Query: Toxic chemicals in plastic

I've owned and used this iced tea maker for over 5 years now, without knowing that the continued heating cycle that all iced tea and coffee brewers go through to make iced tea and coffee are releasing extremely high amounts of petrochemicals into your tea or coffee. It sad that are FDA relies on data from the petrochemical industry on the safety of their plastics instead of doing their own independent studies.Stick with glass or stainless steel, unless you want to pump you and your loved ones full of carcinogens!
