Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of CI-FER™ (ferric citrate chelate) as zootechnical feed additive for suckling and weaned piglets and minor porcine species. The additive is safe for weaned piglets at the recommended level of 500 mg/kg complete feed. This conclusion can be extended to sucking piglets for the period in which solid feed is given and extrapolated to all minor porcine species. No concerns for consumer safety are expected from the use of the additive in piglets and minor porcine species. The FEEDAP Panel considers that the compound under assessment poses a risk to users by inhalation. The product should also be considered as an irritant to skin, eyes and mucous membranes. Due to the presence of nickel, CI-FER™ should also be considered as a dermal and respiratory sensitiser. The supplementation of feed with the additive is not expected to pose an environmental risk. CI-FER™ used at the minimum recommended level of 500 mg/kg feed has the potential to improve zootechnical parameters of weaned piglets. This conclusion can be extended to sucking piglets for the period in which solid feed is given and extrapolated to all minor porcine species.
