RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Saccharomyces cerevisiae CNCM I-1079 as a zootechnical feed additive for dogs and all other Canidae. The additive is intended for use in feed for dogs and all other Canidae at a proposed minimum inclusion level of 1 × 109 CFU per kg of complete feed. Saccharomyces cerevisiae is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. Since the identity of the active agent has been clearly established and no concerns are expected from other components of the product, the additive is considered safe for the target species. Since the additive is intended to be used only in feed for dogs and other non-food-producing animals, an assessment of the safety for the consumer and the environment is not needed. The non-coated form of the additive was shown to be non-irritant to skin and eyes. No conclusion can be drawn on the eye irritation potential of the coated form of the additive due to the lack of data. The additive in both forms, should be considered a skin and respiratory sensitiser and any exposure through skin and respiratory tract is considered a risk. The Panel was not in the position to conclude on the efficacy of Saccharomyces cerevisiae CNCM I-1079 at the proposed conditions of use.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Macleaya cordata (Willd.) R. Br. extract and leaves (Sangrovit® Extra) as a zootechnical feed additive for suckling and weaned piglets and other growing Suidae. The additive is standardised to contain a concentration of the sum of the four alkaloids sanguinarine, chelerythrine, protopine and allocryptopine of 1.25%, with 0.5% sanguinarine. Owing to the presence of the DNA intercalators sanguinarine and chelerythrine, a concern for genotoxicity was identified. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) had no safety concerns for the target species when the additive is used at the recommended level of 0.750 mg sanguinarine/kg complete feed for suckling and weaned piglets and other growing Suidae. Since in all consumer categories the exposure to sanguinarine and chelerythrine via the use of Sangrovit® Extra exceeds the threshold of toxicological concern of 0.0025 µg/kg bw per day for DNA reactive mutagens and/or carcinogens, the FEEDAP Panel could not conclude on the safety for the consumers. The additive was shown to be irritant to the eyes but not irritant to skin or a skin sensitiser. The FEEDAP Panel could not exclude the potential of the additive to be a respiratory sensitiser. When handling the additive, exposure of unprotected users to sanguinarine and chelerythrine may occur. Therefore, to reduce the risk, the exposure of users should be reduced. The use of Sangrovit® Extra as a feed additive under the proposed conditions of use was considered safe for the environment. The additive Sangrovit® Extra had the potential to be efficacious in improving performance of weaned piglets at 0.600 mg sanguinarine/kg complete feed. This conclusion was extended to suckling piglets and extrapolated to other growing Suidae.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the proposed modification of the terms of the authorisation regarding the maximum inclusion level of a feed additive consisting of nonanoic acid for all pigs and poultry species. Nonanoic acid is currently authorised for use as a sensory additive (functional group: flavouring compounds) for all animal species at a recommended maximum content of 5 mg/kg complete feed. The applicant is requesting a modification of the authorisation to increase the recommended maximum content of the active substance from 5 to 100 mg/kg complete feed for all poultry and pig species. In support of the safety of the additive at the new proposed level, the applicant provided tolerance trials in the target species. The FEEDAP Panel concludes that nonanoic acid is safe for all growing poultry species and Suidae at 100 mg/kg feed. The Panel cannot conclude on the safety of the new proposed level (100 mg/kg complete feed) for laying hens, turkeys for breeding, minor poultry species for laying/breeding and reproductive Suidae. However, FEEDAP Panel considered that nonanoic acid is safe at 10 mg/kg complete feed in laying hens, turkeys for breeding, minor poultry species for laying/breeding and 20 mg/kg complete feed for reproductive Suidae. The use of the feed additive in animal nutrition under the conditions of use proposed is of no concern for the consumer and the environment. Due to the lack of data, the FEEDAP Panel cannot conclude on the potential of the additive to be a skin and eye irritant neither a dermal nor respiratory sensitiser. No further demonstration of efficacy is necessary.

RESUMO

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of Pediococcus acidilactici CNCM I-4622 as a zootechnical additive (functional group: physiological condition stabilisers) for all insects. The active agent used in the additive is already authorised for use in all animal species as a technological additive, and as a zootechnical additive in all Suidae species for fattening and for breeding, other than sows, all avian species, all fish species and all crustaceans. The active agent has been identified as a strain of P. acidilactici and consequently meets the qualifications required by the qualified presumption of safety (QPS) approach. The use of the additive is considered safe for all insect species, consumers and the environment. The additive is considered non-irritant to skin and eyes but a respiratory sensitiser. No conclusions can be drawn regarding its skin sensitisation potential. In the absence of adequate data, the FEEDAP Panel is not in the position to conclude on the efficacy of the additive as a physiological condition stabiliser for honeybees nor for all insect species.
