RESUMEN

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 a zootechnical feed additive for laying hens and minor poultry species for fattening and laying. 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 laying hens and minor poultry species for fattening and laying, consumers and the environment. 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 both 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.

RESUMEN

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.

RESUMEN

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application of renewal of Levilactobacillus brevis DSM 16680 as a technological feed additive (functional group: silage additives) for all animal species. The applicant has provided evidence that the additive currently on the market complies with the existing terms of the authorisation. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive remains safe for all animal species, consumers and the environment. Regarding user safety, the additive should be considered as an eye irritant and 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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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) and endo-1,3(4)-beta-glucanase (produced with T. reesei MUCL 49754) (AveMix® XG 10/AveMix® XG 10 L) as a zootechnical feed additive for weaned and suckling piglets. The additive is already authorised for use in 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 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.

RESUMEN

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.

RESUMEN

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).

RESUMEN

The food enzyme leucyl aminopeptidase (EC 3.4.11.1) is produced with the genetically modified Aspergillus oryzae strain NZYM-BU by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme is free from viable cells of the production organism and its DNA. It is intended to be used in five food manufacturing processes. Dietary exposure to the food enzyme TOS was estimated to be up to 1.508 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 4,928 mg TOS/kg bw per day, the highest dose tested, which, when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 3,268. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. The Panel considered that the risk of allergic reactions by dietary exposure cannot be excluded, but the likelihood is low. Based on the data provided, the Panel concluded that the food enzyme does not give rise to safety concerns under the intended conditions of use.

RESUMEN

The food enzyme carboxypeptidase D (EC 3.4.16.6) is produced with the genetically modified Aspergillus oryzae strain NZYM-MK by Novozymes A/S. It is free from viable cells of the production organism and its DNA. The genetic modifications do not give rise to safety concerns. The food enzyme is intended to be used in five food manufacturing processes. Dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.908 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 2220 mg TOS/kg bw per day, the highest dose tested, which, when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 2445. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and two matches were found, one with a food allergen (wheat). The Panel considered that a risk of allergic reactions upon dietary exposure to this food enzyme, particularly in individuals sensitised to wheat, cannot be excluded, but will not exceed that of wheat consumption. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

RESUMEN

Sodium propionate is authorised containing at least 98.5% of sodium propionate. The applicants requested for the renewal of the authorisation of sodium propionate when used as a feed additive for all terrestrial animal species. The applicant has provided evidence that the additive in the market complies with the conditions of the authorisation. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) confirms that the use of sodium propionate under the current authorised conditions of use is safe for the target species, the consumers and the environment. Considering the user safety, the additive is corrosive to skin, eyes and respiratory tract, but is not a skin sensitiser. There is no need for assessing the efficacy of the additive in the context of the renewal of the authorisation.

RESUMEN

The food enzyme 3-phytase (myo-inositol-hexakisphosphate 3-phosphohydrolase EC 3.1.3.8) is produced with the non-genetically modified Aspergillus niger strain PHY93-08 by Shin Nihon Chemical Co., Ltd. The food enzyme is free from viable cells of the production organism. It is intended to be used in nine food manufacturing processes. Since residual amounts of food enzyme-total organic solids (TOS) are removed in two of the food manufacturing processes, dietary exposure was calculated only for the remaining seven processes. It was estimated to be up to 0.763 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not raise safety concerns. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 2560 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 3355. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no matches were found. The Panel considered that the risk of allergic reactions upon dietary exposure cannot be excluded, but the likelihood is low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

RESUMEN

The food enzyme triacylglycerol lipase (triacylglycerol acylhydrolase; EC 3.1.1.3) is produced with the non-genetically modified Penicillium caseifulvum strain AE-LRF by Amano Enzyme Inc. The food enzyme was free from viable cells of the production organism. It is intended to be used in four food manufacturing processes. Dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.013 mg TOS/kg body weight (bw) per day in European populations. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 69 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 5308. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. However, the Panel noted that traces of ■■■■■, used in the manufacture of the triacylglycerol lipase, may be found in the food enzyme. The Panel considered that the risk of allergic reactions upon dietary exposure could not be excluded, particularly in individuals sensitised to fish. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns, under the intended conditions of use.

