Modification of the terms of authorisation regarding the maximum inclusion level of Maxiban G160 (narasin and nicarbazin) for chickens for fattening by EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

Following the 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 the proposed modification of the terms of the authorisation regarding the maximum inclusion level of Maxiban G160. The FEEDAP Panel cannot conclude on the safety of Maxiban G160 at a dose level of 70 + 70 mg/kg feed for the target species. The use of Maxiban% G160 in diets for chickens for fattening at the maximum proposed dose complies with the maximum residue levels (MRLs) in force of narasin and 4,4-ßdinitrocarbanilide (DNC) at 0 day withdrawal except for DNC in kidney which was slightly above the MRL. Compliance with DNC MRLs was seen in all tissues at 1 day withdrawal. Based on the available data, the FEEDAP Panel cannot conclude on the safety of Maxiban G160 for the environment due to the risk identified for the terrestrial organisms due to DNC. Moreover, the high persistence and hydrophobicity of DNC indicate that there might be a risk for bioaccumulation but the risk for secondary poisoning was not identified. The potential of DNC to accumulate in soil over the years should be investigated by monitoring in a field study. The FEEDAP Panel would not be in the position to conclude on the efficacy of Maxiban G160 in chickens for fattening based on the data provided for the dose of 40 + 40 mg narasin + nicarbazin/kg feed
Safety of Lactococcus lactis NCIMB 30160 as a feed additive for all animal species by EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

Following a request from European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety for the environment of the proposed modification of the terms of the authorisation regarding the formulation of the additive Lactococcus lactis NCIMB 30160. The applicant has proposed to modify the manufacturing process by adding polyethylene glycol (PEG 4000) in the list of potential cryoprotectants that can be used in the freeze-drying step, up to a maximum concentration of 0.025 mg PEG 4000/kg silage. The use of PEG 4000 as an excipient in formulations with Lactococcus lactis NCIMB 30160 would not change the previous conclusions regarding the safety for the target animals, consumers and users. No safety concerns are expected for the environment when PEG 4000 is used as a cryoprotectant in the additive Lactococcus lactis NCIMB 30160 up to a maximum concentration of 0.025 mg PEG 4000/kg silage
Safety for the environment of Monimax (monensin sodium and nicarbazin) for chickens for fattening, chickens reared for laying and for turkeys for fattening by EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)( )

1 edition published in 2019 in English and held by 1 WorldCat member library worldwide

Following a request from the European Commission, the Panel on Additives and Products or substances used in Animal Feed (FEEDAP Panel) was asked to deliver a scientific opinion on the safety and efficacy of the coccidiostat Monimax (monensin sodium and nicarbazin) when used in feed for turkeys or chickens for fattening. In previous assessments (2017, 2018), the FEEDAP Panel could not conclude on the safety of Monimax for the environment due to concerns on monensin sodium and 4,4%-dinitrocarbanilide (DNC, one of the moieties of nicarbazin). The applicant provided additional information that has been assessed. The use of monensin sodium from Monimax in complete feed for chickens for fattening, chickens reared for laying and turkeys for fattening poses no risk for the aquatic compartment, the terrestrial compartment or for sediment. The bioaccumulation potential of monensin in the environment is low. No concerns would arise for the 4,6%dimethylpyrimidin-2%ol (HDP) moiety of nicarbazin excreted from chickens for fattening, chickens reared for laying and turkeys fed Monimax. The use of DNC moiety of nicarbazin from Monimax in complete feed for chickens for fattening, chickens reared for laying and turkeys for fattening poses no risk for the aquatic compartment, the terrestrial compartments or for sediment. The bioaccumulation potential of DNC in the environment is low and the risk for secondary poisoning is not likely to occur
Numerical evaluation of bioaccumulation and depuration kinetics of PAHs in Mytilus galloprovincialis( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: Polycyclic aromatic hydrocarbons (PAHs) are important organic pollutants in the aquatic environment due to their persistence and bioaccumulation potential both in organisms and in sediments. Benzo(a)anthracene (BaA) and phenanthrene (PHE), which are in the priority pollutant list of the U.S. EPA (Environmental Protection Agency), are selected as model compounds of the present study. Bioaccumulation and depuration experiments with local Mediterranean mussel species, Mytilus galloprovincialis were used as the basis of the study. Mussels were selected as bioindicator organisms due to their broad geographic distribution, immobility and low enzyme activity. Bioaccumulation and depuration kinetics of selected PAHs in Mytilus galloprovincialis were described using first order kinetic equations in a three compartment model. The compartments were defined as: (1) biota (mussel), (2) surrounding environment (seawater), and (3) algae (Phaeodactylum tricornutum) as food source of the mussels. Experimental study had been performed for three different concentrations. Middle concentration of the experimental data was used as the model input in order to represent other high and low concentrations of selected PAHs. Correlations of the experiment and model data revealed that they are in good agreement. Accumulation and depuration trend of PAHs in mussels regarding also the durations can be estimated effectively with the present study. Thus, this study can be evaluated as a supportive tool for risk assessment in addition to monitoring studies. Graphical abstract: Highlights: Benzo(a)anthracene (BaA) and phenanthrene (PHE) were selected as representative PAHs (polycyclic aromatic hydrocarbons). Bioaccumulation and depuration of selected PAHs in mussels were evaluated numerically based on the experimental observations. Acceptable agreement was obtained between the experimental and numerical results. Developed model holds promise for estimating the uptake and depuration of PAHs for various concentrations and durations. Abstract : A numerical evaluation based on a comprehensive experimental study provides information about the uptake and depuration trends of PAHs in mussels for various concentrations
