MILK Symposium review: Microbiological quality and safety of milk from farm to milk collection centers in Rwanda
The aim of this study was to generate knowledge on the most important milk quality and safety attributes, including somatic cell count (SCC), total bacterial count (TBC), Escherichia coli, Salmonella, and Brucella spp. antibodies and antibiotic residues in milk in the chain from farm to milk collection center (MCC) in Rwanda. In addition, we investigated farm and management factors associated with high TBC, SCC, and Salmonella counts. Raw milk was sampled at the farm and MCC levels. Milk samples were taken from dairy farms linked to 2 selected MCC in each of the 4 provinces in Rwanda. In total, 406 bulk milk samples from 406 farms and 32 bulk milk samples from 8 MCC were collected and analyzed. Farm milk average SCC varied between 180 Ă 103 and 920 Ă 103 cells/mL, whereas average SCC in milk samples at MCC varied between 170 Ă 103 and 1,700 Ă 103 cells/mL. The mean milk TBC of different farms per MCC varied between 1.1 Ă 106 and 1.6 Ă 107 cfu/mL, whereas in milk samples from different MCC, the mean TBC ranged between 5.3 Ă 105 and 2.4 Ă 108 cfu/mL. The high TBC in milk from MCC suggests proliferation or recontamination of milk by bacteria during transportation. Escherichia coli was detected in 35 of 385 farm milk samples and ranged between 5 cfu/mL and 1.1 Ă 104 cfu/mL, whereas in milk samples from the MCC, it was detected in 20 out 32 samples varying between 5 cfu/mL and 2.9 Ă 103 cfu/mL. Overall farm prevalence of Salmonella in milk samples was 14%, but no milk samples from MCC were positive for Salmonella. Five out of 22 bulk milk samples from different MCC were positive for Brucella spp. antibodies, but no Brucella antibodies were detected in milk samples from farms. The prevalence of antibiotic residues as detected by the Delvotest SP NT (DSM, Delft, the Netherlands) was low: 1.3% in farm milk samples and undetected in MCC milk samples. Lack of a separate milking area was associated with high TBC, whereas offering of supplemental feeds, keeping data of past diseases, and an unhygienic milking area were associated with high SCC. Lack of teat washing before milking was the only factor associated with Salmonella contamination of milk at the farm level. This study indicated high TBC and SCC of milk samples at the farm and MCC levels, which indicates both microbial contamination of milk and poor udder health in dairy cows. Presence of E. coli, Salmonella, and Brucella antibodies in milk was common, but finding antibiotic residues in milk was uncommon
Diseases and causes of death among alpacas in Sweden: a retrospective study
Background: Due to increasing popularity in Sweden during the last decade, alpacas are frequently encountered by practising veterinarians and pathologists. Knowledge regarding their health and diseases under Swedish conditions is, however, limited.
Objectives: To improve knowledge about the health of alpacas in Sweden by collecting information on diseases and health status. Design: A retrospective study was made of 93 necropsies conducted on alpacas in Sweden during the period 2001â2013. Setting Data were obtained from the two major veterinary pathology centres in Sweden. The alpacas were hobby or farm animals and they were submitted by veterinarians in local practices or at a national animal healthcare organisation.
Results: The digestive system was most frequently affected (29 per cent), with parasitic gastroenteritis (17 per cent) and hepatic disease being especially prevalent (15 per cent fascioliasis and 7 per cent hepatitis). Cardiovascular conditions (9 per cent), systemic diseases (7 per cent) and perinatal deaths were also common, including abortions (10 per cent) and fatal septicaemia (4 per cent). Wasting/emaciation was a frequent finding (26 per cent). Other diagnoses included dermatitis (8 per cent), diseases of the central nervous system (8 per cent), traumatic injuries (7 per cent), neoplasia (5 per cent), pneumonia (5 per cent) and nephritis (3 per cent).
