In late 2024, many people threw away black plastic kitchen utensils after a study warned that they contained flame retardants from recycled electronics. The study had a mathematical error that overstated the estimated exposure relative to the safety reference dose by a factor of ten. The journal published a correction.
The claim
Coverage said that using contaminated utensils could expose people to amounts approaching the reference dose for a flame retardant called BDE-209.
What the evidence shows
- Arithmetic error. The study miscalculated the reference dose for a 60-kilogram adult, giving 42,000 nanograms per day instead of 420,000. The estimated exposure was therefore under a tenth of the reference dose, not 80 percent of it.
- Flagged by scientists. McGill University's Office for Science and Society publicly identified the error.
- Correction. The authors issued a correction and said the error did not change their broader concern about recycled electronic waste in food-contact products.
Why it matters
A real issue can be overstated by a simple calculation error that few readers check.
