Safety and efficacy of a feed additive consisting of zinc chelate of amino acids hydrate for all animal species (Zinpro Animal Nutrition (Europe) Inc.)

Following a request from the European Commission, the 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 zinc chelate of amino acids hydrate, brand name Availa^® Zn, for all animal species, based on a dossier submitted for the modification of the terms of the authorisation of the additive. The additive is currently authorised using amino acids derived from soya protein with a minimum content of 10% zinc. The applicant proposed (i) to include amino acids from other sources such as hydrolysed corn gluten, hydrolysed potato protein and hydrolysed poultry feather meal; (ii) to introduce a minimum specification for free amino acids of 17%; (iii) to introduce a tighter specification of the zinc content of 10–11%. The additive, produced using different proposed sources of hydrolysed proteins, complies with the specifications set by Commission Regulation (EU) 2016/1095. The FEEDAP Panel considers that the use of the different proposed sources of hydrolysed proteins (i.e. soy, feather meal, potato and corn gluten) do not modify the conclusions reached in the previous assessments on the safety for the target species, consumers, environment and efficacy of the additive above. Concerning the safety for the users, the additive should be considered as a skin and eye irritant and a skin sensitiser. The additive has a high dusting potential; however, in the absence of data on the concentration of zinc in the dust it is not possible to make the assessment of the exposure by inhalation.

Safety and efficacy of a feed additive consisting of titanium dioxide for all animal species (Titanium Dioxide Manufacturers Association)

Following a request from the European Commission, the EFSA was asked to deliver a scientific opinion on the safety and efficacy of titanium dioxide (TiO2) for all animal species. TiO2 is applied to be used as a sensory additive (functional group: colourants; i) substances that add or restore colour in feedingstuffs). The specification for TiO2 used as feed additive meets the specifications of TiO2 used as food additive. The EFSA Panel on Food Additive and Flavourings (FAF) concluded that TiO2 (E171) can no longer be considered as safe when used as a food additive. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) endorses this conclusion and considers that it also applies to TiO2 as a feed additive for all animal species. TiO2 is absorbed to a low extent; however, particles of TiO2 can accumulate in the body due to their long half-life. The genotoxicity of TiO2 particles cannot be ruled out raising potential concerns on the safety of the additive for the target species (especially for long-living animals and reproductive animals), consumers and user. Considering this fact and the absence of specific data related to its use as a feed additive, the Panel cannot conclude on the safety of TiO2 for the target species, consumers and environment. In the absence of studies with the additive under assessment, the Panel cannot conclude on the assessment of the effects of the additive on eyes and skin. TiO2 is potentially carcinogenic to workers if inhaled. The concern for genotoxicity of TiO2 particles cannot be ruled out, this should be considered as an additional potential concern to users handling the additive. TiO2 is efficacious in colouring the food for cats and dogs at a minimum content of 1%.

Safety and efficacy of a feed additive consisting of ferrous lysinate sulfate for all animal species (Phytobiotics Futterzusatzstoffe GmbH)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of ferrous lysinate sulfate as nutritional feed additive for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) Panel was assigned to this mandate. Based on the results of a tolerance study, the FEEDAP Panel concluded that ferrous lysinate sulfate is safe in chickens for fattening when used up to the current maximum authorised levels of total iron in feed; this conclusion was extrapolated to all animal species and categories, at the respective maximum authorised iron levels in complete feed. The use of ferrous lysinate sulfate in animal nutrition up to the maximum iron content in complete feed authorised in the EU poses no concern to the safety of consumers. The FEEDAP Panel concluded that ferrous lysinate sulfate poses a risk to users by inhalation; the additive is not a dermal irritant, but is irritant to eyes and a skin sensitiser. The FEEDAP Panel considered that the use of ferrous lysinate sulfate in animal nutrition would not pose a risk for the environment. Owing to the limitations in the study provided, the FEEDAP Panel could not conclude on the efficacy of the additive for chickens for fattening, and thus, on the efficacy of ferrous lysinate sulfate for all animal species and categories.

Safety and efficacy of a feed additive consisting of copper chelate of ethylenediamine for all animal species (Zinpro Animal Nutrition (Europe), Inc.)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of copper chelate of ethylenediamine (Copper-EDA-Cl) as a feed additive for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) identified several issues related to the data provided concerning the chemical characteristics of the additive and, based on the information provided from an in vitro dissociation study, considered it unlikely that the additive consists only of copper mono-chelate of EDA but of several coexisting (copper) species. Therefore, in the absence of adequate experimental data and owing to the uncertainties identified, the Panel cannot conclude on its identity and characterisation of the additive. The FEEDAP Panel concludes that the additive is safe for chickens for fattening and reared for laying/breeding but cannot conclude on the safety for other animal species/categories. The FEEDAP Panel cannot conclude on the safety of the additive for the consumer or the environment. The FEEDAP Panel concludes that handling the additive poses a risk to users by inhalation. The additive should be considered as non-irritant for the skin but corrosive for the eyes and a skin sensitiser. The Panel notes the uncertainties on the genotoxicity potential of the additive that might have an impact on the conclusions on the safety for the user. The FEEDAP Panel concludes that the additive is efficacious in providing copper to meet the nutritional requirements of this trace element in all animal species.

Safety and efficacy of a feed additive consisting of iron chelate of ethylenediamine for all animal species (Zinpro Animal Nutrition (Europe), Inc.)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of iron chelate of ethylenediamine (Iron-EDA-Cl) as a feed additive for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) identified several issues related to the data provided concerning the chemical characteristics of the additive. Based on the information provided, the FEEDAP Panel considered unlikely that the additive consists only of iron monochelate of EDA, but of several coexisting (iron) species; therefore, in the absence of adequate experimental data and owing to the uncertainties identified, the Panel cannot conclude on its identity and characterisation. The FEEDAP Panel concludes that the additive is safe for poultry for fattening and reared for laying/breeding, but cannot conclude on the safety for other animal species/categories. The FEEDAP Panel cannot conclude on the safety of the additive for the consumer or the environment. The FEEDAP Panel concludes that handling the additive poses a risk to users by inhalation. The additive should be considered as non-irritant for the skin but irritant for the eyes and skin sensitiser. The FEEDAP Panel cannot conclude on the efficacy of the additive.
