Abstract
Background: Campylobacter is an important water- and food-borne pathogen with notable genetic similarity among strains isolated from humans, animals, and environmental sources. This systematic review and meta- analysis synthesized available evidence on the prevalence, antimicrobial resistance, and associated risk factors of Campylobacter in humans, animals, and the environment in Ethiopia. Methods: Articles published from 1997 to 2024 were systematically searched and retrieved from PubMed, Science Direct, Web of Science, and Google Scholar. The review was conducted in accordance with the PRISMA guidelines, and data from eligible articles were extracted using a standardized data extraction template. Heterogeneity was evaluated using Cochran’s Q statistic, the I² statistic, and Egger’s test for small-study effects. Data extraction and analysis were conducted using Microsoft Excel and Stata 14. Results: Of the 11,573 samples analyzed across 26 studies, 3204 were positive for Campylobacter, yielding a pooled prevalence of 19.9 %. The highest prevalence was observed in environmental samples (33.4 %), followed by humans (31.4 %) and animals (24 %). Regionally, Oromia showed the highest prevalence (30.4 %), while Addis Ababa and Tigray reported the lowest (11.0 %). Cephalothin and ampicillin exhibited the highest antimicrobial resistance (100 %), whereas gentamicin showed the lowest (7.1 %). Campylobacter jejuni and Campylobacter coli were the most frequently identified species and demonstrated the highest resistance levels. Major risk factors for campylobacteriosis included frequent animal contact, consumption of undercooked or contaminated food and water, and low parental education levels among affected children. Conclusion: This study highlights the distribution and increasing prevalence of Campylobacter and associated antimicrobial resistance within a One Health framework. Future research should encompass wider geographic coverage and include diverse sources such as poultry, companion animals, vegetables, and wastewater to generate more comprehensive epidemiological data. Such efforts will help address existing knowledge gaps and support the development of targeted interventions to reduce foodborne infections and mitigate antimicrobial resistance.

Considering the most recent technical and scientific information available to the experts, the Group is requested: (5) to agree on the criteria for evaluation of substances for cleaning and disinfection to be applied to all fields of organic production where the use of such agents is necessary to maintain a high level of food hygiene. (6) to make a proposal for a negative list of substances with unwanted properties based on the above defined criteria. (7) to carry on some worked examples of evaluation of prioritized dossiers submitted by the Member States on products for cleaning and disinfection based on the criteria agreed: i. Hydrogen peroxide (DK) ii. Sodium percarbonate (hydrogen peroxide released from sodium percarbonate, DK) iii. Sodium hydroxide (NL) iv. Glutaraldehyde (SE) v. Chlorine dioxide (NO) vi. Calcium hypochlorite (FR) vii. Peracetic acid (FR) viii. Formic acid (FR) ix. Sodium hypochlorite (FR) x. Iodophors (FR) xi. Dipotassium peroxodisulfate + potassium peroxomonosulfate (SE) xii. Fatty acid potassium salt (SE) xiii. Methane sulfonic acid (probably GER, the request was made by BASF Ludwigshafen) (8) to schedule the work for evaluating the rest of the substances on the Commission priority list. For the preparation of its report the Group was invited to examine technical dossiers provided to the Commission by the Member States and suggest amendments to the Annex IV to the Regulation (EU) 2021/1165.

The Expert Group for Technical Advice on Organic Production (EGTOP, thereafter called ‘the Group’) was asked to prepare a technical advice about the applicability of detergents (referred to in the organic legislation as ‘products for cleaning’) and biocidal products (referred to in the organic legislation as ‘products for disinfection’) in organic production. The use of biocidal products and detergents in organic production must be compliant with the Biocidal Products Regulation (EU) No 528/2012 and the Regulation (EC) No 648/2004 on Detergents.

This report responds to the European Commission’s request for technical advice from EGTOP on the compliance of innovative building systems for pigs with organic farming principles and regulations, particularly those outlined in Regulation (EU) 2018/848 and implementing Regulation (EU) 2020/464 . These systems integrate indoor barns with covered outdoor areas but generally lack direct access to open air areas, preferable pasture. The Group assessed these systems in light of organic principles, animal welfare standards, environmental impacts, structural design, biosecurity risks, farmer working conditions, and consumer expectations. The assessment considered scientific literature, existing EU legislation, and the core values of organic production: health, ecology, fairness, and care. The Group acknowledges that these innovative modular systems may offer improvements in thermal comfort, increased outdoor area, manure management, and labor efficiency in confined conditions. In the system under assessment, the available indoor surface appears reduced compared to the requirements outlined in organic standards (Regulation (EU) 2020/464, Articles 11 and 12), while outdoor access would not be guaranteed during adverse weather conditions. The limited indoor area risks compromising animal welfare, falling below the minimum standards of organic production, as animals may be left without sufficient space or opportunities to express natural behaviours under such circumstances.

