Non-stick cookware has become an inseparable part of every kitchen. It has gained popularity because it requires a very small amount of oil for cooking and is easy to clean and handle. Cooks who are inclined towards low-fat cooking, use it more than anyone else. Since 1960, non-stick pots and pans are being used without any concern, but now, several experts have raised issues over non-stick cookware safety. However, the United Sates Environmental Protection Agency (EPA) has not yet made any recommendations regarding their usage.
Safety Concerns for Non-stick Cookware
The major concern is the presence of chemicals belonging to the family, perfluorooctanoic acid (PFOA). This chemical, that is used to bind the non-stick layer to the cookware, is associated with environmental concerns. PFOA is not a naturally occurring chemical in the environment, but is found to be persistently present. Studies have revealed the presence of minute quantities of this chemical in the blood of major chunk of the American population. Tests with laboratory animals infer that, this chemical is carcinogenic and leads to developmental and other adverse effects like low birth weight and reduced immunity. Effects of low doses of PFOA on human beings are disputed, but its effects on animals definitely raises a concern for human safety.
The presence of PFOA is observed in 9 out of 10 Americans, but the means of its transmission to human beings is not known. Non-stick cookware can be one of the reasons, but this cannot be said for sure. The reason, as to why this cookware is considered as one of the ways of transmission of PFOA to the human body, is related to high cooking temperatures. It is considered that, at extremely high temperatures, the non-stick layer on the cookware breaks down and releases toxic fumes which can be harmful, if inhaled. Non-stick cookware can easily attain high temperatures if left dry or empty on a high flame. Manufacturers have recommended cooks to use temperatures less than 500°F. They also say that, temperatures above 660°F will cause significant decomposition of the non-stick layer resulting in release of toxic fumes. According to the Environmental Working Group (EWG), toxic gases released at temperatures as low as 464°F are known to kill birds. But if cooking temperatures are maintained within the set limit, there is no harm in using non-stick cookware as the plating remains intact.
- Use of metal utensils on non-stick vessels must be avoided.
- Cooking temperatures must be maintained below 450°F to prevent decomposition of the non-stick plating.
To be on the safer side, cooks can resort to cookware made up of other inert materials to ward off the risk associated with non-stick cookware. Some of the safest replacements are mentioned below.
Considering safety concerns, the EPA has asked many companies to find alternatives for PFOA so that, its usage for making cookware can be completely avoided. The EPA has also mentioned that people using non-stick cookware can continue using it, as there is little to worry about. If used properly, safety issues will not arise with this cookware. The above discussion clearly brings out that, good quality non-stick cookware is safe to use, only when it is used in the right way.
