As long as you don't overheat the teflon pans, there is no problem with PFOE. This chemical has not been used for the manufacturing of cookware teflon since 2013, but this doesn't mean that the replacements are totally safe. Simply put, don't use the pans for things like blackening fish, where you would preheat a CI pan for several minutes, as this could break down the PTFE, and cause smoking. But it will take a very high temp. Even the teflon flaking off old pans wasn't really a problem, as it is inert, though it's still a good idea to replace things like that!
