ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of the authorisation of l-cystine as nutritional feed additive. The additive is authorised for use in all animal species (3c391). The applicant has provided evidence that the additive currently in the market complies with the existing conditions of authorisation. The EFSA Panel on Additives and Products or Substances used in Animal Feed concluded that the use of the feed additive in animal nutrition remains safe for the target species, the consumers and the environment. As regards the safety for the user, l-cystine is not an irritant to skin or eyes and is not a skin sensitiser. Exposure by inhalation of persons handling the additive cannot be excluded. The present application for the renewal of the authorisation does not include any modification proposal that would have an impact on the efficacy of the additive and therefore there is no need for reassessing the efficacy.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of l-threonine produced by fermentation with Escherichia coli CGMCC 7.455 when used as a nutritional additive in feed and water for drinking for all animal species and categories. The production strain is genetically modified. None of the introduced genetic modifications raised a safety concern. Viable cells of the production strain and its DNA were not detected in the final additive. Therefore, the final product does not give raise to any safety concern regarding the genetic modification of the production strain. The use of l-threonine (≥ 98.5%) produced with E. coli CGMCC 7.455 to supplement feed is safe for the target species. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) has concerns on the safety of the simultaneous oral administration of l-threonine via water for drinking and feed due to possible amino acid imbalances and hygienic reasons. The use of l-threonine produced with E. coli CGMCC 7.455 in animal nutrition raises no safety concerns to consumers of animal products and to the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be irritant to skin or eyes, or on its potential to be a dermal sensitiser. The endotoxin activity in the additive does not pose a risk for the user via inhalation. The additive l-threonine is regarded as an effective source of the amino acid l-threonine for all non-ruminant species. In order to be as efficacious in ruminants as in non-ruminants, it should be protected from ruminal degradation.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the selenised yeast (inactivated) Saccharomyces cerevisiae CCTCC M 2022402 (Plexomin® Se 3000, available in two forms: 'granules' and 'micro') as a nutritional feed additive for all animal species. Based on a tolerance-efficacy trial, the FEEDAP Panel concluded that the additive is safe for chickens for fattening at proposed conditions of use and this conclusion can be extrapolated to all animal species. In the absence of deposition data in all animal species and products, the FEEDAP Panel cannot conclude on the safety for the consumer. Plexomin® Se 3000 (granules) is dust-free; therefore, the exposure through inhalation is unlikely. Plexomin® Se 3000 (micro) presents a risk by inhalation. Both forms of the additive (granules and micro) are considered as respiratory sensitisers. Due to the lack of data, no conclusions can be drawn on the dermal and eye irritation potential of Plexomin® Se 3000 (granules). Plexomin® Se 3000 (micro) is not irritant to the skin and the eyes. No conclusions can be drawn on the potential of both forms of the additive to be dermal sensitisers. The use of the additive in animal nutrition is considered safe for the environment. The additive is an efficacious source of selenium in feedingstuffs for all animal species.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of l-tryptophan produced by fermentation with Escherichia coli CGMCC 7.460 when used as a nutritional additive in feed and water for drinking for all animal species and categories. The production strain is not genetically modified. Viable cells of the production strain were not detected in the final additive. The additive does not give rise to any safety concern regarding the production strain. The use of l-tryptophan (≥ 98%) produced with E. coli CGMCC 7.460 to supplement feed is safe for non-ruminant species. There may be a risk for an increased production of toxic metabolites when unprotected tryptophan is used in ruminants. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) has concerns on the safety of the simultaneous oral administration of l-tryptophan via water for drinking and feed due to possible amino acid imbalances and hygienic reasons. The use of l-tryptophan produced with E. coli CGMCC 7.460 in animal nutrition raises no safety concerns to consumers of animal products and to the environment. In the absence of data, the FEEDAP Panel cannot conclude on the potential of the additive to be irritant to skin or eyes, or on its potential to be a dermal sensitiser. The endotoxin activity of the additive in combination with the high dusting potential may represent a risk of exposure by inhalation to endotoxins for users. The additive l-tryptophan is regarded as an effective source of the amino acid l-tryptophan for all non-ruminant species. To be as efficacious in ruminants as in non-ruminants, it should be protected from ruminal degradation.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of l-isoleucine produced by fermentation with Corynebacterium glutamicum CGMCC 20437 as a nutritional feed additive for use in feed and in water for drinking for all animal species. The production strain is non-genetically modified, qualifies for the QPS approach to safety assessment when used for production purposes, is susceptible to the relevant antibiotics and contains no antimicrobial resistance genes of concern. No viable cells of the production strain were detected in the final product. The additive does not give rise to any safety concern regarding the production strain. l-Isoleucine produced by fermentation with Corynebacterium glutamicum CGMCC 20437 is considered safe for the target species, the consumer and the environment. Regarding the use in water, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) reiterates its concerns over the safety for the target species of l-isoleucine administered simultaneously via water for drinking and feed owing to the risk of nutritional imbalances and hygienic reasons. In the absence of data, the FEEDAP Panel is not in a position to conclude on the potential of l-isoleucine produced by fermentation with Corynebacterium glutamicum CGMCC 20437 to be irritant to skin and/or eyes, or as a dermal sensitiser. Due to the high dusting potential, exposure by inhalation is likely. l-Isoleucine produced by fermentation with Corynebacterium glutamicum CGMCC 20437 is considered as an efficacious source of the essential amino acid l-isoleucine for non-ruminant animal species. For the supplemental l-isoleucine to be as efficacious in ruminants as in non-ruminant species, it would require protection against degradation in the rumen.