Animal production - Climate impact - Disability-adjusted life year (DALY) - Environmental impact - Livestock farming
Observed multiple adverse effects of livestock production have led to increasing calls for more sustainable livestock production. Quantitative analysis of adverse effects, which can guide public debate and policy development in this area, is limited and generally scattered across environmental, human health, and other science domains. The aim of this study was to bring together and, where possible, quantify and aggregate the effects of national-scale livestock production on 17 impact categories, ranging from impacts of particulate matter, emerging infectious diseases and odor annoyance to airborne nitrogen deposition on terrestrial nature areas and greenhouse gas emissions. Effects were estimated and scaled to total Dutch livestock production, with system boundaries including feed production, manure management and transport, but excluding slaughtering, retail and consumption. Effects were expressed using eight indicators that directly express Impact in the sense of the Drivers-Pressures-State-Impact-Response framework, while the remaining 14 express Pressures or States. Results show that livestock production may contribute both positively and negatively to human health with a human disease burden (expressed in disability-adjusted life years) of up to 4% for three different health effects: those related to particulate matter, zoonoses, and occupational accidents. The contribution to environmental impact ranges from 2% for consumptive water use in the Netherlands to 95% for phosphorus transfer to soils, and extends beyond Dutch borders. While some aggregation across impact categories was possible, notably for burden of disease estimates, further aggregation of disparate indicators would require normative value judgement. Despite difficulty of aggregation, the assessment shows that impacts receive a different contribution of different animal sectors. While some of our results are country-specific, the overall approach is generic and can be adapted and tuned according to specific contexts and information needs in other regions, to allow informed decision making across a broad range of impact categories.

Chemical mixtures - Combined exposure - Environmental chemicals - Mixture risk assessment - Risk management
The number of anthropogenic chemicals, manufactured, by-products, metabolites and abiotically formed transformation products, counts to hundreds of thousands, at present. Thus, humans and wildlife are exposed to complex mixtures, never one chemical at a time and rarely with only one dominating effect. Hence there is an urgent need to develop strategies on how exposure to multiple hazardous chemicals and the combination of their effects can be assessed. A workshop, “Advancing the Assessment of Chemical Mixtures and their Risks for Human Health and the Environment” was organized in May 2018 together with Joint Research Center in Ispra, EU-funded research projects and Commission Services and relevant EU agencies. This forum for researchers and policy-makers was created to discuss and identify gaps in risk assessment and governance of chemical mixtures as well as to discuss state of the art science and future research needs. Based on the presentations and discussions at this workshop we want to bring forward the following Key Messages: • We are at a turning point: multiple exposures and their combined effects require better management to protect public health and the environment from hazardous chemical mixtures. • Regulatory initiatives should be launched to investigate the opportunities for all relevant regulatory frameworks to include prospective mixture risk assessment and consider combined exposures to (real-life) chemical mixtures to humans and wildlife, across sectors. • Precautionary approaches and intermediate measures (e.g. Mixture Assessment Factor) can already be applied, although, definitive mixture risk assessments cannot be routinely conducted due to significant knowledge and data gaps. • A European strategy needs to be set, through stakeholder engagement, for the governance of combined exposure to multiple chemicals and mixtures. The strategy would include research aimed at scientific advancement in mechanistic understanding and modelling techniques, as well as research to address regulatory and policy needs. Without such a clear strategy, specific objectives and common priorities, research, and policies to address mixtures will likely remain scattered and insufficient.

