About Annatto
In pet food labels, annatto is the seed extract behind the yellow-orange tint often seen in cheese-flavored kibbles, treats, and broths.
Annatto is a natural colorant derived from the seeds of the achiote tree commonly used in pet foods to impart yellow-to-orange hues, and it provides negligible nutritional value for dogs and cats aside from trace carotenoid compounds that may have limited antioxidant activity. It is often used as a natural alternative to artificial dyes and is generally regarded as safe, though rare allergic reactions or mild gastrointestinal upset can occur in sensitive animals and manufacturers use it primarily for cosmetic rather than nutritional purposes.

Why it's used
Manufacturers add annatto so a product's color matches consumer expectations, for example giving a cheese-flavored treat its characteristic orange hue, without relying on synthetic dyes. It is valued as a plant-derived alternative to petroleum-based colorants like Yellow 5 or Yellow 6.
Common concerns
- Regulatory concentration limits A 2017 EFSA scientific opinion set maximum norbixin (the active annatto pigment) concentrations of 13 mg/kg complete feed for cats and 16 mg/kg for dogs, indicating regulators view it as tolerable only within bounded amounts rather than without limit.
- Individual sensitivity Some pet owners and veterinary sources report occasional digestive upset or skin irritation in individual animals after exposure to annatto, though this appears to be uncommon and is not systematically documented in controlled studies.
- Purely cosmetic function Annatto contributes color only, not nutrition, so its presence on a label reflects a formulation choice about appearance rather than any dietary purpose.
Also relevant
Because reactions to annatto appear to be individual rather than widespread, a veterinarian can help evaluate whether it is a factor if a pet shows new digestive or skin symptoms after a diet change.
