Highlights of the article:
What this means to us is that we must either throw away our PTFE coated pans, or make a promise to ourselves that we will not allow our pans to overheat. My recommendations include: 1) If you have a PTFE coated drip pan, throw it away, 2) Never boil water in a PTFE coated pan, 3) Never leave the kitchen when a PTFE coated pan is in use, 4) Cook at low or medium heat when using PTFE coated pans, 5) Use a culinary thermometer to determine the temperature at which your PTFE coated appliances (deep fryers, waffle makers) operate, 6)Never allow anyone to use PTFE coated cookware in your home unless instructed of its potential danger, 7) Ensure that your kitchen is properly ventilated, preferably by a hood that vents outdoors, and 8) If you are an absent-minded person: give your PTFE coated cookware away.

I would like to mention a few possible alternatives to PTFE toxicity when investigating sudden death associated with respiratory disease in pet birds. First, carbon monoxide is produced by combustion from fires, engines, and central heating units. It can be fatal, but causes postmortem findings different from PTFE fumes (e.g., bright red blood and pink or red tissues). Second, burned foods and cooking oil can emit toxic particles and fumes when cooked on any type of surface heated above about 260oC (500oF).5 Never put butter or oil in a pan heated on "high," and avoid using the "self clean" mode of your oven.7 Third, small amounts of natural gas in the air have caused death in birds. Never let the pilot light of your oven, stove, water heater, or dryer go out, and make sure your birds are in a well ventilated area away from sources of natural gas and propane. Finally, fluorocarbons and particulates from hair spray, perfume, spray deodorant, Pam7 cooking oil, spray starch, and other aerosols can also cause respiratory disease and death. Never use aerosol sprays in the same room as, or in close proximity to your birds.

It did however, cite several silicone coated products as relatively safe. However, if you investigate silicone further, you will discover some of the chemicals found in silicone which you may be familiar with, include: formaldehyde, polyvinyl chloride, urethane, acetone, freon, benzene, etc.
Ick! That's why I'm using stainless steel, cast iron, and glass pans myself.
