Safety of natural mixture of dolomite plus magnesite and magnesium-phyllosilicates (Fluidol) for all animal species

The additive under assessment consists of a natural mixture, mainly composed of dolomite (~ 30%), magnesite (~ 20%) and magnesium-phyllosilicates (talc (~ 35%) and chlorite (~ 15%)). In 2016, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) delivered an opinion on the safety and efficacy of natural mixture of dolomite plus magnesite and magnesium-phyllosilicates. The FEEDAP Panel concluded that the additive is safe in complete feed for dairy cows, piglets and pigs for fattening at a maximum concentration of 20,000 mg/kg. However, no conclusions could be drawn for all other animal species/categories. Following this opinion, the European Commission gave the possibility to the applicant to submit complementary information in order to complete the assessment on the safety for all animal species. The applicant answered with a new submission, an analysis of the previous EFSA opinion, but without new data. The FEEDAP Panel considered the arguments made by the applicant, in relation to the tolerance studies with dairy cows and chickens for fattening. No reason was identified to modify the conclusions reached in the previous opinion.
