That black plastic spatula in your kitchen drawer might be harboring toxic flame retardants from recycled electronics that could leach into your family’s food.
The investigation, which examined 203 black plastic products purchased from local Seattle retailers and online platforms between 2020 and 2022, found concerning levels of flame retardants.
The authors said that these toxins are likely introduced to plastic products through plastic recycling.
Electronic Waste: A Source of Contamination
The items researched included 109 kitchen utensils, 36 toys, 30 hair accessories, and 28 food containers, including takeout trays.The researchers identified electronic recycling facilities as the likely source of flame retardants. Electronic plastics often contain flame retardants for safety considerations.
“Plastics from electronics are often recycled and can be incorporated in household items that do not require flame retardancy, resulting in potentially high and unnecessary exposure,” the authors wrote.
The study noted that flame retardants have been found in and around e-waste recycling facilities and in indoor air and dust at formal recycling sites in Canada, China, Spain, and the United States. Soil samples collected near e-waste recycling locations in China and Vietnam also contained the harmful substances.
These findings “provide further evidence” that the recycling of electronics containing flame retardants leads to exposure for both humans and the environment, the researchers wrote.
Of the items investigated, beaded necklaces made for children registered the highest level of flame retardants, at 22,800 milligrams per kilogram, Liu said.
“Children are a vulnerable population, and it is really concerning to think that they could be exposed to these flame retardants that are associated with carcinogenicity, endocrine disruption, neurotoxicity, and reproductive and developmental toxicity at early ages,” Liu said.

Electronic products that are manufactured with flame retardants, such as DecaBDE, have been shown to cause severe adverse health effects, including neurotoxicity, endocrine disruption, and cancer.The study authors point to three main issues—the continuous use of hazardous flame retardants in widely produced consumer products, lack of restriction on their use, and poorly controlled recycling practices—as the root cause of the contamination of the items in contact with food and children.
“We can’t shop our way out of the problem, and what we really need are restrictions on the most harmful chemicals and materials, such as toxic flame retardants and hazardous plastics, at both the corporate and government level,” Liu said.
According to Liu, safer alternatives exist. “Having restrictions in place will help move the market toward safer solutions,” she said. “We need restrictions to turn off the tap on harmful chemicals and plastics, which will help protect the health of everyone, especially vulnerable populations such as women and children.”
