Poultry Waste Management Practice in Kubwa
The study revealed poor poultry waste management in the district. Figure 4 shows the result of how poultry
waste was being managed in Kubwa. Indeed, all the farms visited did not observe good waste management
practices. Poultry wastes were left unattended for days. Some farms (25%) stored their waste in the pen
house where the birds live with the hope of selling them later as manure for crop farmers, while others (25%)
burnt them in the open. Yet few others (13%) spread them in the open to dry for manure. Most of the farms
(37%) either dumped their poultry waste in the drainage and water bodies especially during rainy season
when it was difficult to dry the waste for sale.The dangers of improper management of poultry waste have
been documented. According to Rahman, et al (2022), poultry waste was contributing to global climate
change by emitting greenhouse gases, such as nitrous oxide, CO2 , and CH4 , through microbial activity and
changes in temperature, pH, moisture, and oxygen concentrations. They confirmed that these air pollutants
could have a significant negative impact on both human and animal health, and may lead to a variety of
illnesses like nose discomfort, breathing issues, and coughing; while long-term exposure may lead to allergic
reactions and negative effects on life span. Nwanya, et al (2023) confirmed that poultry workers were at
greater risk of lung function impairment and airway obstructions due to exposure to air pollution in their
work environment. In their study, they observed that air quality in the selected poultry farms in Imo State
(South East Nigeria), was very poor due to poor poultry waste management.
In Kubwa, the practices of burning of poultry waste in the open and dumping in drainage and bodies of
surface water were very worrisome, with serious environmental health consequences. Open burning of waste
of any kind is said to be responsible for 11% of global black carbon emissions and contribute to 5-12% of
total global green-house gas emission (Climate Champions & Engineering X (2022). Indeed, Ramadan, et al
(2023) observed that open burning of waste served as a source of particulate matter and black carbon
possessed a greater greenhouse effect potential than CO2. The health consequences of air pollution as a
result of open waste burning are very serious. According to Seriki and Maag (2019), open burning of waste
was responsible for high level of unintended Persistent Organic Pollutants (uPOPs) in the environment,
capable of causing cancer, respiratory diseases, skin irritation, poor cognitive development in children, etc.
Akporube, et al (2023) observed that excessive production of waste from poultry farms and its improper
disposal has led to air pollution and contamination of surface and groundwater, which has become a major
public health concern to the society. According to them, improper disposal of poultry waste affects poultry
farmers, individuals residing close to the farms, and the environment. Therefore, as highlighted by Seriki and
Maag (2019) and Nwanya, et al (2023), there is obvious pending danger of health consequences due to air
pollution as poultry farms in Kubwa were very close to residential buildings.
Dumping of poultry waste in drainage and particularly in water bodies in Kubwa is another major concern.
This practice may lead to contamination of surface and ground water. Such has been the case elsewhere.
Interestingly, Taiwo, et al, (2013) found some heavy metals including Nitrate, Phosphate, Lead, Cadmium,
Zinc, etc, and high Coliform in body of water where poultry wastes were discharged in a study they
conducted in Abeokuta, Nigeria; even after the farm has been closed down before their study. The poor
management of poultry waste constitute nuisance and give room for microorganism and flies to act on them,
leading to decomposition and transfer of pathogens from one point to another. Also, there were cases of
contact of farm attendants with the wastes. Such practices may contribute significantly to the spread of
poultry related diseases.
Furthermore, these wastes can pose serious social, environmental and public health problems. Ordour from
exposed poultry remains can pollute ambient air quality. Decomposed and littered poultry wastes do release
gases such as ammonia, carbon dioxide, methane, hydrogen sulphide and nitrous oxide, especially when
exposed to water and heat, which may pollute the air. As noted, some of these gases may reach toxic levels if
adequate ventilation is not maintained within the farm house, (FAO, 2021). The various antibiotic remains
found in poultry waste could be possible triggers for antimicrobial resistance, which is yet a major public
health concern today (Bamidele, et al, 2022 and Abreu, et al, 2023).
