Consuming small, isolated flecks or particles of non-stick pan coating that have come loose is generally considered low risk. Most non-stick coatings, including Teflon, are made from polytetrafluoroethylene (PTFE), which is chemically inert and passes through the digestive system without being absorbed. Ingesting a small amount of non-stick coating is unlikely to cause immediate harm or toxic effects.
However, it is important to note that intentionally or repeatedly ingesting non-stick coating is not recommended. Although PTFE is generally considered safe at normal cooking temperatures, it can release potentially harmful fumes when overheated at temperatures above 500°F (260°C). This can occur if a non-stick pan is left empty on high heat or if the pan is heated above its recommended temperature limit.
If you accidentally consume a small amount of non-stick coating, it is unlikely to cause significant health problems. However, if you experience any adverse symptoms, such as stomach discomfort, nausea, or vomiting, it is advisable to seek medical attention.
To prevent the risk of ingesting non-stick coating, it's essential to maintain your cookware properly. Avoid using utensils or abrasive cleaning tools that can scratch the non-stick surface, as it may cause the coating to come loose. Regularly inspect your cookware for signs of wear and tear, and replace it if the coating is extensively damaged or flaking off.
