There are numerous stainless steel bakeware, by various manufacturers, that are free of PTFE or PFOA coatings.....you can also easily find aluminum products without any of these coatings.....
