During meat production, a large amount of wastes are generated that consist of feces, tissue waste, blood, fat, bone, animal trimmings, intestinal content, and urine that can be a potential risk to humans and the environment. Low knowledge, negative attitude, and poor practice can lead to poor waste management, which is more severe in developing countries like Ethiopia. Thus, the current study aimed to assess the knowledge, attitudes, and practices of abattoir workers toward abattoir waste management in Eastern Ethiopia.
A cross-sectional study was conducted in Eastern Ethiopia' abattoirs from 1st to 30th of January, 2020. Two hundred and sixty-seven (n = 267) abattoir workers in 4 selected abattoirs (Haramaya University, Haramaya town, Harar town and Dire Dawa City administration) were interviewed using a pretested structured questionnaire. The data were analyzed using SPSS version 20 statistical package. Pearson's correlation was used to determine the strength between knowledge and attitude, knowledge and practice, and attitude and practice. A -value of .05 was considered as a cut-off point for statistical significance.
This study revealed that 203 (76%) of the respondents had less knowledge, 69 (26%) had a positive attitude and 43 (16%) of them had a good practice toward abattoir waste management. There was a statistically significant difference between socio-demographic characteristics (education, work experience, and salary) and knowledge, attitudes and practices of the study participants. This study found moderate positive correlations between knowledge and attitude [ = .404, = .013], weak positive correlations between knowledge and practice [ = .229, = .009], and strong positive correlations between attitude and practice [ = .717, = .023] of the abattoir workers toward waste management.
This study concluded that more than one-quarter, less than one-quarter, and about 3-quarter of the participants had less knowledge, negative attitude, and poor practice, respectively toward abattoir waste management. Therefore, regulatory bodies and other relevant industries must implement effective control measures that can be important to increase the knowledge, attitude, and practices of abattoir workers toward waste management.
在肉类生产过程中，会产生大量废物，包括粪便、组织废料、血液、脂肪、骨头、动物碎料、肠内容物和尿液，这些可能对人类和环境构成潜在风险。知识匮乏、态度消极和做法不当会导致废物管理不善，在埃塞俄比亚等发展中国家情况更为严重。因此，本研究旨在评估埃塞俄比亚东部屠宰场工人对屠宰场废物管理的知识、态度和做法。
2020年1月1日至30日在埃塞俄比亚东部的屠宰场进行了一项横断面研究。使用预先测试的结构化问卷对4个选定屠宰场（哈拉马亚大学、哈拉马亚镇、哈勒尔镇和德雷达瓦市行政当局）的267名屠宰场工人进行了访谈。使用SPSS 20版统计软件包对数据进行分析。采用Pearson相关性分析来确定知识与态度、知识与做法以及态度与做法之间的关联强度。P值<0.05被视为具有统计学意义的临界值。
本研究显示，203名（76%）受访者对屠宰场废物管理的知识较少，69名（26%）态度积极，其中43名（16%）做法良好。研究参与者的社会人口学特征（教育程度、工作经验和薪资）与知识、态度和做法之间存在统计学显著差异。本研究发现，屠宰场工人对废物管理的知识与态度之间存在中等程度的正相关[r = 0.404，P = 0.013]，知识与做法之间存在较弱的正相关[r = 0.229，P = 0.009]，态度与做法之间存在较强的正相关[r = 0.717，P = 0.023]。
本研究得出结论，分别有超过四分之一、不到四分之一和约四分之三的参与者对屠宰场废物管理知识较少、态度消极和做法不当。因此，监管机构和其他相关行业必须实施有效的控制措施，这对于提高屠宰场工人对废物管理的知识、态度和做法非常重要。
