Safety of the feed additive consisting of chromium propionate (KemTRACE Chromium 0.4% MT) for chickens for fattening, chickens reared for laying/reproduction, turkeys for fattening and turkeys reared for reproduction (Kemin Europa N.V.)

open access: yesEFSA Journal, Volume 24, Issue 7, July 2026.
Abstract An assessment of the safety and efficacy of a feed additive consisting of chromium propionate (KemTRACE™ Chromium) was issued on 18 March 2021. Due to difficulties in implementing the proposed method for the official control of added organic chromium in premixtures and feed, the additive needed incorporating a tracer in the composition of a ...