This study proposes a new workflow for crop growth evaluation and yield calibration in the Soil and Water Assessment Tool Plus (SWAT+) model and evaluates its impact on simulated hydrological and biogeochemical processes. The workflow was applied for ten small agricultural catchments in Europe. A detailed demonstration is provided for the German catchment, Schwarzer Schöps. The workflow proved effective across all catchments, improving yield calibration from an initial R2 of 0.5–0.84. The results show that evapotranspiration and soil moisture were only moderately affected by crop calibration in three catchments (Belgium, Czech Republic and Norway) and negligibly changed in the remaining ones. Sediment and nutrient balance were affected more strongly: sediment, nitrogen and phosphorus loss change reached 82 % (Norway), 16 % and 20 % (Czech Republic), respectively. The proposed workflow is a valuable tool for improving the accuracy of SWAT + simulations and can be used to support decision-making in environmental management.

Bakgrunn: Overvåking av karbon i skogjord gjennomføres i mange land, noe som har resultert i omfattende nasjonale datasett, også i tilfelle hvor landene har felles grenser og i stor utstrekning lignende eller tilsvarende skogs- og jordtyper. Mulighet: Internasjonalt samarbeid om data og feltmetoder kan legge til rette for integrasjon av datasett og sammenligning av overvåkingsdata til støtte for utvikling av internasjonal politikk i et multinasjonalt fremfor et nasjonalt perspektiv. Utfordring: Variasjoner i overvåkingsmetodikk mellom land må håndteres for å kunne gjennomføre en effektiv syntese av data om karbon i skogjord. Tilnærming: Hvert land har utviklet sitt eget overvåkingsprogram for å møte spesifikke og nasjonale miljømessige og institusjonelle behov, noe som har ført til omfattende datasett på nasjonalt nivå. Harmonisering kan bidra til å realisere det fulle potensialet i disse nasjonale datasettene gjennom utvikling av internasjonale referansedefinisjoner. En tilnærming med utgangspunkt i harmonisering tillater nasjonal tilpasning, samtidig med at data kan brukes i en internasjonal kontekst, i kontrast til standardisering og en «én størrelse passer alle»-tilnærming.
Abstract
Studien undersøker hvordan vegetasjonsdekke (NDVI) og overflaterefleksjon (albedo) varierer gjennom året i norske utmarksområder som er beitet og ubeitet. Utmarkene har stor betydning for beitebruk, biologisk mangfold og karbonlagring, men endringer i landbruk og redusert beitepress påvirker vegetasjonen og kan ha klimakonsekvenser. Analysen bygger på satellittdata fra 18 lokaliteter i perioden 2019–2023. Resultatene viser tydelige sesongmønstre: NDVI er lav om vinteren og høy om sommeren, mens albedo er høy i snødekte perioder og lav når vegetasjon dominerer. Det ble ikke funnet signifikante forskjeller mellom beitede og ubeitede områder samlet sett, selv om enkelte lokaliteter viste små variasjoner. Dette tyder på at sesong og fenologi har større betydning enn beite, og at metodiske begrensninger – særlig grov oppløsning i albedodata – kan maskere lokale effekter. Studien anbefaler bruk av høyoppløselige data og mer avanserte metoder for å bedre forstå klimaeffektene av endret beitebruk.

VKM has assessed animal welfare during stunning and killing of farmed fish in Norway. This report gives an overview of species differences which have significance for the slaughter procedures. The general conclusion is that there is a general lack of scientific documentation to meet the legislation stating that fish must remain unconscious after stunning until death by exsanguination. VKM also finds a risk of reduced animal welfare due to lack of documentation of the time from gill or cardiac cutting to cessation of brain activity. Further research and documentation are needed to understand how different behavioural and physical measurements conducted at the slaughter facility, correspond with the electroencephalogram (EEG) measurements of unconsciousness.