RESUMEN

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 concentrated liquid l-lysine, l-lysine monohydrochloride and concentrated liquid l-lysine monohydrochloride produced by a genetically modified strain of Escherichia coli (NITE BP-02917) as nutritional and as sensory (flavouring compound) feed additives for all animal species. In 2022, the FEEDAP Panel issued an opinion on the safety and efficacy of these products. In that assessment, the FEEDAP Panel could not exclude the potential presence of recombinant DNA derived from the genetically modified production organism in the products. The applicant provided supplementary data to exclude the presence of recombinant DNA derived from the production organism in the final products. Based on the new data provided, the FEEDAP Panel concluded that no DNA of the production strain E. coli NITE BP-02917 was detected in concentrated liquid l-lysine, l-lysine monohydrochloride and concentrated liquid l-lysine monohydrochloride.

RESUMEN

The food enzyme pectinesterase (pectin pectylhydrolase; EC 3.1.1.11) is produced with the genetically modified Aspergillus oryzae strain AR-962 by AB Enzymes GmbH. The genetic modifications did not give rise to safety concerns. The food enzyme was free from viable cells of the production organism and its DNA. It is intended to be used in five food manufacturing processes: fruit and vegetable processing for juice production, fruit and vegetable processing for products other than juice, production of wine and wine vinegar, production of plant extracts as flavouring preparations and coffee demucilation. Since residual amounts of total organic solids are removed by repeated washing or distillation, dietary exposure to the food enzyme total organic solids (TOS) from the production of flavouring extracts and coffee demucilation was considered not necessary. For the remaining three food processes, dietary exposure to the food enzyme-TOS was estimated to be up to 0.647 mg TOS/kg bw per day in European populations. Genotoxicity tests did not indicate a safety concern. The systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 1,000 mg TOS/kg bw per day, the highest dose tested, which when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 1,546. A search for the similarity of the amino acid sequence to those of known allergens was made and two matches with pollen allergens were found. The Panel considered that, under the intended conditions of use the risk of allergic reactions by dietary exposure, particularly in individuals sensitised to pollen allergens, cannot be excluded. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.

RESUMEN

The food enzyme 1,4-α-glucan branching enzyme ((1-4)-α-d-glucan:(1-4)-α-d-glucan 6-α-d-[(1-4)-α-d-glucano]-transferase; EC 2.4.1.18) is produced with the non-genetically modified Geobacillus thermodenitrificans strain TRBE14 by Nagase (Europa) GmbH. The production strain has been shown to qualify for the qualified presumption of safety (QPS) approach. The food enzyme is intended to be used in cereal-based processes, baking processes as well as meat and fish processing. Dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.29 mg TOS/kg body weight (bw) per day in European populations. Toxicological studies were not considered necessary given the QPS status of the production strain and the nature of the manufacturing process. A search for the similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. The Panel noted that the food enzyme contains lysozyme, a known allergen. Therefore, allergenicity cannot be excluded. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns, under the intended conditions of use.

RESUMEN

The food enzyme glucan-1,4-α-glucosidase (4-α-d-glucan glucohydrolase; EC 3.1.2.3) is produced with the non-genetically modified Rhizopus delemar strain CU634-1775 by Shin Nihon Chemical Co., Ltd. The food enzyme is free from viable cells of the production strain. It is intended to be used in six food manufacturing processes: baking processes, starch processing for production of glucose syrups and other starch hydrolysates, fruit and vegetable processing for juice production, fruit and vegetable processing for products other than juices, brewing processes and distilled alcohol production. As residual amounts of total organic solids (TOS) are removed by distillation and by the purification steps applied during the production of glucose syrups, dietary exposure was not calculated for these two food processes. For the remaining four food processes, dietary exposure to the food enzyme-total organic solids was estimated to be up to 1.238 mg TOS/kg body weight (bw) per day. Genotoxicity tests did not raise a safety concern. Systemic toxicity was assessed by means of a repeated dose 90-day oral toxicity study in rats. The Panel identified a no observed adverse effect level of 1,735 mg TOS/kg bw per day, the highest dose tested, which, when compared with the estimated dietary exposure, resulted in a margin of exposure of at least 1,401. In a search for the similarity of the amino acid sequence of the food enzyme to known allergens, a single match with a respiratory allergen was found. The Panel considered that, under the intended conditions of use, the risk of allergic reactions by dietary exposure cannot be excluded, but the likelihood is low. Based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
