Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
Laws and loopholes / Government agency
The US 1996 Food Quality Protection Act requires EPA to add an extra 10-fold safety factor on top of the traditional 10-fold uncertainty factor when assessing pesticide risks, specifically to account for prenatal or postnatal developmental toxicity in children, unless child-specific data justify a smaller factor.
Strong evidence: This is a description of the law's requirement, not a claim that the added safety factor has eliminated risk for any specific chemical.

Laws and loopholes / Other evidence
Since 20 July 2010, EU food containing sunset yellow (E 110), quinoline yellow (E 104), carmoisine (E 122), allura red (E 129), tartrazine (E 102) or Ponceau 4R (E 124) must carry the warning 'may have an adverse effect on activity and attention in children', except meat health marks and egg stamping; a food-color finding, not a fragrance one.
Strong evidence: Original 2008 text; later amendments are not in this capture, so check the current consolidated text. The Regulation states no evidence for the warning.
