Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a preparation co
nsisting of essential oils of thyme and star anise, and quillaja bark powder (BIOSTRONG
?510 all natural) as a zootechnical feed additive (functio
nal groups: digestibility enhancer; other zootechnical additives) for all poultry species. BIOSTRONG
?510 all natural is a preparation of partially microencapsulated essential oils, quillaja bark powder, dried herbs and dried spices. The additive co
ntains estragole (up to ■■■■? For short-living animals, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) had no safety co
ncerns when the additive is used at the recommended level of 150 mg/kg complete feed for chickens for fattening and other poultry species for fattening. For long-living animals, the use of the additive was co
nsidered of co
ncern owing to the presence of estragole. No safety co
ncern would be expected for the co
nsumer and the enviro
nment from the use of the additive at the recommended use level in feed. The Panel co
ncluded that the additive is corrosive to the eyes but not irritant to skin. It may be a respiratory irritant or dermal or respiratory sensitiser. When handling the additive, exposure of unprotected users to estragole ■■■■ may occur. Therefore, to reduce the risk, the exposure of the users should be minimised. The additive BIOSTRONG
?510 all natural was co
nsidered efficacious for chickens for fattening at the use level 150 mg/kg complete feed. This co
nclusion was extrapolated to all poultry species for fattening or reared for laying/breeding. ■■■■▟/div>