In the Netherlands, an association was found between the prevalence of pneumonia and living near goat and poultry farms in 2007-2013. This association then led to regulatory decisions to restrict the building of new goat farms and to reduce emissions of poultry farms. Confirmation of these results, however, is required because the period of previous analyses overlapped a Q-fever epidemic in 2007-2010. To confirm the association, we performed a population-based study during 2014-2016 based on general practitioner (GP) data. Electronic medical records of 90,183 persons were used to analyze the association between pneumonia and the population living in the proximity (within 500-2000 m distance) of goat and poultry farms. Data were analyzed with three types of logistic regression (with and without GP practice as a random intercept and with stratified analyses per GP practice) and a kernel model to discern the influence of different statistical methods on the outcomes. In all regression analyses involving adults, a statistically significant association between pneumonia and residence within 500 meters of goat farms was found (odds ratio [OR] range over all analyses types: 1.33-1.60), with a decreasing OR for increasing distances. In kernel analyses (including all ages), a population-attributable risk between 6.0 and 7.8% was found for a distance of 2000 meters in 2014-2016. The associations were consistent across all years and robust for mutual adjustment for proximity to other animals and for several other sensitivity analyses. However, associations with proximity to poultry farms are not supported by the present study. As the causes of the elevated pneumonia incidence in persons living close to goat farms remain unknown, further research into potential mechanisms is required for adequate prevention.

|Integrated risk assessment of changing animal production systems in the Netherlands
Post, P.J. ; Hogerwerf, Lenny ; Bokkers, E.A.M. ; Posthuma, Leo ; Boer, I.J.M. de; Lebret, E. - \ 2017
Considerable momentum is building to change existing practices in the Dutch livestock sector. With approximately 14 goats, 123 cows, 374 pigs, 3196 chickens, and 501 humans per km2, animal production, residential areas and natural areas compete for space. Evidence of substantial impacts on human health and ecosystem integrity are mounting, suggesting non-sustainable developments. Programs to foster sustainability run for some years but recently the Dutch government was advised to increase the pace. The evidence of impacts are, however, scattered over different domains, and the existence of (policy) ‘silos’ prevent an integrated solution to current impacts. This study aims to provide a first attempt to describe the current impacts of the Dutch livestock sector, including infectious diseases spread and emerging zoonosis risks, carbon and nitrogen emissions, particulate matter and endotoxin emissions, antimicrobial resistance and odors. We consider this first overview as a baseline for comparison with future scenarios for changing animal production systems.

Biological processes underlie all livestock traits, including post-mortem meat quality traits. Biomarkers are molecular components of the biological processes showing differential expression associated with the phenotype of the trait. The phenotypes of the meat quality traits are determined by the animal's genotype interacting with the environment affecting the expression of the genome. The

The data was collected in the field from 15 April to 15 May (from 27 April to 15 May for the Voorstonden location). The first column shows the 7 sites (from 1 to 7) used in the models as random effects. Site 1 corresponds to a location called ‘Lebret’s Hoeve’, site 2 to ‘Voorstonden’, site 3 to ‘Radio Kootwijk’, and site 7 to ‘Hijkerveld’. Sites 4 and 5 are adjacent spatially and correspond to a location called ‘ASK Doornspijk’. Finally, site 6 consists of two sites merged together because they overlap in a location called ‘Klaterweg’. The onsets (column 7) have therefore been obtained from the mean onsets in the two former sites for each light treatment on each day. The second column shows the 3 levels of 'Treatment', which represents the transects where the data has been collected (green, red, or white light transect). The third column shows the 'Formal date', i.e., the date at which the bird was singing (in calendar days). The fourth column shows the (relative) ‘date', which is the date relative to 15 April (0 = 15 April), and which has been used in the models as a random slope. The fifth column shows the 'onset relative to control'. This variable is calculated for each species, at each site and on each day, as the difference (in min) in the onset of dawn song between each light treatment (red/green/white) and the dark control. The sixth and last column shows the 'species' for which the onset is shown (14 levels, vernacular names shown).

