These everyday black plastic objects contain carcinogenic substances

In our kitchens, certain items hide unexpected threats. The black plastic of cooking utensils could be more dangerous than it seems. A recent study is raising the alarm.

Toxic chemicals, known as flame retardants, are said to be present in these everyday objects. And this could have serious consequences for our health.


Flame retardants are normally used in electronic devices to prevent fires. But during the recycling of these plastics, they accidentally end up in our kitchen utensils.

The study published in Chemosphere reveals that 85% of the products analyzed, containing more than 50 ppm (parts per million) of bromine, included these toxic compounds. They release carcinogenic and endocrine-disrupting substances when heated. This concerns black products, such as kitchen utensils, but also children's toys, hairbrushes, or even food packaging, for example.

Researchers measured levels of these chemicals well above tolerated limits. Some black plastic spatulas and spoons tested contain up to 22.8 grams (0.8 oz) of flame retardants per kilogram (2.2 lbs). By using these utensils, we might be absorbing 34.7 micrograms of flame retardants per day.

Fortunately, solutions exist. Researchers recommend replacing black plastic utensils with safer alternatives, such as stainless steel or untreated wood. But beware: even wood or silicone is not without risk. It is essential to make sure they are of good quality and not treated with chemicals.

While waiting for stricter regulations, it is better to turn to inert and heat-resistant materials to reduce exposure to these toxic substances.

Why are flame retardants dangerous to health?

Flame retardants are chemical substances added to various materials to slow the spread of fire. They are widely used in electronic products, furniture, and certain everyday items. However, several studies have highlighted their harmful effects on human health.

These compounds often include brominated products (such as decabromodiphenyl ether, or decaBDE), which are of particular concern. Indeed, these substances can accumulate in the human body and are associated with serious issues, such as cancers, hormonal disruptions (endocrine disruptors), and toxic effects on children's development. Prolonged exposure, even at low doses, can lead to a dangerous buildup of these toxic substances in the body.

Recycled plastics used to make certain everyday objects, such as kitchen utensils or toys, can be contaminated by these flame retardants, increasing consumers' risk, especially when these objects are heated or in direct contact with food.
