“…The final selection of an animal to be sent to the killing bay occurs here. Dung, animal feeds, and urine are major wastes generated in the holding pen [ 24 ]. Slaughtering is a term used when the throat of an animal is slit and usually proceeds with bleeding.…”

“…Abattoirs are well designed structural facilities approved by relevant authority for the purpose of antemortem, hygienic slaughtering, evisceration and postmortem inspection of livestock (including cattle, goats, sheep, pigs and poultry) for wholesome meat production for public consumption (Alonge, 2005;Stevenson, 2013). The operational proce-dure in a standard abattoir (Figure 1) includes; the general inspection of animals in a lairage by a veterinarian for signs of diseases, humane slaughtering and evisceration, postmortem examination of carcass, removal of bones, dressing and cutting of carcasses either for storage in a designated refrigerator or immediate transportation using an enclosed motor vehicle for retail purposes (Mamhobu-Amadi et al, 2019). Besides serving as a central location where all the processes involved in the holding, slaughtering and preparation of food animals for public safety are carried out; the abattoirs also provide a veritable platform for animal disease surveillance through the instrumentality of veterinary examination of large and small animals (Food and Agricultural Organization, 2004;Morgan and Pinner, 2009).…”

The Coronavirus Disease-2019 (COVID-19) is an emerging zoonotic disease with global impact. Different intervention measures have been rolled out to flatten the curve, however the unhygienic conditions of abattoirs in Nigeria may be a perfect breeding ground for the novel coronavirus, hence could pose a threat to public health. The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was first reported among individuals who had either visited or had consumed food sold at the wet animal market in Wuhan, megacity of China in late December, 2019. The outbreak compelled China authority to close down all the wet animal markets in the Hubei province in an attempt to curb zoonotic transmission of the virus. Due to the unhygienic conditions of Nigerian abattoirs, butchers are more likely to come in contact with contaminated objects or surfaces and when they do, they may unknowingly infect themselves by touching their noses, mouth, or eyes with contaminated hands. Consequently, the virus could find its way into the respiratory tract to initiates an infection. Worst still, the lack of social distancing in the abattoirs can promote local transmission amongst butchers if some of them are infected and remain asymptomatic. These asymptomatic individuals can constitute a potential reservoir in the propagation and transmission of the virus within the abattoirs and in the community if they are not identified, isolated and treated. The current pandemic poses a threat of zoonotic transmission, hence, there is need for the Federal Government of Nigeria to make concerted effort in restoring sanitary in the abattoirs in order to forestall an outbreak of a virus that may be more deadly than SARS-CoV-2. This review therefore seeks to evaluate the growing concerns of the unhygienic conditions of abattoirs in Nigeria amidst the COVID-19 pandemic, the threats it poses to public health and the possible way forward.

Decoding Anaerobic Digestion: A Holistic Analysis of Biomass Waste Technology, Process Kinetics, and Operational Variables

et al. 2023

The continual generation and discharge of waste are currently considered two of the main environmental problems worldwide. There are several waste management options that can be applied, though anaerobic digestion (AD) process technology seems to be one of the best, most reliable, and feasible technological options that have attracted remarkable attention due to its benefits, including the generation of renewable energy in the form of biogas and biomethane. There is a large amount of literature available on AD; however, with the continuous, progressive, and innovative technological development and implementation, as well as the inclusion of increasingly complex systems, it is necessary to update current knowledge on AD process technologies, process variables and their role on AD performance, and the kinetic models that are most commonly used to describe the process-reaction kinetics. This paper, therefore, reviewed the AD process technologies for treating or processing organic biomass waste with regard to its classification, the mechanisms involved in the process, process variables that affect the performance, and the process kinetics. Gazing into the future, research studies on reduced MS-AD operational cost, integrated or hybrid AD-biorefinery technology, integrated or hybrid AD-thermochemical process, novel thermochemical reactor development, nutrient recovery from integrated AD-thermochemical process, and solid and liquid residual disposal techniques are more likely to receive increased attention for AD process technology of biomass wastes.