Stikstof is noodzakelijk voor alle vormen van leven. Het is bijvoorbeeld een belangrijke bouwsteen van eiwitten. Planten, dieren en mensen nemen het op als reactief stikstof. Dat moet uit stikstof in de buitenlucht worden gevormd. In de natuur wordt reactief stikstof slechts op beperkte schaal gevormd, hoofdzakelijk door micro-organismen. De kunstmatige vorming van reactief stikstof werd een eeuw geleden mogelijk gemaakt door de uitvinding van een proces voor de synthese van ammoniak. Deze uitvinding legde de basis voor de fabricage van kunstmest. Daarmee werd een enorme toename van de voedselproductie per hectare grond mogelijk. Naast ammoniak vallen onder reactief stikstof nog vele stikstof bevattende verbindingen, waaronder ammonium- en nitraatzouten. Rijke werelddelen en landen, waaronder Europa, en zeker Nederland, hebben te maken met een teveel aan reactief stikstof in het milieu. Dit leidt tot aantasting van dit milieu en van de volksgezondheid. De overmaat aan reactief stikstof heeft twee belangrijke oorzaken: de landbouw en veehouderij, en de verbranding van fossiele brandstoffen. De Gezondheidsraad heeft zich over de mogelijke effecten van reactief stikstof op de Nederlandse volksgezondheid gebogen. Een commissie van de raad, de Commissie Signalering Gezondheid en milieu, heeft beoordeeld in hoeverre de volksgezondheid gebaat is bij het terugdringen van de hoeveelheid reactief stikstof in ons land.

A total of 120 crossbred [synthetic line x (Large White x Landrace)] pigs (castrated males and females) were used to evaluate the influence of rearing conditions for growing-finishing pigs on growth performance, carcass, stress reactions at slaughter, and meat eating quality. At approximately 35 kg of live weight (LW), littermates were allocated to either a conventional (fully slatted floor, 0.65 m2/pig, considered as control, CON) or an alternative (sawdust bedding with free access to an outdoor area, 2.4 m2/pig, OUT) system, until slaughter at approximately 110 kg of LW. Pigs had free access to standard growing and finishing diets. The trials were conducted in spring, summer, and winter, with each season involving 2 pens of 10 pigs in each system. Compared with the CON, the OUT pigs exhibited a greater growth rate (+10%, P <0.001) due to their greater feed intake (+0.23 kg/d, P <0.01), resulting in a greater body weight at slaughter (+7 kg, P <0.001). The OUT pigs had thicker backfat (+2.4 mm, P <0.01) and lower lean meat content (¿ 2.0% points, P <0.001) than the CON pigs. The OUT system did not (P > 0.10) influence the behavioral activities of pigs during lairage at the slaughterhouse, or the urinary levels of catecholamines and cortisol, and plasma levels of ACTH, cortisol, lactate, creatine kinase, and FFA immediately after slaughter. The OUT pigs had similar (P > 0.10) pH values 30 min postmortem (pH1) in the LM, biceps femoris (BF), and semimembranosus (SM) muscles, similar ultimate pH (pHu) in LM, but lower pHu in SM (¿ 0.07 unit, P <0.001) and in BF (¿ 0.03 unit, P = 0.029). Despite nonsignificant effects of production system on stress reactions at slaughter, assessed by urine and plasma indicators and muscle metabolism at 30 min postmortem, meat from OUT pigs had more LM drip loss after 2 (+1.0%, P = 0.003) and 4 (+1.1%, P = 0.010) d than did meat from the CON pigs. The OUT system slightly increased meat yellowness (b* value) in the LM (+0.7 unit, P = 0.001), BF (+0.5 unit, P = 0.014), and SM (+0.5, unit P = 0.041), whereas redness (a*) and lightness (L*) of the 3 muscles were unaffected (P > 0.07). Intramuscular fat content was greater in the LM (+17%, P = 0.001), BF (+14%, P = 0.004), and SM (+17%, P = 0.003) of the OUT pigs. Outdoor rearing during summer and winter improved meat juiciness, whereas odor, flavor, and tenderness were unaffected (P > 0.10). Influence of rearing conditions on all the other traits studied did not depend on the season.
