aThese exposure estimates do not incorporate information on organic consumption habits; they are based exclusively on self-reported produce intake and residue levels in foods. The higher exposure estimates among individuals reporting that they “often or always” consume organic food is reflective of the fact that this group eats more produce than those who eat organic food less frequently or not at all.