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Enterococcus lactis DSM 22502 as a technological feed additive for all animal species. The applicant provided evidence that the additive currently on the market complies with the existing conditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reconsider its previous conclusions regarding the safety and efficacy of the additive. The FEEDAP Panel concluded that E. lactis remains safe for all animal species, consumers and environment under the authorised conditions of use. Regarding the user safety, the Panel concluded that the additive is not irritating to the skin or eyes. No conclusions can be drawn on the potential of the additive to cause skin sensitisation, but it is considered to be a respiratory sensitiser. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the additive based on fumonisin esterase (Free Yeast® F), produced with a genetically modified strain of Komagataella phaffii. The additive is categorised as a technological feed additive, for the reduction of the contamination of feed by mycotoxins and intended for use in all pigs species (piglets, pigs for fattening, sows and minor growing and reproductive porcine species). It was shown that the production strain and its recombinant genes are not present in the additive. The FEEDAP Panel concluded that the additive is safe for weaned and suckling piglets and pigs for fattening, and all minor growing porcine species up to 60 U/kg complete feed. No conclusions can be drawn on the safety of the additive in sows. The use of the additive in animal nutrition is of no concern for consumer safety. The additive is dust-free, and therefore, respiratory sensitisation/irritation is unlikely. The additive is non-irritant to the eyes and the skin. No conclusion could be made on skin sensitisation. The use of the additive as a feed additive is considered safe for the environment. The Panel concluded that the additive is efficacious as technological feed additive for the reduction of feed contamination by fumonisins, when used at the minimum recommended concentration of 60 U/kg. This conclusion can be extrapolated to all growing and reproductive pigs and other minor porcine species.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a feed additive consisting of Enterococcus lactis NCIMB 11181 (Lactiferm®) as a zootechnical additive (gut flora stabiliser) for chickens for fattening, chickens reared for laying, other poultry species for fattening or reared for laying, and ornamental birds. The additive is available in two formulations: Lactiferm WS200 and Lactiferm Basic 50. The FEEDAP Panel concluded that the use of the additive is safe for chickens for fattening or reared for laying, other poultry species for fattening or reared for laying, and ornamental birds. The Panel also concluded that the use of the feed additive is safe for consumers, and the environment. Lactiferm WS200 is not irritant to skin or eyes. Owing to the proteinaceous nature of the active agent, both formulations of the additive are considered respiratory sensitisers. It was not possible, however, to conclude on the irritancy potential for skin and eyes of the Lactiferm Basic 50 formulation or on the potential of both formulations of the additive to cause skin sensitisation. The efficacy studies submitted did not allow to draw a conclusion on the efficacy of the additive for the target species. Lactiferm® is considered compatible with the coccidiostats monensin sodium and decoquinate.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of endo-1,4-ß-xylanase produced by Komagataella phaffii ATCC PTA-127053 (Xygest™ HT) as a zootechnical feed additive (functional group: digestibility enhancers) for all Suidae at a recommended minimum level of 90,000 U/kg complete feed for pigs in the growing period and 45,000 U/kg complete feed for sows. The production strain is considered suitable for the qualified presumption of safety (QPS) approach to safety assessment. The FEEDAP Panel concluded that the additive is safe at the minimum recommended use level for all growing Suidae and all sows in the lactating phase. Xygest™ HT was considered safe for the consumers and for the environment when used in feed for all Suidae. The additive was considered not to be irritant to eyes and skin, but was considered as a dermal and respiratory sensitiser. In the absence of sufficient data, the FEEDAP Panel was not in the position to conclude on the efficacy of Xygest™ HT for all Suidae.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of the authorisation of Enterococcus lactis NCIMB 11181 (Lactiferm®) as a zootechnical additive for weaned piglets, calves for fattening and calves for rearing. The product under assessment is based on a strain originally identified as Enterococcus faecium. During the current assessment, the active agent has been reclassified as Enterococcus lactis. The additive currently authorised is marketed in two formulations: Lactiferm Basic 50 (a solid formulation to be used in feed), and Lactiferm WS200 (a solid 'water-soluble' formulation to be used in water for drinking). The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. The Panel concludes that the use of Lactiferm® under the authorised conditions of use remains safe for the target species (calves up to 6 months and weaned piglets up to 35 kg), consumers and the environment. The Lactiferm WS200 formulation of the additive is not irritant to skin or eyes. Owing to the proteinaceous nature of the active agent, both formulations of the additive are considered respiratory sensitisers. It is not possible to conclude on the irritating potential for skin and eyes of the Lactiferm Basic 50 formulation or on the potential of both forms of the additive to cause skin sensitisation. