Is Teflon Cookware Safe? A Comprehensive Guide to Nonstick Pans and Your Health

teflon/clicxpost

When I purchased my first set of pots and pans, I opted for Teflon-coated cookware. At the time, Teflon was the gold standard for nonstick surfaces, promising effortless cooking and easy cleanup. For years, my husband and I enjoyed the convenience of our Teflon pans, but as reports about its potential dangers surfaced in the early 2010s, I decided to replace them with stainless steel, cast iron, and ceramic-coated alternatives.

However, Teflon cookware eventually found its way back into my kitchen. Its affordability and ease of use were hard to resist, especially with a busy household of four children. But as my new Teflon pans began showing signs of wear, I couldn’t help but worry about the potential health risks. My husband, on the other hand, believes my concerns are overblown and insists that modern Teflon is safe. To settle the debate, I turned to experts for clarity.


What Is Teflon Cookware, and How Can You Identify It?

Teflon is a brand name for polytetrafluoroethylene (PTFE), a synthetic material known for its nonstick properties. It’s widely used in cookware because it allows food to slide off effortlessly, reducing the need for excessive oil or butter. But how do you know if your cookware contains Teflon?

  1. Check the Label or Packaging:
    Look for terms like “Teflon” or “PTFE” on the product label or packaging. These indicate the presence of a Teflon coating.
  2. Inspect the Cookware:
    If the packaging is long gone, examine the cookware itself. Teflon-coated pans typically have a smooth, shiny, dark surface. Some manufacturers also stamp the Teflon logo on the bottom of the pan.
  3. Research the Brand:
    If you’re unsure, a quick online search of the cookware brand or model can confirm whether it uses Teflon.

The Evolution of Teflon: What’s Changed Over the Years?

Teflon has undergone significant changes since its introduction. The primary concern with older Teflon cookware was its use of perfluorooctanoic acid (PFOA), a chemical used in the manufacturing process. PFOA belongs to a group of chemicals known as per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals” due to their persistence in the environment and the human body.

Health Risks Associated with PFOA:

  • Developmental Delays: Exposure to PFOA has been linked to developmental issues in children.
  • Hormonal Imbalances: PFAS can disrupt endocrine function, affecting hormone regulation.
  • Increased Cancer Risk: Long-term exposure to PFOA has been associated with certain types of cancer.
  • Reduced Fertility: Studies suggest that PFAS may impact reproductive health.

In 2013, manufacturers phased out the use of PFOA in Teflon production, replacing it with short-chain PFAS, which are believed to be less harmful and break down more quickly in the body. According to experts like David Nadler, a research assistant professor at the New York Institute of Technology, modern Teflon cookware is now produced using safer manufacturing processes.


Is Modern Teflon Cookware Safe?

The short answer is yes—when used correctly. Modern Teflon cookware made without PFOA poses minimal health risks if properly maintained. However, there are still some precautions to keep in mind:

  1. Avoid High Heat:
    Heating Teflon cookware to temperatures above 500°F (260°C) can cause the coating to break down, releasing toxic fumes. This condition, known as “Teflon flu,” can cause flu-like symptoms in humans and is potentially fatal to pet birds. To minimize risks, cook on low to medium heat and avoid preheating empty pans.
  2. Inspect for Damage:
    Scratched or chipped Teflon coatings can flake off into your food, posing a ingestion risk. Replace cookware that shows visible signs of wear, as damaged coatings are less effective and potentially hazardous.
  3. Use Proper Utensils:
    Avoid metal utensils that can scratch the nonstick surface. Opt for silicone, wood, or plastic tools to preserve the coating.
  4. Gentle Cleaning:
    Clean Teflon cookware with soft sponges and mild detergents. Avoid abrasive scrubbers or harsh chemicals that can damage the coating.

How Does Teflon Compare to Other Cookware Options?

While Teflon remains a popular choice for its affordability and convenience, it’s worth considering how it stacks up against other types of cookware:

  • Stainless Steel: Durable and versatile, but requires more oil to prevent sticking.
  • Cast Iron: Excellent heat retention and naturally nonstick when seasoned, but heavy and high-maintenance.
  • Ceramic-Coated: Nonstick and free of PFAS, but may not be as durable as Teflon.

Ultimately, the best cookware for you depends on your cooking habits, budget, and health concerns.


Practical Tips for Safe Teflon Use

To enjoy the benefits of Teflon cookware while minimizing risks, follow these expert-recommended tips:

  1. Replace Old Cookware:
    If your Teflon pans were manufactured before 2013, it’s time to upgrade. Modern Teflon is safer and free of PFOA.
  2. Monitor Cooking Temperatures:
    Use a kitchen thermometer to ensure you’re not overheating your pans. Stick to low or medium heat settings.
  3. Store Carefully:
    Avoid stacking Teflon pans, as this can cause scratches. Use protective liners or pan protectors if stacking is unavoidable.
  4. Dispose Responsibly:
    When it’s time to replace your Teflon cookware, check local recycling guidelines. Some facilities accept nonstick pans for proper disposal.