Conclusions: This study identified areas of concern regarding diagnostic and pathological procedures, for which specific measures have been recommended. One particular cause for concern was the number of deaths from emaciation in weanling alpacas during late winter or early spring. For adult alpacas, infectious and noninfectious causes of death were approximately equally frequent. Many of the diseases were considered clinically acute but pathology often showed them to be chronic conditions that had eventually deteriorated and presented as acute cases in the late stages. This study revealed similarities in the health/disease status reported in other European countries and in North America. The results can be used by alpaca keepers and veterinary practitioners to improve management, diagnosis and treatment of alpacas
Armed conflict, insecurity, and attitudes toward women's and girls' reproductive autonomy in Nigeria
Background: Armed conflict and insecurity have been linked to deteriorations in reproductive health and rights globally. In Nigeria, armed violence has taken a significant toll on women's and girls' health and safety. However, knowledge is limited about how conflict shapes attitudes surrounding their ability to make autonomous decisions on relationships and childbearing. Drawing on a socioecological framework and terror management theory, we aimed to investigate the association between conflict, insecurity, and attitudes toward women's and girls' reproductive autonomy in Nigeria. Methods: We conducted a cross-sectional study using data from two sources: the World Values Survey (WVS) and the Uppsala Conflict Data Program-Georeferenced Event Dataset (UCDP-GED). Nationally representative data on attitudes of 559 men and 534 women was collected by WVS in 2017-2018. Linear probability models estimated the association between attitudes toward five dimensions of women and girl's reproductive autonomy (contraception, safe abortion, marital decisionmaking, delayed childbearing, early marriage), respondents' perceptions of neighborhood insecurity using WVS data, and geospatial measures of conflict exposure drawn from UCDP-GED. Results: Exposure to armed conflict and perceived neighborhood insecurity were associated with more supportive attitudes toward access to safe abortion among both men and women. Among women, conflict exposure was associated with higher support for contraception and the perception that early marriage can provide girls with security. Conflict -affected men were more likely to support a delay in girls' childbearing. Conclusion: Our findings suggest that conflict and insecurity pose a threat to, but also facilitate opportunities for, women's and girls' reproductive autonomy. Contraception, abortion, early marriage, and postponement or childbearing may be perceived as risk -aversion strategies in response to mortality threats, livelihood losses, and conflict -driven sexual violence. Our findings foreshadow changes in fertility and relationship patterns in conflict -affected Nigeria and highlight the need for health programming to ensure access to contraception and safe abortion services
Gender norms and womenâs empowerment as barriers to facility birth : A population-based cross-sectional study in 26 Nigerian states using the World Values Survey
Background Central and western Africa struggle with the worldâs lowest regional proportion of facility birth at 57%. The aim of the current study was to compare beliefs related to maternal health care services, science/technology, gender norms, and empowerment in states with high vs. low proportions of facility birth in Nigeria. Methods Face-to-face interviews were performed as part of a nationally representative survey in Nigeria using a new module to measure values and beliefs related to gender and sexual and reproductive health and rights collected as part the 2018 World Values Survey. We compared beliefs related to maternal health care services, science/technology, gender norms, and empowerment between Nigerian states with facility birth proportions > 50% vs. < 25% as presented in the 2018 Nigerian Demographic Health Survey report. Pearsonâs chi-squared test, the independent t-test, and univariable and multivariable logistic and linear regression were used for analyses. Results were also stratified by gender. Results Among the 1,273 participants interviewed, 653 resided in states with high and 360 resided in states with low proportions of facility birth. There were no significant differences between the groups in perceived safety of facility birth (96% vs. 94%) and confidence in antenatal care (91% vs 94%). However, in states with low proportions of facility birth, participants had higher confidence in traditional birth attendants (61% vs. 39%, adjusted odds ratio [aOR] 2.1, [1.5â2.8]), men were more often perceived as the ones deciding whether a woman should give birth at a clinic (56% vs. 29%, aOR 2.4 [1.8â3.3]), and participants experienced less freedom over their own lives (56% vs. 72%, aOR 0.56 [0.41â0.76]). Most differences in responses between men and women were not statistically significant. Conclusions In order to increase facility births in Nigeria and other similar contexts, transforming gender norms and increasing womenâs empowerment is key
