There is some debate about whether Teflon coating is harmful to health. Teflon is a brand name for a type of non-stick coating called polytetrafluoroethylene (PTFE), which is used in many cookware and kitchen appliances, including rice cookers. While the U.S. Environmental Protection Agency (EPA) has stated that PTFE is not harmful to health when used properly, there are some potential concerns that have been raised.

Or is Teflon coating bad for health?

One concern is that when Teflon is heated to high temperatures (above 570°F/300°C), it can release toxic fumes. These fumes can cause a condition known as polymer fume fever, which can cause flu-like symptoms such as fever, chills, and headache. However, it is important to note that it is very rare for a rice cooker to reach such high temperatures, so the risk of this occurring during normal use is low.

Another concern is that when Teflon is scratched or damaged, small particles of the coating can be released into the food being cooked. Ingesting these particles has been linked to potential health problems, including an increased risk of cancer and other health issues. However, this risk can be minimized by using the rice cooker according to the manufacturer’s instructions and avoiding the use of metal utensils that could scratch the coating.

In general, Teflon-coated rice cookers and other kitchen appliances are considered safe for use as long as they are used according to the manufacturer’s instructions and are not subjected to extremely high temperatures. However, if you are concerned about the potential risks of Teflon, there are alternative materials you can choose, such as ceramic or stainless steel, which do not have the same potential health concerns.
