The study claimed that cooking with black plastic utensils exposed users to flame retardants near the EPA's ‘reference dose,’ but a mathematical error inflated the risk assessment.
Joe Schwarcz pointed out that the researchers had miscalculated the EPA exposure limit. They mistakenly reported it as 42,000 instead of the actual 420,000 nanograms.
The original alarm over toxic exposure from black plastic kitchenware spread widely across media. However, after identification of the error, the extensive panic proved unnecessary.
Following the outcry over kitchen utensil safety, the researchers acknowledged their error and published a correction in the study, downgrading the suggested risks significantly.
