RESUMO

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 liquid l-lysine base produced with a genetically modified strain of Corynebacterium glutamicum as a nutritional feed additive for all animal species. The l-lysine base liquid produced with C. glutamicum NRRL B-67535 and NRRL B-67439 is currently authorised as a nutritional additive for all animal species. The present application is aimed at modifying the current authorisation to include C. glutamicum NRRL B-68248 as a production strain. The new production strain qualifies for the qualified presumption of safety approach when used for production purposes. It was unambiguously identified as C. glutamicum and was shown not to harbour acquired antimicrobial resistance determinants for antibiotics of human and veterinary importance. All the introduced sequences or mutations were considered to be safe, and no viable cells or DNA of the NRRL B-68248 strain was detected in the final product. Therefore, the final product does not pose any safety concern associated with the production strain. l-Lysine base produced using C. glutamicum NRRL B-68248 does not represent a risk for the target species, the consumer or the environment. The additive was considered to be neither irritant to skin or the eyes, nor a dermal sensitiser. l-Lysine base produced with C. glutamicum NRRL B-68248 is considered to be 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.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the feed additive consisting of endo-1,4-beta-xylanase (produced with Trichoderma reesei MUCL 49755) and endo-1,3(4)-beta-glucanase (produced with T. reesei MUCL 49754) (AveMix® XG 10/AveMix® XG 10 L) for the renewal of its authorisation as zootechnical feed additive for pigs for fattening, minor porcine species for fattening and turkeys for fattening. The applicant declared a change in the carrier material used in AveMix® XG 10 from soybean meal to calcium carbonate + wheat flour or calcium carbonate + sepiolite. The applicant provided evidence that the additive Avemix® XG 10 with calcium carbonate + wheat flour and Avemix® XG 10 L comply with the conditions of the authorisation. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) noted that no data were submitted to support compliance of the formulation of Avemix® XG 10 with calcium carbonate + sepiolite with the conditions of the authorisation. The FEEDAP Panel concluded that both forms of the additive remain safe for pigs for fattening, minor porcine species for fattening and turkeys for fattening, consumers and the environment. Regarding the safety for the user, Avemix® XG 10 formulated with calcium carbonate + sepiolite and Avemix® XG 10 L are not irritant to skin and eyes. No conclusions on the irritation potential of Avemix® XG 10 formulated with calcium carbonate + wheat flour could be drawn. The additive in all its formulations is considered a respiratory and skin sensitiser. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety of the feed additive consisting of endo-1,4-ß-xylanase (produced with Trichoderma reesei CBS 143953), subtilisin (produced with Bacillus subtilis CBS 143946) and α-amylase (produced with Bacillus amyloliquefaciens CBS 143954) (Avizyme® 1505) as a zootechnical feed additive for all poultry species. The additive is authorised in feed for chickens and turkeys for fattening, ducks and laying hens. In 2020, the FEEDAP Panel issued an opinion for the renewal of the authorisation of the additive for the species/categories for which there is an authorisation, a reduction of the minimum recommended level in turkeys for fattening and the extension of use to all poultry species. In that assessment, the Panel could not conclude on the safety of the additive due to uncertainties on the characterisation of the production strains and the possible presence of their viable cells and DNA in the final product. Moreover, limitations were identified in the xylanase specifications and xylanase method of analysis. The applicant submitted information to address the limitations previously identified. The Panel concluded that the additive is safe for the target species under the proposed conditions of use. The use of Avizyme® 1505 in animal nutrition is considered safe for the consumer and the environment. The additive is a mild irritant to skin and eyes; it is not a dermal sensitiser but should be considered a respiratory sensitiser. The additive is efficacious in ducks at 75 U endo-1,4-ß-xylanase, 1000 U subtilisin and 100 U α-amylase/kg of complete feed. In other poultry species for fattening (including turkeys), reared for breeding and reared for laying, the additive is efficacious at 187.5 U endo-1,4-ß-xylanase, 2500 U subtilisin and 250 U α-amylase per kg of complete feed and at 300 U endo-1,4-ß-xylanase, 4000 U subtilisin and 400 U α-amylase per kg of complete feed for all poultry species for laying (except for ducks).

