Published research: what individual studies found

These are findings from individual published studies and food-safety agency opinions, credited to each paper. Each one is labeled by type of evidence. They do not change any verdict, evidence grade or score on this site.

Evidence type: EFSA re-evaluation (2010)

• EFSA (2010) estimated that, assuming maximum permitted use levels (Tier 2), children at the 95th/97.5th percentile may exceed the ADI (5 mg/kg bw/day) for Green S; the refined Tier 3 estimate was below the ADI.
• About the ADI: An ADI is a safety benchmark with a built-in margin. An estimate above it is not a measured intake and doesn't mean harm has occurred.
