In June, after issuing its proposed action levels for lead in juice, FDA tightened its Interim Reference Levels (IRLs) for lead to 2.2 µg/day for children and 8.8 µg/day for females of childbearing age—a drop of 27% from the original IRLs it established in 2018. We estimate this change increased the number of children over the IRL for lead from 2.2 million to more than 7 million.
The agency describes IRLs as daily maximum intake levels for lead in food and beverages. FDA scientists said the change was made to match the Centers for Disease Control and Prevention’s (CDC) October 2021 revised blood lead reference value. This value is commonly known as the elevated blood lead level (EBLL). FDA uses the “interim” label in recognition that there is no known safe level of exposure to lead and the neurotoxic harm it can cause. FDA anticipates matching the IRLs to future reductions in CDC’s reference value as the U.S. makes progress in reducing children’s exposure to lead.
We applaud FDA’s decision to tighten the IRLs. It is a good example of the type of continuous improvement to which FDA committed in its Closer to Zero Action Plan, which aims to lower levels of lead, cadmium, mercury, and inorganic arsenic in food that babies and young children eat and drink.