RESUMO

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 endo-1,4-beta-xylanase (produced with Trichoderma reesei MUCL 49755), endo-1,3(4)-beta-glucanase (produced with T. reesei MUCL 49754) and polygalacturonase (produced with Aspergillus fijiensis CBS 589.94) (AveMix® 02 CS/ AveMix® 02 CS L) as a zootechnical feed additive for weaned and suckling piglets. The additive is already authorised for use with weaned piglets. This scientific opinion concerns the request for the renewal of the authorisation of the additive for weaned piglets and the extension of use to suckling piglets. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. There was no new evidence that would lead the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) to reconsider its previous conclusions that the additive is safe for weaned piglets, the consumer and the environment under the authorised conditions of use. This conclusion applied also to the new target species (suckling piglets) for which a request for an extension of use was made. The additive in both formulations (powder and liquid) is not irritant to skin or eyes but should be considered a dermal and respiratory sensitiser. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation for weaned piglets. The Panel concluded that the additive is efficacious in suckling piglets at 2140 XU, 1230 BGU and 46 PGLU/kg complete feed.

This scientific opinion concerns the request for the renewal of the authorisation of the additive for weaned piglets and the extension of use to suckling piglets. The applicant declared a change in the carrier material used in AveMix® XG 10 from soybean meal to calcium carbonate + wheat flour or calcium carbonate + sepiolite. The applicant provided evidence that the additive AveMix® XG 10 with calcium carbonate + wheat flour and AveMix® XG 10 L comply with the conditions of the authorisation. The EFSA Panel on Additives and Products or Substances used in Animal FEED (FEEDAP) noted that no data were submitted to support compliance of the formulation of AveMix® XG 10 with calcium carbonate + sepiolite with the conditions of the authorisation. The FEEDAP Panel concluded that both formulations of the additive (powder and liquid) remain safe for the target species, consumers and the environment, and that the extension of use to suckling piglets would not affect these conclusions. AveMix® XG 10 formulated with calcium carbonate + sepiolite and AveMix® XG 10 L are not irritant to skin and eyes. No conclusions on the irritation potential of AveMix® XG 10 formulated with calcium carbonate + wheat flour could be drawn. The additive in all its formulations is considered a respiratory and skin sensitiser. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation for weaned piglets. The Panel concluded that the additive is efficacious in suckling piglets at 4000 XU and 900 BGU/kg complete feed.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the characterisation of the feed additive consisting of vitamin B12 (cyanocobalamin) produced by fermentation with Ensifer adhaerens (CGMCC 19596). The additive is intended to be used as a nutritional additive for all animal species. In a previous opinion, the FEEDAP Panel could not conclude on the characterisation of the production strain, due to uncertainties on whether the production strain E. adhaerens CGMCC 19596 was genetically modified. However, since viable cells and DNA were not detected in the product, the FEEDAP Panel concluded that vitamin B12 (cyanocobalamin), produced with E. adhaerens CGMCC 19596 would not raise safety concerns as regards the production strain. In the present submission, the applicant provided supplementary information regarding the origin and history of modifications of the strain. Based on the data provided, the FEEDAP Panel concluded on the characterisation of the production strain E. adhaerens CGMCC 19596, which can be considered not to be genetically modified.

RESUMO

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.

RESUMO

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 Bacillus velezensis ATCC PTA-6737 as a zootechnical additive (functional group: gut flora stabilisers) in regard to the renewal of the authorisation for weaned piglets, weaned minor porcine species, sows and minor reproductive Suidae species, and its extension of use for all Suidae. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. The Panel concluded that there is no new evidence that would lead it to reconsider the previous conclusions; the additive is safe for the target species, consumers and the environment under the authorised conditions of use. This conclusion also applies to the target species/categories for which a request for an extension of use is made. The Panel concluded that B. velezensis ATCC PTA-6737 is not irritant to skin or eyes but should be considered a respiratory sensitiser due to its proteinaceous nature. No conclusions could be drawn on the skin sensitisation potential of the additive. The Panel concluded that the additive has the potential to be efficacious in all growing Suidae (suckling, weaned and fattening Suidae) at the minimum inclusion level of 1 × 107 CFU/kg of complete feed and in sows and minor reproductive Suidae species at 1 × 108 CFU/kg complete feed.

