26 Apr 2019 --- The US Food and Drug Administration (FDA) has doubled down on its 2005 and 2017 decisions to allow the potentially hazardous chemical perchlorate to be added to dry food packaging. Perchlorate is present in plastics used to store dry foods – such as oats and rice – but can block the thyroid gland from taking up iodine, which it needs to make thyroid hormone – a hormone that is essential for fetal and infant brain development, as well as normal metabolism in people of all ages.
