- This study assessed seropositivity of Brucella infection in dairy animals and risk factors associated with it. The cross-sectional study used multi-stage, random sampling in the states of Bihar and Assam in India. In total, 740 dairy animals belonging to 534 households of 52 villages were covered under this study. Serological testing was conducted by indirect enzyme-linked immunosorbent assay (iELISA). Animal-level Brucella seropositivity was found to be 15.9% in Assam and 0.3% in Bihar. Seropositivity in urban areas (18.7%) of Assam was found to be higher than in rural areas (12.4%). Bihar was excluded from the risk factor analysis, as only one Brucella seropositive sample was detected in the state. A total of 30 variables were studied for assessing risk factors, of which 15 were selected for multivariable regression analyses following a systematic process. Finally, only three risk factors were identified as statistically significant. It was found that animals belonging to districts having smaller-sized herds were less likely (p < 0.001) to be Brucella seropositive than animals belonging to districts having larger-sized herds. Furthermore, the chance of being Brucella seropositive increased (p = 0.007) with the increase in age of dairy animals, but decreased (p = 0.072) with the adoption of artificial insemination (AI) for breeding. We speculated that the identified risk factors in Assam likely explained the reason behind lower Brucella seropositivity in Bihar, and therefore any future brucellosis control program should focus on addressing these risk factors.

Antibiotic Residues and Antimicrobial Resistant bacteria in the Poultry Value Chain of Two Indian States
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The poultry industry's rapid expansion has made it a significant global meat source, especially in India, which ranks as the eighth largest broiler meat producer. However, severe concerns have arisen over the increasing antibiotic resistance in low and middle-income countries, including India. This study systematically investigated the prevalence of Non-Typhoidal Salmonella (NTS) and Escherichia coli (E. coli) strains, along with their antimicrobial resistance (AMR) profiles, in poultry samples from Assam and Karnataka states in India. We found high prevalence of NTS (26%) and E. coli (53%) in various poultry samples, with substantial regional variations. Assam and Karnataka contribute differently to the overall NTS prevalence, with Karnataka bearing the highest burden (39% versus 14%). The presence of NTS and E. coli in treated water intended for watering poultry raises concerns about the effectiveness of water disinfection methods. Serovar analysis highlights the dominance of Typhimurium, Kentucky, Infantis and other serovars, some exhibiting multidrug resistance (MDR), including resistance to fluoroquinolones. The emergence of antibiotic-resistant strains, including carbapenem-resistant E. coli, presents a potential decline in treatment options. The study highlights the presence of MDR among NTS and stresses the importance of monitoring resistance profiles to devise effective antimicrobial strategies. The study underscores the necessity of collaborative efforts to combat AMR and ensure food safety, health, and wellbeing on a global scale.

Forskningsöversikt (refereegranskat)abstract
- Background: Foodborne diseases impose substantial public health burden and jeopardize socio-economic development worldwide. While accurate information on foodborne hazards is needed for informed decision in food safety interventions, such information is scarce in developing countries such as Burkina Faso. We conducted a systematic review and meta-analysis of studies reporting foodborne hazards in foods in Burkina Faso to describe the present knowledge of the situation.Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was used to conduct this review. Abstracts were searched in PubMed and CAB direct between 1 January 1990 to 30 September 2019. We used random-effects models to estimate pooled prevalence and I2 values to measure heterogeneity between studies.Results: 188 articles were identified, of which 14 are included in this review: 12 were on bacterial hazards (Salmonella, Campylobacter, Staphylococcus, E. coli, Shigella), three on fungal hazards and one on parasitic hazards (Toxoplasma gondii). The overall pooled prevalence of Salmonella spp. was 13% (95% CI: 8–21), the highest in lettuce: 50% (95% CI: 30–70) and the lowest in milk: 1.2% (95% CI: 0–5), demonstrating substantial variation among the studies (I2 = 85, 95% CI: 79–90%, p < 0.01). Campylobacter spp. was reported in chicken carcass, with 50% of the samples being positive. The overall pooled microbial load of Staphylococcus in the studied food samples was 3.2 log (95% CI: 2.8–3.6) CFU per g or ml of food, the highest in poultry samples: 4.5 log (95% CI: 2.8–6.2) CFU per g or ml of food. The overall pooled prevalence of Escherichia coli (E. coli) was 40% (95% CI: 29–51), the highest in beef intestines: 62% (95% CI: 22–91) and the lowest in dairy products: 31% (95% CI: 17–50), showing substantial variation across the studies (I2 = 86, 95% CI: 80–90%, p < 0.01).Conclusion: Our results showed widespread contamination of foods with foodborne hazards across various food value chains indicating poor hygienic handling of foods, raising consumers’ health risk due to foodborne illnesses from the foods. We recommend promotion of awareness creation in food safety and improved monitoring of hazards in food.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: Brucellosis is caused by bacteria from the genus Brucella which infect human and domestic animals as well as wildlife. The Maasai Mara National Reserve has vast populations of wild ruminants such as buffaloes and wildebeest which could contribute to the risk of brucellosis in livestock, and the surrounding pastoralist communities grazing cattle in and around the reserve may be exposed to a higher risk of zoonotic diseases like brucellosis due to the close contact with livestock. In this study, cattle from three villages at varying distance from the reserve, were screened for antibodies against Brucella abortus.RESULTS: In total, 12.44% of 225 sampled animals were seropositive, with more females (15%) infected than males (5%). Seroprevalence was higher in livestock closer to Maasai Mara with the cattle in the village Mara Rianta having an odds ratio of 7.03 compared to Endoinyo Narasha further away (95% CI 1.4-11.1, p = 0.003), suggesting that a closer contact with wildlife may increase the circulation of infectious diseases between livestock and wildlife. Symptoms consistent with brucellosis were reported to occur in both humans and animals, and we thus conclude that brucellosis may be an important problem, both for the health and the economy.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In order to meet growing energy demands, the world can no longer rely solely onconventional energy sources of the industrialization era. The renewable energy industry isgrowing fast to compensate for the energy deficit, while keeping the negative impact of thisgrowth on the environment to a minimum.The 2014 Marine Design Project client Blekinge Offshore AB has proposed a 700 windmillfarm in the Swedish waters of the Bay of Hanö. As part of this national-scaled project, thedesign and production of a vessel capable of transferring and installing the gravityfoundations as well as the windmills themselves needs to be designed.This report presents a special purpose vessel which uniquely combines principles of heavycargo lifting by ballast water management, winches and the ability to ground The Vesselduring loading of the cargo. The 7983 DWT vessel will shuttle between the coastal assemblysite and the wind farm site at a speed of 10 knots and facilitate the lifting, transporting andmounting of the foundations as well as the already assembled windmill towers. The Vesselitself is designed in such a way to have the smallest possible impact on the environment, asThe Baltic Sea is among the most tightly controlled regions in the world.The vessel is designed with special human factor considerations in order to cater for thesafety and comfort of the crew and the installation technicians, by means of sea keeping andaccommodation considerations. Despite the vessels size and the highly advanced operations itwill be performing, it only requires a crew size of 8 people.Also equipped with state of the art Dynamic Positioning technology, the vessel insuresaccuracy of operations while maintaining the shortest possible time schedule, thusminimizing operational costs.

