Because birds have extremely sensitive respiratory systems, bird owners must take precautions to protect them. Cooking fumes, smoke and odors that have little or no effect on people can seriously sicken and even kill birds, often quite quickly. Cooking fumes from any type of unattended or overheated cookware, not just non-stick, can damage a bird’s lungs with alarming speed. This is why bird owners should take steps to protect their pets, such as keeping their birds out of the kitchen, never leaving cookware unattended, never allowing pots and pans to overheat, and making sure that their kitchen is properly ventilated at all times.

In terms of Polymer Fume Fever… Over the past 40 years, there have been only a few reported accounts of polymer fume fever as a result of severely overheating non-stick cookware. It should be noted that butter, fats, and cooking oils will begin to smoke at approximately 400°F (204°C), producing fumes that can irritate eyes, nose, and throat and possibly cause respiratory distress. DuPont non-stick coatings will not begin to deteriorate in appearance or performance until the temperature of the cookware reaches about 500°F

Regulatory agencies, consumer groups and health associations all have taken a close look at the Teflon® brand. This article highlights what they found — the bottom line is that you can use Teflon® non-stick without worry.
