Little follow-up when FDA finds high levels of perchlorate in food

For more than 40 years, the Food and Drug Administration (FDA) has conducted the Total Diet Study (TDS) to monitor levels of approximately 800 pesticides, metals, and other contaminants, as well as nutrients in food. The TDS’s purposesare to “track trends in the average American diet and inform the development of interventions to reduce or minimize risks, when needed.” By combining levels of chemicals in food with food consumption surveys, the TDS data serve a critical role in estimating consumers’ exposure to chemicals.

From 2004 to 2012 (except for 2007), FDA collects and tests about 280 food types for perchlorate, a chemical known to disrupt thyroid hormone production. This information is very important, because for the many pregnant women and children with low iodine intake, even transient exposure to high levels of perchlorate can impair brain development.