RESUMO

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 Bacillus velezensis ATCC PTA-6737 as a zootechnical additive (functional group: gut-flora stabiliser) in the context of the renewal of the authorisation for turkeys for fattening and turkeys reared for breeding. The applicant is also requesting to modify the target species in the current authorisations to 'all growing poultry', the increase of the recommended use level in chickens for fattening, chickens reared for laying and minor poultry species except minor poultry for laying from 1 × 107 to 1 × 108 CFU/kg complete feed and the compatibility of the additive with halofuginone. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. There was no new evidence that would lead to reconsider previous conclusions. Therefore, the FEEDAP Panel concluded that the additive remains safe for all poultry species for fattening and reared for laying/breeding, the consumers and the environment under the current authorised conditions of use. The additive is not irritant to the skin and eyes, but it should be considered a respiratory sensitiser. The Panel could not conclude on the skin sensitisation potential of the additive. The Panel concluded that the additive has a potential to be efficacious as a zootechnical additive for poultry for fattening and reared for laying/breeding under the proposed conditions of use.

RESUMO

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 Saccharomyces cerevisiae MUCL 39885 (Biosprint®) as a feed additive for cattle for fattening (category: zootechnical; functional group: gut flora stabiliser). The applicant provided evidence that the additive currently in the market complies with the conditions of authorisation. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) confirmed that the use of Biosprint® under the current authorised conditions of use remains safe for the target species, the consumers and the environment. Taking into account the nature of the additive, the FEEDAP Panel concludes that the additive should be considered as a potential skin and respiratory sensitiser, and any exposure through skin and respiratory tract is considered a risk. The additive is not a skin/eye irritant. There is no need to assess the efficacy of Biosprint® in the context of the renewal of the authorisation.

RESUMO

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.

