I believe it is not a simple issue of labelling Gore-Tex & other high tech materials as dangerous and avoiding their use completely. Rather, consider what Harvey Glick, Director for Scientific Affairs at Monsanto, a company working on biotechnology in agriculture has in mind when posed with such a problem has to say:
"The real risk to society is to not develop technology that can deliver real benefits to society. It's important to understand the magnitude of risk and then marry that with the societal benefits that may accrue."
"But the truth is that these questions don't really have hard-and-fast answers, Rodemeyer says. We assume there's a scientific answer and there isn't. "What level of risk is acceptable is ultimately a policy question, and yet we keep asking our scientists to answer it — and they can't."
