Plastic kitchen utensils often leach toxic chemicals into your food

One of the first things you notice when you step into any kitchen, professional or otherwise, is the myriad of gadgets and tools that make our culinary adventures possible. But what if, hidden among the plastic items, there are potential threats to your food?

A new study was focused specifically black plastic kitchen utensils and containers. The concerns raised aren’t about their functionality but what might lie within them.

Plastic threats in everyday kitchens

This seemingly innocuous yet essential kitchenware triggered the interest of scientists from Duke University who embarked on an exploration to see if these items hold more than meets the eye.

The focus? Toxic flame retardants. Due to their connection to an increased risk of cancer, hormonal disruption, and neurodevelopmental impacts, many flame retardants have been phased out or banned.

Yet, their remnants may be lurking in the very plastic tools we use daily to stir, serve, and store our food.

Chemicals from plastic utensils

As the world continues its well-intentioned push for more recycling, inadvertently, we might be creating an unseen cycle of chemical reincarnation.

Flame retardants are used in products such as TVs that display potential fire risks. During recycling, these chemicals have made their way into kitchenware like spatulas or ladles that do not require such protection.

Dr. Heather Stapleton is a professor of environmental sciences and policy at the Nicholas School of the Environment at Duke University.

“If you find these chemicals in a plastic spatula, does that mean it’s getting out of the spatula and into your food? We don’t have that answer yet,” said Dr. Stapleton. “Is it possible? Absolutely.”

Dr. Stapleton explained that when plastic is heated, it leaches chemicals into the environment around it – such as your favorite chili or stir-fry.

Certain foods, particularly those with high fat content, can draw more of the chemicals out, raising concerns about daily exposure.

Sushi trays: Convenient yet concerning

Grocery store sushi trays were flagged as significant sources of harmful chemicals.

These convenient carriers displayed high levels of toxic substances, which, combined with prolonged food contact, could lead to potential exposure.

“As an exposure scientist thinking about contact with food and the likelihood these chemicals will leach out in significant amounts, I think there could be some exposure there,” said Dr. Stapleton. “But I don’t know that it’s going to be significant enough to raise concern.”

Further research is needed, and Dr. Stapleton has already begun analyzing the sushi trays.

Plastic spatulas and trays for food

The study did not incite panic among the researchers. Instead, it led them to implement personal changes while addressing the broader issue.

Study lead author Megan Liu highlighted the importance of policy changes to ensure transparency in recycling processes and eliminate these chemicals at the source.

Both scientists acknowledged the need for companies to act and governments to ban these hazardous substances.

In response to the study, Liu swapped her black plastic storage containers for glass ones.

While Dr. Stapleton still retains a single black spatula in her kitchen (to preserve her non-stick pan), she balances practicality with precaution, advising people to exercise moderation and not worry excessively.

Steps to keep your kitchen safe

Those seeking solace from these unsettling revelations can initiate a few changes right away.

Discarding black plastic takeout containers labeled “No. 6” is recommended. These appear to contain particularly high levels of harmful chemicals.

Another empowering step is to support companies ushering positive change in dealing with hazardous substances.

With the results of the study in mind, opting for wooden or stainless-steel utensils emerges as a safer bet.

What about silicone?

Silicone utensils, often promoted as a safer alternative, also warrant a second glance.

The material’s propensity to attract chemicals from the environment could inadvertently lead to them landing in your food. Though washing could help, it may not eliminate many of the airborne chemicals.

Taking all of this into account, it might be time to review your plastic and other kitchen utensils, not just for their utility but also for their impacts on food and health.

If you are planning a switch, consider exploring wooden, stainless-steel, and bamboo utensils as non-toxic alternatives.

The full study was published in the journal Chemosphere.
