Knowledge, Attitude, and Practice of Abattoir Workers Toward Abattoirs Waste Management in Eastern Ethiopia

BACKGROUND

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.

METHODS

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 P-value of .05 was considered as a cut-off point for statistical significance.

RESULTS

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 [r = .404, P = .013], weak positive correlations between knowledge and practice [r = .229, P = .009], and strong positive correlations between attitude and practice [r = .717, P = .023] of the abattoir workers toward waste management.

CONCLUSION

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.

Prevalence of bovine brucellosis in slaughtered cattle and barriers to better protection of abattoir workers in Ibadan, South-Western Nigeria

INTRODUCTION

Brucellosis is a neglected zoonosis of public health importance. This study was conducted to determine the prevalence and risk factors of brucellosis among slaughtered cattle as well as challenges to the protection of abattoir workers in Nigeria.

METHODS

A slaughterhouse study was conducted in a major abattoir in Ibadan from March to August, 2013. To diagnose brucellosis, serum samples from 1,241 slaughtered cattle were tested using Rose-Bengal test (RBT) and competitive enzyme-linked immunosorbent assay (cELISA); again, 57 milk samples were tested with milk ring test (MRT) and indirect ELISA (iELISA). Furthermore, a survey on the usage of personal protective equipment (PPE) and challenges to its use by abattoir workers was done. Data were analysed using Stata 12.

RESULTS

Seroprevalence by RBT was 7.8%; 77.3% (75/97) of these were corroborated by cELISA. Prevalence in milk samples by MRT and indirect ELISA were 33.3% and 3.5%, respectively. Sex (OR: 2.5; 95%CI:1.3-4.5) was the factor significantly associated with Brucella seropositivity. None of the abattoir workers used standard protective overalls; while, 99.6% of the meat handlers and 84.1% of the butchers worked barefoot. Most of the workers (75.7%) wore no protective gloves. The respondents agreed that provision of free PPE and sanctions against non-users would encourage its use.

CONCLUSION

Our findings indicate moderate prevalence (7.8%) of bovine brucellosis with sex of cattle being a risk factor. A notable barrier to better protection of abattoir workers against brucellosis is perceived inconvenience arising from use of gloves. Therefore, preventive and control measures against brucellosis must include education and use of PPE among abattoir workers.
