Black Pans: Scratches And Health Risks

Scratched black pots and pans can be dangerous to use. The black coating on non-stick pans is often made from polytetrafluoroethylene (PTFE), a chemical that is part of a group of chemicals known as PFAS (per- and polyfluoroalkyl substances). When a non-stick pan is scratched, small particles of PTFE can flake off into your food, and a single scratch on a non-stick pan can release millions of toxic micro-plastic particles. These particles are known as forever chemicals because they take so long to break down.

The potential health impacts of PFAS come from exposure that builds up over time, and these chemicals have been linked to various health issues, including liver issues, high blood pressure, and some cancers in humans.

Scratches can cause flakes of toxic chemicals to end up in your food

Scratches on black pots and pans can cause flakes of toxic chemicals to end up in your food. The non-stick coating on these pans is often made with PFAS (per- and polyfluoroalkyl substances), which are known as "forever chemicals" due to their longevity. One common PFAS is polytetrafluoroethylene (PTFE), found in the popular brand name Teflon.

When a non-stick pan made with PFAS is scratched, small particles can flake off into your food. A 2022 study found that a single scratch on a non-stick pan can release up to 2.3 million microplastics and nanoplastics. These particles can have toxic effects on the body, and have been linked to various health issues, including liver issues, high blood pressure, and some cancers in humans.

To avoid exposure to these potentially harmful chemicals, it is recommended to replace any non-stick cookware when the coating is damaged, especially if it was manufactured before 2015. It is also advised to use soft utensils made of wood or silicone when cooking with non-stick pans to avoid scratching the surface.

Overheating nonstick pans can release toxic fumes

Overheating Non-Stick Pans Can Release Toxic Fumes

Non-stick pans are coated with a material called polytetrafluoroethylene (PTFE), also known as Teflon. Teflon is a synthetic chemical made up of carbon and fluorine atoms. While Teflon is considered safe for everyday home cooking, at temperatures above 500°F (260°C), Teflon coatings on non-stick cookware start to break down, releasing toxic chemicals into the air.

Inhaling these fumes may lead to polymer fume fever, also known as the Teflon flu, which consists of temporary, flu-like symptoms such as chills, fever, headache, and body aches. The onset occurs after 4-10 hours of exposure, and the condition usually resolves within 12-48 hours. However, a small number of case studies have also reported more serious side effects of exposure to overheated Teflon, including lung damage.

To minimize the risk of releasing toxic fumes from your non-stick pans, follow these tips:

• Don't preheat an empty pan. Always have some food or liquid in pots and pans before preheating.
• Avoid cooking on high heat. Cook on medium or low heat and avoid broiling, as this requires temperatures above those recommended for non-stick cookware.
• Ventilate your kitchen by turning on the exhaust fan or opening windows to help clear any fumes.
• Use wooden, silicone, or plastic utensils to avoid scratching the non-stick surface and reducing the life of your cookware.
• Hand wash gently with a sponge and warm, soapy water. Avoid using steel wool or scouring pads, as they can scratch the surface.
• Replace old cookware. When Teflon coatings start to visibly deteriorate with excessive scratches, peeling, flaking, or chipping, it's time to replace them.

Nonstick pans are harder to clean and more prone to scratching

Non-stick pans are notoriously difficult to keep in pristine condition. Even if you're careful, over time, non-stick pans are prone to scratching, and once the surface is compromised, it's easier for food to stick to the pan, and toxins may leach into your food.

To keep your non-stick pans in good condition, it's recommended that you hand-wash them with a soft sponge, and avoid using metal utensils. Instead, opt for wooden or silicone cooking utensils to prevent scratching the surface. When storing your non-stick pans, it's a good idea to place a cloth towel over the surface to prevent scratches from pans being stacked on top of each other.

Despite your best efforts, your non-stick pans will likely become scratched over time, and this is when they can become unsafe to use. A scratched non-stick pan can release millions of toxic micro-plastic particles into your food, and the risk is higher if the pan is heated above 500°F. These toxic particles can be harmful to humans, and have been linked to various health issues, including liver issues, high blood pressure, and certain cancers.

Therefore, it's important to replace your non-stick pans regularly, especially if the coating is scratched or starts to degrade. It's recommended that you replace non-stick pans every three to five years, or as soon as you notice any scratches or damage to the surface.

Scratches can cause flakes of perfluorooctanoic acid, linked to tumours and toxic effects on the immune, liver and endocrine systems

Scratches on black pots and pans can cause flakes of perfluorooctanoic acid (PFOA) to be released into your food. PFOA is a synthetic chemical compound that has been used in various industrial processes since the 1940s. It is commonly found in non-stick cookware, such as Teflon, as well as in carpeting, upholstery, apparel, floor wax, textiles, firefighting foam, and sealants.

PFOA has been linked to a range of toxic effects on the human body, including:

• Tumours: The International Agency for Research on Cancer (IARC) has classified PFOA as carcinogenic to humans, with studies showing that it can cause cancerous tumours in the liver, pancreas, and testicles of lab animals.
• Immune system: PFOA can act as an immune system toxicant, affecting the function of immune cells and increasing the risk of infections and autoimmune diseases.
• Liver: In addition to liver tumours, PFOA can cause developmental and reproductive toxic effects on the liver in test animals. It is primarily stored in the liver and can affect liver function.
• Endocrine system: PFOA is considered an endocrine-disrupting chemical, which can interfere with hormone production and function. It has been linked to altered thyroid hormone levels and increased cholesterol levels in humans.

It's important to note that while scratches on non-stick cookware may release PFOA, the health risks are generally considered lower if the pan is used at recommended low-heat temperatures. Additionally, newer non-stick coatings have been developed that do not contain PFOA, although their long-term health effects are still being studied. To minimize exposure to PFOA and other potential toxins, it is recommended to use alternative types of cookware, such as cast iron or stainless steel, and to properly care for and regularly replace non-stick pans.

Scratches can expose you to chromium and nickel, which can cause health issues like dermatitis

Scratches on black pots and pans can expose you to chromium and nickel, which may cause health issues like dermatitis. This is especially true for those with nickel sensitivity.

Dermatitis, also known as eczema, is a condition that causes the skin to become inflamed, itchy, and red. It is often caused by an allergic reaction to certain substances, such as nickel. When cookware is scratched, tiny flakes of the coating can end up in your food, and if ingested, nickel and chromium can cause an allergic reaction in the body, leading to dermatitis.

The risk of exposure to these metals depends on several factors, including the grade of stainless steel used in the cookware, the cooking time, and the previous usage of the cookware. For example, cooking with new stainless steel or for longer durations may result in higher amounts of nickel and chromium leaching into food. Additionally, certain types of foods, such as acidic foods like tomato sauce, can increase the amount of metal leaching.

To minimize the risk of exposure to these metals, it is recommended to avoid using scratched cookware and to opt for alternative materials such as cast iron, carbon steel, or ceramic. It is also important to properly care for your cookware by avoiding metal utensils and harsh cleaning methods that can cause scratches.

While the potential health risks of scratched black pots and pans are a concern, it is important to note that the impact of exposure to chromium and nickel may vary depending on individual sensitivity and the amount ingested. Some people may experience no issues, while others may develop dermatitis or other allergic reactions.