- The decentralisation of Swedish healthcare closer to citizens has been slow. Drawing from empirical material of the reform prior and amidst the COVID-19 pandemic, this paper argues that the pandemic has disrupted the healthcare ecosystem. Consequently, citizen-centred collaborations have accelerated integration of resources (such as knowledge and skills) across organisational, hierarchical and professional borders. However, collaborations have been delimited to traditional healthcare providers, neglecting the resources of citizens and other actors to be used to improve service delivery. The pandemic has revealed strengths and weaknesses with the prevailing healthcare ecosystem that post-COVID-19 public management must address, both theoretically and practically. Theoretically, the paper contributes to the development of a public service logic, addressing both strengths and difficulties with the logic in turbulent times. Practically, the empirical descriptions contribute to improved understanding of public service delivery reform and how it is impacted during the pandemic. © 2021 The Authors.

Forskningsöversikt (refereegranskat)abstract
- Background: Foodborne disease (FBD) affects millions of people each year, posing a health burden similar to malaria, tuberculosis or HIV. A recent World Bank study estimated the productivity losses alone attributed to unsafe food within Africa at $20 billion in 2016, and the cost of treating these illnesses at an additional $3.5 billion. Ethiopia faces multiple food safety challenges due to lack of infrastructure and basic pre-requisites for food safety such as clean water and environment, washing facilities, compounded by limited implementation of food safety regulations, and a lack of incentives for producers to improve food safety. A consolidation of our understanding and evidence of the source, nature and scale of FBD in Ethiopia is needed to inform policy and future research. We performed a Systematic Literature Review (SLR) of publications on FBD occurrence in Ethiopia including hazard presence and impact.Method: The SLR followed Cochrane and PRISMA guidelines. We searched PubMed and CAB-Direct for relevant publications between 1990 and 2019 (inclusive). Observational studies and reviews were included. Two reviewers screened titles and abstracts, and retained publications were reviewed in full for quality and data extraction.Result: In total 128 articles met the inclusion criteria. Most articles focused on the identification of biological hazards in food. High levels of microbial contamination in different food value chains were often found in the small, ad hoc, observational studies that dominated the literature. Raw milk (22/128, 17.0%) and raw beef (21/128, 16.4%) were the most studied food products. Foodborne (FB) parasites were often found at higher rates in food than bacterial and viral pathogens, possibly due to differences in ease of identification. High levels of bacterial contamination on the hands of food handlers were widely reported. There were no reports on the incidence of human FBDs or resulting health and economic impacts.Conclusion: Our findings reflect existing concerns around food safety in Ethiopia. A lack of substantial, coordinated studies with robust methodologies means fundamental gaps remain in our knowledge of FBD in Ethiopia, particularly regarding FBD burden and impact. Greater investment in food safety is needed, with enhanced and coordinated research and interventions.

Tidskriftsartikel (refereegranskat)abstract
- Traditional food markets are age-old systems that primarily serve the food supply needs of society's less affluent sectors, often operating with minimal infrastructure. These markets are prevalent in low and middle-income countries. However, their hygienic conditions are frequently suboptimal, potentially fostering the emergence and spread of presumptive zoonotic diseases. The recent emergence of zoonotic or potentially zoonotic diseases and their possible links to traditional food markets under-score the need for focused attention on this overlooked issue. The socioeconomic characteristics of traditional food markets reveal that despite the risk of zoonotic pathogen spread, these markets play a crucial role for large segments of the population. These individuals rely on such markets for their livelihood, food, and nutrition. Therefore, a comprehensive set of measures ad-dressing various aspects of traditional food markets is necessary to manage and mitigate the risks of potential zoonotic disease emergence. In this article, we explore various facets of traditional food markets, paying special attention to the risks of zoonotic diseases that urgently require stakeholder attention. We also propose a new market design to prevent the risk of zoonotic spill-over and advocate for the development of a Market Hygiene Index for these markets.
