Article says flame retardants are added to recycled plastic, not virgin plastic.
At the end of the article, the author states this is why she does not recycle her old black plastic.
Your reading and comment of that is sophomoric.
Frankly, the idea of using recycled plastic with no control for its origin for cooking utensils looks weird to me. OTOH it should look like a great opportunity to cut costs, and shoppers very often try to save that last cent as a matter of principle and sport, so...
Coffee machines from reputable makers should be safe, I think.
This is evidenced in https://www.sciencedirect.com/science/article/abs/pii/S00489...
"To investigate the extent to which kitchen utensils are contaminated with BFRs and the potential for resultant human exposure, we collected 96 plastic kitchen utensils and screened for Br content using a hand-held X-ray fluorescence (XRF) spectrometer. Only 3 out of 27 utensils purchased after 2011 contained detectable concentrations of Br (≥ 3 μg/g). In contrast, Br was detected in 31 out of the 69 utensils purchased before 2011."
Let me emphasize: Only 3 out of 27 utensils purchased after 2011 contained detectable concentrations of Br.
Further vital information: "Simulated cooking experiments were conducted to investigate BFR transfer from selected utensils (n = 10) to hot cooking oil, with considerable transfer (20% on average) observed."
Fine, I don't cook with hot oil. I don't melt my utensils when cooking, I don't damage them at all. I see the reason for concern, but for my cooking styles this really doesn't affect me.
