Safety and efficacy of a feed additive consisting of potassium ferrocyanide for all animal species (K + S KALI GmbH).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of potassium ferrocyanide as a technological feed additive, functional group anticaking agents, for all animal species. The additive potassium ferrocyanide is intended to be used in potassium chloride with a maximum content of 150 mg ferrocyanide anion/kg salt. The use of potassium ferrocyanide is safe, when added to potassium chloride at a maximum content of 150 mg ferrocyanide anions (anhydrous)/kg for: pigs for fattening and lactating sows, sheep, goats, salmon and dogs. In the absence of a margin of safety, the use of potassium chloride according to the proposed conditions of use is not considered to be safe for chickens for fattening, laying hens, turkeys, piglets, veal calf, cattle for fattening, dairy cows, horse, rabbit and cats. In the absence of information on the use of potassium chloride in the diets for any other animal species, no conclusion on a potentially safe level of potassium chloride, supplemented with 150 mg ferrocyanide/kg, can be made. The use of potassium ferrocyanide in animal nutrition is of no concern for consumer safety. The results of in vivo studies showed that potassium ferrocyanide is not irritant to skin and eye and is not a skin sensitiser. However, due to the presence of nickel, the additive should be considered as a respiratory and dermal sensitiser. The available data do not allow the FEEDAP Panel to conclude on the safety of the additive for the soil and the marine environment, while the use of the additive in land-based aquaculture according to the proposed conditions of use is considered of no concern. Potassium ferrocyanide is considered to be efficacious as an anticaking agent when included in potassium chloride at the proposed use levels.

Safety and efficacy of a feed additive consisting of concentrated liquid l-lysine, l-lysine monohydrochloride and concentrated liquid l-lysine monohydrochloride produced by Escherichia coliNITE BP-02917 for all animal species (Metex NoovistaGo).

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of concentrated liquid l-lysine, l-lysine monohydrochloride and concentrated liquid l-lysine monohydrochloride produced by Escherichia coli NITE BP-02917 as nutritional and as sensory (flavouring compound) feed additives for all animal species. The production strain did not carry ■■■■■ antimicrobial resistance genes and no viable cells of the production strain were detected in the final products. ■■■■■ However, since no sequences of concern remained in the production strain, the potential presence of that DNA did not raise safety concerns. The use of the three forms of l-lysine produced by E. coli NITE BP-02917 in supplementing feed to compensate for l-lysine deficiency in feedingstuffs was safe for the target species. This conclusion would also cover the use as a sensory additive. The FEEDAP Panel identified risks of nutritional imbalances and hygienic concerns for amino acids when administered simultaneously in feed and in water for drinking. The use of the three forms of l-lysine produced by E. coli NITE BP-02917 in animal nutrition was considered safe for the consumers and for the environment. Concentrated liquid l-lysine, l-lysine HCl and concentrated liquid l-lysine HCl were not considered to have the potential to cause respiratory toxicity, or skin sensitisation. l-Lysine HCl and concentrated liquid l-lysine HCl were not considered skin and eye irritants. Concentrated liquid l-lysine, due to its high pH, might be corrosive for skin and eyes. The three forms were considered an efficacious source of the essential amino acid l-lysine for non-ruminant animal species. For the supplemental l-lysine to be as efficacious in ruminants as in non-ruminant species, it would require protection against degradation in the rumen. The three forms of the additive were also considered efficacious as feed flavouring compounds under the proposed conditions of use.

Safety and efficacy of a feed additive consisting of l-lysine monohydrochloride and l-lysine sulfate produced by fermentation with Corynebacterium glutamicumCGMCC 17927 for all animal species (Barentz Animal Nutrition B.V.).

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 l-lysine monohydrochloride and l-lysine sulfate produced by Corynebacterium glutamicum CGMCC 17927, when used as a nutritional additive in feed and water for drinking for all animal species. The active substance is l-lysine, and it was produced in two different forms: monohydrochloride (HCl) or sulfate salts. The production strain was genetically modified. Neither viable cells nor recombinant DNA of the production strain were detected in the final products. Therefore, the Panel concluded that the additives did not pose any safety concern regarding the production strain. The use of l-lysine HCl and l-lysine sulfate produced by the strain C. glutamicum CGMCC 17927 in supplementing feed to compensate for l-lysine deficiency in feedingstuffs was safe for the target species. The FEEDAP Panel identified risks of nutritional imbalances and hygienic concerns for amino acids when administered simultaneously in feed and in water for drinking. The use of both forms of l-lysine produced by fermentation using C. glutamicum CGMCC 17927 in animal nutrition was considered safe for the consumers and for the environment. Exposure of users through inhalation to l-lysine HCl and l-lysine sulfate produced with C. glutamicum CGMCC 17927 was considered very likely. In absence of data, the FEEDAP Panel could not conclude on the potential of both forms of the additive to be irritant for skin and eyes or to be dermal sensitisers. l-Lysine HCl and l-lysine sulfate were considered as efficacious sources of the essential amino acid l-lysine for non-ruminant animal species. For the supplemental l-lysine to be as efficacious in ruminants as in non-ruminant species, it would require protection against degradation in the rumen.
