Abattoir characteristics and seroprevalence of bovine brucellosis in cattle slaughtered at Bodija Municipal Abattoir, Ibadan, Nigeria

Abstract

Brucella abortus infection in humans in Nigeria has been recorded as a cause of febrile disease. In Nigeria, the transhumance (Fulani nomadic) husbandry system is the most common cattle farming system with about 95% of all the country's cattle population produced under this husbandry system. About 75% of all slaughtered cattle are processed in government-approved abattoirs. In view of the aforementioned, this abattoir can give a fair representation for a surveillance study of the Nigerian cattle population. 220 cattle were selected on arrival using systematic random sampling from a total slaughter population of 17,912 cattle, and were chosen over a 10-week period. Sixty-three percent (63.2%) of all slaughtered animals were cows, and only 4% were under 18 months (two-tooth). The indigenous breeds predominated and individual seroprevalence of B. abortus was estimated at 5.45% (n=12) using the Rose Bengal plate test. Currently, no safety measures is in place for abattoir workers and pre-slaughter monitoring for positive animals is lacking. Certain measures were suggested to reduce the zoonotic risk of human brucellosis from the slaughter process.

A review on the state of abattoirs in Nigeria during COVID-19 pandemic era: Potential threats and public health interventions

“…The conditions of abattoirs in Nigeria are best imagined than described. The ugly situation is the same across the six (6) geo-political zones of the country (Figure 3) including: North East (Jalingo Metropolitan abattoir, Damaturu abattoir in Yobe), North-West (Malumfashi abattoir in Katsina, Maiyanka abattoir in Kano, Zangon Shanu abattoir in Kaduna and Kara abattoir in Sokoto), North Central (Jos abattoir, Wurukum abattoir in Benue, Lapai slaughter house in Niger, Wurukum abattoir in Benue, Ipata slaughter house in Kwara, Deidei and Karu abattoirs in Abuja), South-East (Afikpo abattoir in Ebonyi, Nsukka abattoir in Enugu, Afor-Ajala Mbaise abattoir in Imo), South-West (Oko Oba abattoir in Lagos, municipal abattoir in Bodija, Ibadan) and South-South (Trans-Amadi abattoir in Port-Harcourt, Ikpoba abattoir and Afuze slaughter house in Edo) (Adeyemo, 2002;Nwanta, et al, 2008 and2010;Lawan et al, 2013;Bwala et al, 2015;Gali et al, 2020). Aniebo et al (2009) reported the generation of several thousand tons of gut contents, blood, and waste tissues discharged directly into the environment from a local abattoir in North-East, Nigeria.…”

Prevalence of Echinococcus granulosus sensu lato in Owned Dogs in Lagos State, Nigeria

“…These findings attest to the public health challenge of CE in humans and animals in Nigeria. For the concurrent presence of one of the largest slaughter facilities in Nigeria, with daily throughput of about 3000 livestock [19,20] and of other conditions regarded as risk factors for human CE, we focused our investigation on the Lagos State area. Considering the limited amount of data on the epidemiology of E. granulosus s.l.…”

Sero-prevalence of bovine brucellosis in the Bojanala Region, North West Province, South Africa 2009–2013

“…It is easily confused with malaria and influenza (Bamaiyi 2016;Doganay & Aygen 2003). Brucellosis in humans is under-reported because of vague clinical symptoms, difficulties with laboratory diagnosis and the medical profession's lack of knowledge about the disease (Bwala et al 2015;Dean et al 2012;Franco et al 2007;Frean et al 2018;Ibironke et al 2008;Mukhtar & Kokab 2008). The World Health Organization considers it a neglected zoonosis, because it is seldom prioritised by national and international health systems (World Health Organization 2006).…”

“…The World Health Organization considers it a neglected zoonosis, because it is seldom prioritised by national and international health systems (World Health Organization 2006). In Africa, bovine brucellosis can have serious economic impacts, resulting from loss of work or income due to illness and disability (Bwala et al 2015). This impact on human health can be quantified using the disability-adjusted life year, or DALY (Marcotty et al 2009).…”

“…Occupations at risk include farmers, farm-workers, butchers, abattoir workers, dairy personnel, veterinarians, laboratory technicians and animal health officers (Bamaiyi 2016;Bwala et al 2015;Marcotty et al 2009). Consumers can be infected by unpasteurised dairy products including butter, milk, cheese and yoghurt (Hesterberg et al 2008).…”