The Bigger Picture: Teflon and Environmental Impact

While modern Teflon cookware is safer for consumers, the production and disposal of PFAS-based materials still pose environmental challenges. PFAS chemicals are persistent pollutants that can contaminate water sources and ecosystems. As consumers, we can advocate for stricter regulations and support brands that prioritize sustainable manufacturing practices.


Final Thoughts: Balancing Convenience and Safety

Teflon cookware offers undeniable convenience, but it’s essential to use it responsibly to protect your health and the environment. By following proper care guidelines and staying informed about the latest research, you can enjoy the benefits of nonstick cooking without unnecessary risks. For those with lingering concerns, exploring alternatives like ceramic-coated or cast iron cookware may provide peace of mind.

Heatwaves scorch England’s apples, starve cattle and cut grain yields

By George Mensah 5 min read

England’s summer heatwaves are pushing fruit growers, cattle farmers and grain producers into a season of shrinking harvests, spoiled crops and tough financial choices, with growers in Kent, Surrey and West Horsley all reporting damage that in some cases has cut yields by nearly half.

At Amsbury Farm near Maidstone, Kent, Clive Baxter manages roughly 200 acres (81 hectares) of fruit trees. He says the repeated spells of extreme heat this summer have hit nearly every part of his operation. “Everything is suffering now in the heatwaves,” Baxter said.

Bramley apples, a variety long associated with English cooking, are proving especially vulnerable. “Bramley apples are very susceptible to sunburn so we are spraying them with a clay substance that acts like suncream,” Baxter said. He explained that traditional English varieties, including Bramleys and Coxes, were never bred to withstand the kind of sustained heat the region has experienced this year.

The damage becomes severe once temperatures climb past a certain threshold. “Once the temperature gets to 30 degrees and above, if there is no wind, the juice starts to boil in the apples and cooks the fruit,” Baxter said. “When this happens it means the fruit is of no value at all.”

To protect what remains of the crop, Baxter’s team has started thinning the trees, deliberately removing some fruit so the rest has a better chance of surviving. He said the trees themselves are showing signs of strain. “So stressed” is how he described them, adding that the practice, while necessary, means lower yields and smaller apples overall.

Cattle farmers run out of grass

The heat is creating a different kind of pressure eighty miles away in Brockham, Surrey, where Nellie Budd raises 247 cows. For Budd, the central problem this summer has been simple: there is not enough food for the herd to eat.

“We have had 47 days now with no rain,” Budd said. “Grass normally is so resilient, once we cut it for hay or cut it for silage it will come back and we can continue grazing, but, this year, with the heat, there has been no let up.”

With pasture failing to regrow, Budd has started feeding her cattle hay that was meant to carry them through winter, a move that leaves her with a shortfall she will need to make up before the cold months arrive. The shortage is already changing the size of the animals she can bring to market.

“With limited food to eat, the carcasses are just not getting big enough which means they are not going to be the size for what we want because they are beef cattle,” Budd said.

Cutting the size of her herd is not something she is willing to consider, even as costs rise. “We have been putting an overlay in our grasslands to try and help but, this year, with no moisture in the ground, we couldn’t do anything,” she said. Reducing cattle numbers, she added, is not an option, because her family “could not afford to live” if she scaled back.

Budd said she is left hoping conditions change before next year’s growing season begins. “Everything is a gamble for farmers and we just hope weather patterns cause a wetter year next year,” she said.

Grain yields down by a third or more

Further west, at Woolgars Farm in West Horsley, arable farmer and contractor Peter Knight is currently harvesting around 2,000 acres (809 hectares), and the numbers coming in are worse than he expected. He traces the trouble back to the first heatwave in May, which struck right as his spring barley, a crop used mainly for brewing beer, needed steady moisture to establish itself.

“Spring barley, which is used for making beer, is planted in March and it has had very little rain on it since then,” Knight said. The timing compounded the damage. “The crops flower in early June but, at that time the heat puts it under stress, which means we immediately know the yield is going to be impacted,” he said.

Knight said the dry spell never really let up through the grain-filling period, the weeks when kernels normally bulk up in size and weight. Without rain during that window, the plants simply could not put on the growth needed for a strong harvest.

He is now watching a pattern repeat itself. “We are very worried because three out of the last five years we have had very similar weather patterns in terms of drought-like conditions and trying to manage our way through that is very difficult,” Knight said.

Unlike some fruit and vegetable operations, arable farms of this scale have few tools to fight back against drought. Knight said irrigating thousands of acres of grain is not realistic given the cost and infrastructure it would require. Instead, he has adjusted his methods where he can. “We are doing our best by trying to sow earlier in the spring and we are doing less cultivations which helps preserve moisture but this year the yield here is reduced by around 30-40% on what we would normally expect,” he said.

