“…The higher seropositivity of Brucella infection among pregnant women showed by this study could be attributed in part due to the preference for raw foodstuffs like fresh milk, raw meat, and raw animal blood. Eating habits may expose an individual to Brucella infection if the consumed products from infected livestock are not properly prepared [12,18,21,22]. A substantial number of participants in the current study reported a preference for animal fresh milk (73.2%), preference for raw meat (24.3%) and preference for raw animal blood (55.6%).…”

Background: Brucellosis is a zoonotic disease transmitted to humans through contact with infected animals, animal products or consumption of infected dairy products. Brucella infection during pregnancy is of special interest due to association with adverse pregnancy outcomes. This study determined the seroprevalence and factors associated with Brucella infection among pregnant women around the human-wildlife-livestock interface area in Ngorongoro ecosystem, Northern Tanzania. Methods: A facility-based cross-sectional study was conducted between May and June 2018 at six health facilities that provide antenatal services. Pregnant women receiving antenatal care were invited to participate. A structured questionnaire was used to collect socio-demographic and obstetric characteristics in addition to behavior and practices related to the occurrence of human brucellosis. The presence of serum immunoglobulin against Brucella was determined using Rose Bengal Plate Test (RBPT). The positive samples were further assayed for the presence of IgG and IgM using The enzyme-linkedimmunosorbent assay. Bivariate analysis was conducted to determine the variables associated with Brucella seropositivity. Multivariable logistic regression analysis was performed to examine the factors independently associations with Brucella seropositivity after adjustment for other explanatory variables. Results: A total of 313 participants were enrolled in the study. The overall seroprevalence of Brucella infection was 10.9% (34/313) determined by Rose Bengal plate test. Of 34 positive individuals, 27(79.4%) and 8(23.5%) were positive in the ELISA specific for IgG and IgM Brucella antibodies respectively. Regular contact with manure (AOR 3.16, 95%CI 1.27-7.83) and preference for animal fresh milk (AOR 3.80, 95% CI 1.23-11.69), raw meat (AOR 2.58, 95% CI 1.14-5.81) and raw animal blood (AOR 2.71, 95% CI 1.15-6.35) increased the odds of being Brucella seropositive. Contact with the animal placenta were not associated with Brucella seropositivity after adjustment.

“…Despite the name, many other animals, including humans, are susceptible to infection with M. bovis and humans typically become infected following consumption of animal products contaminated with the bacterium or via close interaction with an infected animal (Muller et al., ; Perez‐Lago, Navarro, & Garcia de Viedma, ). The inhalation of contaminated aerosols usually results in pulmonary TB, whereas ingestion of contaminated products often results in an extra‐pulmonary infection (Hambolu, Freeman, & Taddese, ).…”

The natural fecundity of suids, great ability to adapt to new habitats and desire for local hunting opportunities leading to translocation of feral pigs to regions where they are not yet established have all been instrumental in the home range expansion of feral swine. Feral swine populations in the United States continue to expand, wreaking havoc on agricultural lands, further compromising threatened and endangered species, and posing a microbiological threat to humans, domestic livestock and companion animals. This manuscript thoroughly reviews zoonotic diseases of concern including brucellosis, bovine tuberculosis, leptospirosis, enteric pathogens, both Salmonella spp. and shiga toxin-producing Escherichia coli, and hepatitis E. These pathogens are not a comprehensive list of microbes that are capable of infecting both humans and feral swine, but rather have been selected as they are known to infect US feral swine, direct transmission between wild suids and humans has previously been documented, or they have been shown to be readily transmitted during processing or consumption of feral swine pork. Humans that interact directly or indirectly with feral swine are at much higher risk for the development of a number of zoonotic pathogens. Numerous case reports document transmission events from feral swine and wild boar to humans, and the resulting diseases may be mild and self-limiting, chronic or fatal. Individuals that interact with feral swine should take preventative measures to minimize the risk of disease transmission and all meat should be thoroughly cooked. Additionally, public health campaigns to increase knowledge of the risks associated with feral swine are imperative.

“…Through the FGDs it was noted that most people are at least involved in one practice placing them at risk of bTB or other zoonotic diseases such as brucellosis. The risky practices that are characteristic of pastoral communities particularly in sub-Saharan Africa included consumption of raw (soured milk) or undercooked meat, poor handling practices and absence of trained veterinary personnel during slaughtering of animals [29– 31]. Most of the participants indicated that they consumed boiled milk, but this practice might have been overstated due to awareness by the participants of the accepted practice.…”

21Bovine tuberculosis (bTB) is a disease of cattle that is transmitted through direct contact 22 with an infected animal or ingestion of contaminated food or water. This study seeks to 23 explore the local knowledge on the disease and establish the risk practices that lead to 24 its transmission to cattle and humans (zoonotic TB) in a traditional livestock farming 25 community with a history of bTB diagnosis in cattle and wildlife. Information was 26 collected using a qualitative approach of Focus Group Discussions (FGDs) targeting 27 household members of livestock farmers that owned either bTB infected or uninfected 28 herds. We conducted fourteen FGDs (150 individuals) across four dip tanks that 29 included the following categories of participants from cattle owning households: heads 30 of households, cattle keepers, dip tank committee members and women. The qualitative 31 data was managed using NVivo Version 12 Pro ® software. Social and cultural practices 32 were identified as major risky practices for bTB transmission to people, such as the 33 consumption of undercooked meat, consumption of soured /raw milk and lack of 34 protective measures during slaughtering of cattle. The acceptance of animals into a 35 herd without bTB pre-movement testing following traditional practices (e.g. lobola, 'bride 36 price', the temporary introduction of a bull for 'breeding'), the sharing of grazing and 37 watering points amongst the herds and with wildlife were identified as risky practices for 38 bTB transmission to cattle. Overall, knowledge of bTB in cattle and modes of 39 transmission to people and livestock was found to be high. However, the community 40 was still involved in risky practices that expose people and cattle to bovine TB. An inter-41 disciplinary 'One Health' approach that engages the community is recommended, to 42 provide locally relevant interventions that allows the community to keep their traditional 43 3 practices and socio-economic systems whilst avoiding disease transmission to cattle 44 and people. 45 Author summary 46 Bovine tuberculosis (bTB) is a respiratory disease of cattle that is transmitted to 47 other animals as well as humans (zoonotic TB) through direct contact with infected 48 animals, and consumption of contaminated food (animal products) or water. The study 49 explains the complexities of human-animal relations, reflects on how people understand 50 and conceptualize risk of bovine tuberculosis (bTB) in an endemic area considering the 51 economic value of livestock keeping as well as social and cultural practices of 52 importance to the community. The results of this study identified socio-cultural practices 53 that involved consumption of raw or undercooked animal products and handling of 54 infected animal products during animal slaughter as major risky practices for bTB 55 transmission to people. Introduction of animals into a herd without bTB testing for socio-56 cultural purposes and sharing of resources amongst the communal herd and with 57 wildlife were identified as risky p...
