Regulatory consensus

2 regulatory and scientific bodies have classified C.I. Pigment Red 104. The classifications differ — that's the data.

AgencyYearClassificationNotes
EPA CTX / Genetox—Genotoxicity: positive (Ames: None, 2 positive / 0 negative reports)
EPA CTX / Genetox—Genotoxicity: positive (Ames: None, 2 positive / 0 negative reports)

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
