There have been concerns about the safety of Teflon when subjected to high heat in pressure cookers. When heated above 572°F (300°C), Teflon can release toxic fumes that are harmful to humans and pet birds. These fumes can cause a condition known as polymer fume fever, which is characterized by flu-like symptoms such as fever, chills, and headache.
However, it’s important to note that pressure cookers are designed to operate under high pressure and temperature. Most pressure cookers on the market today have safety features in place to prevent the release of these toxic fumes. The pressure and temperature inside the cooker are carefully controlled, ensuring that the Teflon coating does not reach the point of releasing harmful fumes.
Nevertheless, it is still advisable to follow the manufacturer’s instructions for using a pressure cooker and avoid exposing the Teflon coating to extreme temperatures. Proper care and maintenance of the pressure cooker, such as avoiding abrasive cleaning agents and using utensils that won’t scratch the surface, will help prolong the life of the Teflon coating and reduce the risk of any potential release of toxins.
In conclusion, when used correctly and with proper care, Teflon coatings in pressure cookers are considered safe. It’s essential to choose a pressure cooker with safety features and to follow the manufacturer’s guidelines to ensure a safe and enjoyable cooking experience.

Overview of Teflon Material
Teflon, also known as polytetrafluoroethylene (PTFE), is a synthetic fluoropolymer of tetrafluoroethylene. It is a nonstick material that is widely used in various applications, including cookware, due to its unique properties.
Teflon is known for its exceptional chemical resistance and high thermal stability. It has a very low coefficient of friction, which makes it a perfect choice for nonstick coatings in cookware like pressure cookers. The nonstick surface allows for easy food release, making cooking and cleaning effortless.
One of the key advantages of Teflon is its ability to withstand high temperatures. It has a melting point of around 620°F (327°C), which is well above the typical cooking temperatures used in pressure cookers. This means that Teflon-coated pressure cookers can safely handle the high heat and pressure without any adverse effects on the coating.
Teflon is also inert and nonreactive, meaning it does not react with most substances. This makes it safe for cooking acidic foods, such as tomatoes and vinegar, which can react with other materials. Additionally, Teflon does not release any harmful chemicals or toxins when heated, making it a safe choice for food preparation.
However, it is important to note that Teflon can release toxic fumes when it is heated above its recommended temperature, typically above 570°F (300°C). These fumes can be harmful to humans and pets if inhaled. Therefore, it is essential to use Teflon-coated cookware within the recommended temperature range and avoid overheating it.