RESUMO

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.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of authorisation of a preparation of dried cells of Saccharomyces cerevisiae CNCM I-4407 (Actisaf® Sc 47) as a zootechnical additive for rabbits for fattening and non-food producing rabbits. The applicant provided evidence that the additive currently in the market complies with the existing terms of the authorisation. The Panel concluded that the additive remains safe for the target species, consumers and the environment. Regarding the safety for the user, the additive is not a skin or eye irritant. However, it should be considered as a potential skin and respiratory sensitiser, and any exposure through skin and respiratory tract is considered a risk. The present application for renewal of the authorisation did not include a proposal for amending or supplementing the conditions of the original authorisation that would have an impact on the efficacy of the additive. Therefore, there was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of muramidase produced with Trichoderma reesei DSM 32338 (Balancius™) as a feed additive for laying hens. The additive is already authorised as a zootechnical additive (functional group: other zootechnical additives) for chickens, turkeys and minor poultry species for fattening or reared for breeding, and for weaned piglets. The enzyme is produced by fermentation with a genetically modified strain of Trichoderma reesei; viable cells of the production strain and its recombinant DNA were not detected in the additive. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive does not give rise to safety concerns regarding the genetic modification of the production strain. Based on the data available from a sub-chronic oral toxicity study, the Panel concluded that the additive is safe for laying hens at the maximum recommended level of 60,000 LSU(F) (muramidase activity units)/kg feed. The Panel also concluded that the additive is safe for the consumers and the environment. The liquid formulation of the additive is considered not irritant to the skin or eyes. The solid formulation of the additive is considered not irritant to the skin. The Panel cannot conclude on the potential of the additive (both formulations) to be a dermal sensitiser or on the potential of the solid formulation to be irritant to the eyes. Due to the proteinaceous nature, both forms of the additive should be considered respiratory sensitisers. The additive has the potential to be efficacious as a zootechnical additive for laying hens at 30,000 LSU(F)/kg feed.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of 6-phytase (Quantum® Blue) as a zootechnical feed additive for fin fish. The additive is authorised for use in poultry and pigs. The additive is available in solid and liquid forms, and the 6-phytase contained in the product is produced by fermentation with a genetically modified strain of Trichoderma reesei. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the genetic modification of the production strain does not give rise to safety concerns; viable cells of the production strain and its DNA were not detected in the final products. The FEEDAP Panel concluded that, based on the data available, the additive tested is safe for fin fish at the highest recommended level of 2500 phytase activity unit (FTU)/kg complete feed. The Panel concluded that Quantum® Blue is not an irritant to skin and eyes nor a skin sensitiser. Owing to the proteinaceous nature of the active substance, 6-phytase (Quantum® Blue) is considered a respiratory sensitiser. The use of Quantum® Blue as a feed additive is considered safe for the environment. The additive is considered to be efficacious as a zootechnical additive for salmonids and ornamental fish at 500 FTU/kg complete feed and other fin fish at 2500 FTU/kg complete feed.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the coccidiostat salinomycin sodium (Sacox®) for rabbits for fattening. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the use of salinomycin sodium (SAL-Na) from Sacox® does not raise safety concerns for the target species, consumers, users and the environment with regard to the production strain. In the absence of adequate tolerance studies, the FEEDAP Panel could not conclude on the safety of SAL-Na from Sacox® for rabbits for fattening. The FEEDAP Panel concluded that the additive is safe for the consumer when it is used at the proposed maximum level of 25 mg SAL-Na/kg complete feed for rabbits and a withdrawal period of 1 day is respected. The following maximum residue limits (MRL) are proposed for the marker residue compound salinomycin (SAL): 0.2 and 0.03 mg SAL/kg for liver and kidney, respectively. The additive is not irritant to skin and eyes but should be considered a potential dermal and respiratory sensitiser. A risk for inhalation toxicity could not be excluded. The use of the SAL-Na from Sacox® in feed for rabbits for fattening up to the highest proposed level will not pose a risk for the terrestrial and aquatic compartment and ground water. The risk of secondary poisoning can be excluded for worm-eating birds and mammals, while it cannot be excluded for fish-eating birds and mammals. The FEEDAP Panel concludes that SAL-Na from Sacox® at the minimum concentration of 20 mg SAL-Na/kg complete feed has the potential to control coccidiosis in rabbits for fattening. Development of resistance to SAL-Na of field Eimeria spp. strains isolated from rabbits for fattening should be monitored.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the alpha-amylase (Ronozyme® HiStarch CT/L) produced with a genetically modified strain of Bacillus licheniformis (DSM 34315) as a zootechnical feed additive for chickens for fattening, turkeys for fattening and minor growing poultry species. The additive is available in two forms, a coated thermotolerant granulate formulation and a liquid formulation. The production strain and its DNA were not detected in an intermediate concentrated product representative of the final formulations. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the final product did not trigger safety concerns with regard to the genetic modification. The Panel concluded that Ronozyme® HiStarch CT/L is safe for chickens for fattening, turkeys for fattening and minor growing poultry species at the recommended inclusion level of 80 KNU/kg complete feed. The use of Ronozyme® HiStarch CT/L in animal nutrition under the proposed conditions of use is safe for the consumers and the environment. The additive in any form was shown to be non-irritant to the skin and the solid form was shown to be non-irritant to the eyes. No conclusions could be drawn on the potential of the liquid form to be irritant to the eyes or on the potential of both forms of the additive to be dermal sensitisers due to lack of data. Owing to the proteinaceous nature of the active substance, the additive in either form was considered to be a respiratory sensitiser and any exposure by inhalation is considered a risk. In the absence of data, the Panel was not in the position to conclude on the efficacy of Ronozyme® HiStarch CT/L for chickens for fattening, turkeys for fattening and minor growing poultry species.

RESUMO

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.

RESUMO

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.