Addressing the second ⏠R' in sexual and reproductive health and rights : why norms and values matter for development cooperation
Support for sexual and reproductive health and rights in Sub-Saharan Africa : a new index based on World Values Survey data
Background: Addressing attitudes is central to achieving sexual and reproductive health and rights (SRHR) and Agenda 2030. We aimed to develop a comprehensive index to measure attitudinal support for SRHR, expanding opportunities for global trend analyses and tailored interventions. Methods: We designed a new module capturing attitudes towards different dimensions of SRHR, collected via the nationally representative World Values Survey in Ethiopia, Kenya, and Zimbabwe during 2020-2021 (n = 3,711). We used exploratory factor analysis of 58 items to identify sub-scales and an overall index. Adjusted regression models were used to evaluate the index according to sociodemographic characteristics, stratified by country and sex. Results: A 23-item, five-factor solution was identified and used to construct sub-indices reflecting support for: (1) sexual and reproductive rights, (2) neighborhood sexual safety, (3) gender-equitable relationships, (4) equitable masculinity norms, and (5) SRHR interventions. These five sub-indices performed well across countries and socioeconomic subgroups and were combined into a comprehensive "SRHR Support Index", standardized on a 1-100 scale (mean = 39.19, SD = 15.27, Cronbach's alpha = 0.80) with higher values indicating more support for SRHR. Mean values were highest in Kenya (45.48, SD = 16.78) followed by Ethiopia (40.2, SD = 13.63), and lowest in Zimbabwe (32.65, SD = 13.77), with no differences by sex. Higher education and being single were associated with more support, except in Ethiopia. Younger age and urban residence correlated with more support among males only. Conclusion: The SRHR Support Index has the potential to broaden SRHR attitude research from a comprehensive perspective - addressing the need for a common measure to track progress over time
Coloniality and Whiteness in the Academy: Towards Decolonial Futures (Special Issue of Philosophy and Theory in Higher Education)
This special issue addresses the timely and under-theorised area in higher education, contributing to the knowledge and understanding about the complexities, paradoxes, tensions, and possibilities of designing decolonial futures in higher education. The idea for a special issue emerged during a series of Club Meet conversations within the Philosophy and Theory in Higher Education Society in October 2021.
Projecting âothernessâ on the non-white and the colonised, (Bhabha, 1994), the western university could be said to maintain and perpetuate colonial power structures, body-politics and geo-politics of knowledge-making. This can further reproduce designs for recolonising people, their Being and Becoming (Welikala, 2021), while suppressing and eradicating the knowledges of the âotherâ (Bhambra et al., 2018).
The recent surge in decolonising curriculum, pedagogy and research in higher education is reinforced by social movements and student activism. Focusing mainly on curriculum, pedagogy and research leaves the structural and systemic coloniality aside, encouraging the practice of embedding decolonisation predominantly within equality, diversity and inclusion (EDI) policies and practices. Subsequently, the notion of decolonisation is often conceptualised as a neutral, apolitical signifier/metaphor that can be used for a wide range of agendas within the neoliberal university, focusing on social justice (Tuck and Yang, 2012).
As guest co-editors, we argue that homogenising a wide range of experiences of oppression under the term âdecolonisationâ can mask decolonisation as philanthropic enterprise initiated by the âpowerfulâ global centres to offer voice to the âpowerlessâ, marginalised non-white groups (Cesaire, 2000). This ârefinedâ and comfortable approach to decolonising higher education focuses on limited areas of activity: diversifying the established knowledge/disciplinary cannons by introducing non-white authors; demonstrating interest in the acceptance of âalternativeâ epistemologies while focusing on the existing epistemic hegemonies; and increasing minority (BME) representation in operationalising EDI work that is led by the majority (white) groups. Rather than effectively addressing coloniality, such activities intensify the centrality of existing knowledge cannons while re-confirming the self-endorsed power of whiteness and the colonial imaginary within the academy (Maldonado-Torres, 2007).
The proliferating scholarship on decolonising education in the North, has seldom considered the pioneering, politically-informed perspectives of the global South and its theoretical underpinnings. The more radical decolonial turn pioneered by the scholars in the global South was focused on challenging the implications of modernity/coloniality and dismantling the colonial power hierarchies by transforming epistemic values and improving democracy in education (Mignolo, 2011). The absence of theoretical rigour and the lack of knowledge of the historicity of colonisation and coloniality has led towards a predominantly tokenistic approach to decoloniality in the academy in the global North