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of the authorisation of zinc chloride hydroxide monohydrate as a nutritional feed additive for all animal species (3b609). The applicant reported changes in the production process and requested a change in the specification of the additive. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) confirms that the use of the additive under the current authorised conditions of use is safe for the target species and the consumers. The use of the additive in animal nutrition at the proposed use levels for the terrestrial species and land-based aquaculture systems is considered safe for the environment. The FEEDAP Panel cannot conclude on the safety of the additive for marine sediment compartment, when it is used in sea cages. The additive is an eye irritant, but not irritant to the skin and not a skin sensitiser. The exposure through inhalation is likely, but in the absence of data, the Panel is not in a position to conclude on the risk of exposure by inhalation. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of Cylactin® as zootechnical additive. The active agent of the additive is Enterococcus lactis NCIMB 10415, and three additive formulations currently authorised: Cylactin® LBC G35, Cylactin® LBC ME10 and Cylactin® LBC ME20 plus. The additive is currently authorised in the EU for use in poultry (chickens and minor poultry species for fattening, chickens and minor species reared for laying), calves and kids for rearing and for fattening, sows, suckling and weaned piglets and pigs for fattening. The applicant is now seeking the renewal of its authorisation and the extension of use for chickens and minor poultry species reared for breeding, turkeys for fattening and reared for breeding, ornamental birds, lambs for rearing and for fattening, minor or other ruminants' species for rearing and fattening, minor suckling and weaned Suidae species, pigs and minor Suidae species for fattening, rearing or reproduction. In addition, the applicant is seeking authorisation for use in water for drinking for all above-mentioned target species and categories. The applicant has provided evidence that the additive currently on the market complies with the conditions of authorisation. The FEEDAP Panel concludes that the additive is safe for the target animals, consumers and the environment under the authorised/new proposed conditions of use. The Cylactin® LBC ME10 and LBC ME20 plus are not skin and eye irritants, but no conclusion could be drawn on the potential of Cylactin® LBC G35 to be skin and eye irritant. Moreover, no conclusions could be drawn on the additive skin sensitisation potential. The additive is considered a potential respiratory sensitiser. The efficacy for the new target species/categories as well its use in water was extrapolated from the previous efficacy studies.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for the renewal of the authorisation of dicopper chloride trihydroxide as a nutritional feed additive. The additive is currently authorised for use in all animal species (3b409). The applicant is requesting a modification in the current authorising specification: (i) replacing the alpha crystal form paratacamite with clinoatacamite; (ii) removing the ratio between crystal polymorphs from the authorising specification; (iii) changing the minimum for particles below 50 µm from 1% to 5%. The FEEDAP Panel considers that the proposed modifications do not introduce concern for the safety for the target species and that the additive remains safe for the target species and the consumers when used up to the maximum authorised levels. Regarding the safety for the environment, the use of the additive in feed for terrestrial animals and land-based aquaculture is considered safe under the proposed conditions of use. The data available do not allow the FEEDAP Panel to reach a conclusion on the safety of the additive for marine sediment when it is used in sea cages. The additive is not corrosive to skin, but is an eye and skin irritant. Due to the nickel presence, it is considered a skin and respiratory sensitiser. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of manganese(II)-betaine complex as a nutritional feed additive for all animal species and categories. Based on the tolerance study performed in chickens, the FEEDAP Panel concluded that the additive is safe for chickens for fattening when used up to the maximum proposed level of manganese in feed; this conclusion was extrapolated to all animal species and categories at the corresponding maximum manganese levels in complete feed (100 mg Mn/kg feed for fish and 150 mg Mn/kg feed for all other animal species). The FEEDAP Panel concluded that the use of additive in animal nutrition does not represent a concern for consumer safety or for the environment. The additive is irritant to the eyes, but not irritant to skin. Owing to the presence of nickel the additive is considered to be a dermal and respiratory sensitiser. The Panel concluded that the additive is efficacious as a nutritional additive for all animal species under the proposed conditions of use.

ABSTRACT

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of Agal-Pro BL/BL-L®. The additive is a preparation of alpha-galactosidase produced by a genetically modified strain of Saccharomyces cerevisiae (CBS 615.94) and endo-1,4-beta-glucanase produced by a non-genetically modified strain of Aspergillus niger (CBS 120604). It is intended to be used as a zootechnical additive (functional group: digestibility enhancers) in chickens for fattening in its solid and liquid forms (Agal-Pro BL® and Agal-Pro BL-L®), and in minor poultry species for fattening and chickens reared for laying only in its solid form (Agal-Pro BL®). The applicant has provided evidence that the additive currently on the market complies with the existing conditions of authorisation. There is no new evidence that would lead the FEEDAP Panel to reconsider its previous conclusions. Thus, the Panel concludes that the additive remains safe for the target animals, consumers and the environment under the authorised conditions of use. Regarding user safety, the additive is considered an irritant to the skin and eyes and a dermal sensitiser. Due to the proteinaceous nature of the active substances, it should be considered a respiratory sensitiser. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.