Knight said the consequences extend beyond his own farm. If the current weather pattern continues to disrupt arable output across the country, he expects Britain will need to lean more heavily on imported grain to make up the difference.

A season of adjustments across the industry

Baxter’s spraying regimen, Budd’s early dip into winter feed stores, and Knight’s earlier sowing and reduced cultivation all point to the same reality: farmers across different sectors are making real-time changes to how they operate, not waiting for the season to end before responding.

None of the three describe the heat as a one-off. Knight’s reference to three drought-affected years out of the last five suggests a pattern rather than an isolated bad summer, and Budd’s decision to protect her herd size despite the financial strain signals she expects to need that stock again once conditions improve.

For now, the fruit that survives will carry a higher cost of production, the cattle coming to market will run smaller than usual, and the grain harvest at Woolgars Farm will fall well short of a typical year. Whether next year brings the wetter conditions farmers are hoping for remains the open question hanging over the rest of the 2026 growing season.

Vozinha’s world cup heroics earn him a sea slug named in his honour

By George Mensah 4 min read

Cape Verde goalkeeper Vozinha has picked up an unexpected honour after his run at the World Cup, with scientists naming a newly identified sea slug species after him.

The Cape Verde islanders pushed Argentina to extra time before falling 3-2, a result that capped a tournament run few had predicted for the small West African nation. Before that exit, Vozinha kept a clean sheet in a goalless draw against European champions Spain, a result that gave Cape Verde its first-ever point at a World Cup.

That performance changed his profile almost overnight. His Instagram following jumped from 50,000 to 17.4 million, a number that puts him ahead of NFL veteran Tom Brady in social media reach.

A New Species Named In His Honour

Biologist Jesus Ortea, a professor emeritus at the University of Oviedo, found the small red mollusc in the Caribbean and gave it the name Aldisa vozinha, tying it directly to the 40-year-old goalkeeper.

In his published report on the discovery, Ortea wrote that he wanted to mark Vozinha’s role at the tournament. He also pointed out a detail that made the choice feel deliberate rather than arbitrary: the slug’s red colouring mirrors the nickname of Spain’s national team, La Roja, the side against whom Vozinha delivered his best-remembered display.

“The red colour of the dedicated species is a reminder of his feat,” Ortea wrote.

A Scientist With A Football Habit

This isn’t the first time Ortea has mixed marine biology with football. At 75, he has built a pattern of naming new species after players who catch his attention during major tournaments.

He previously named a species discovered in Costa Rica after Keylor Navas, the goalkeeper who played for Costa Rica at several World Cups and spent time at Real Madrid, Paris Saint-Germain and Nottingham Forest.

Ortea also named a separate creature after Quini, the former Sporting Gijon striker, picking a species whose colours matched the club’s kit.

His connection to Cape Verde goes beyond this latest naming. Ortea received the country’s Medal of Merit in 2023 for his research in the waters surrounding the island nation, work that had already put him in contact with Cape Verdean officials before Vozinha’s World Cup run began.

A Breakthrough Run For Cape Verde

Cape Verde’s World Cup campaign stood out as one of the tournament’s more unexpected stories. A nation of roughly 500,000 people reached a stage most had not anticipated, and Vozinha’s saves against Spain became the moment that defined the run for many watching outside the country.

The draw with Spain secured a point that Cape Verde had never managed at a World Cup before that match. Reaching the knockout stage and taking Argentina to extra time added to a run that turned Vozinha into one of the tournament’s more recognisable figures, despite representing one of its smaller footballing nations.

His social media numbers reflect how quickly that recognition spread. Going from 50,000 followers to 17.4 million in the span of a single tournament put him among the most-followed athletes to emerge from this World Cup, regardless of how his side’s run ultimately ended.

Science Meets Sport

Ortea’s naming choices follow a consistent logic. Rather than picking names at random, he has tied each species to a detail about the player or club being honoured, whether through colour, geography, or timing. The Vozinha naming continues that approach, linking a mollusc found in the Caribbean to a goalkeeper who plays his football thousands of miles away in Africa and Europe.

Species names given in honour of public figures are not unusual in taxonomy, but Ortea’s specific focus on footballers gives his research a public profile that pure marine biology often doesn’t attract. Each naming tends to draw attention back to his broader work cataloguing new mollusc species, work that includes his research around Cape Verde’s coastline.

For Cape Verde, the timing adds another layer of recognition to a tournament that already delivered milestones the country had not reached before. Vozinha’s clean sheet against Spain and the near-miss against Argentina will likely remain the sporting highlights of the run, but the naming of Aldisa vozinha gives the goalkeeper a mark tied to the tournament that will outlast this particular World Cup cycle.

Ortea’s report on the discovery did not indicate whether he plans to name further species after players from this tournament, though his history suggests Vozinha may not be the last footballer to receive this kind of tribute.
