EU Regulation 1333/2008 mandates the warning 'may have an adverse effect on activity and attention in children' on foods containing Sunset Yellow FCF (E110). The mandate followed the 2007 Southampton Study linking E110 and other azo dyes to hyperactivity.

Coloring agent for orange/yellow foods and drinks.
Why it's flagged
- EU-mandated child-hyperactivity warning label
- azo dye allergy/intolerance reactions
- FDA announced phaseout of petroleum-based synthetic dyes
What regulators actually say
"Foods containing the food colours listed in Annex V shall bear additional labelling 'may have an adverse effect on activity and attention in children'."
"HHS and FDA announced a series of new measures to phase out the use of petroleum-based synthetic dyes in the nation's food supply."
