Scientific Opinion on the safety and efficacy of beta‐carotene as a feed additive for all animal species and categories

open access: yesEFSA Journal, 2012
The use of beta‐carotene is safe for the target animals. Setting a maximum content in feed legislation is not considered necessary. However, this conclusion assumes that triphenylphosphine oxide does not exceed 100 mg/kg additive.
