The purpose of this study was to determine the impact of occupational health hazards and safety practises on abattoir workers in Owerri Metropolis, Imo State, Nigeria. For the study, three objectives and three questions were developed. This study used a descriptive survey design. The population of the study consisted of 232 abattoir workers recruited from the three major abattoirs in Owerri Metropolis, Imo State. The study's sample included all two hundred and thirty-two (232) abattoir workers from the three major abattoirs in Owerri Metropolis. At the 0.05 level of significance, inferential statistics of Chi square (x2) were used to analyse the data collected for hypotheses, while the objectives were presented in frequency and percentages. According to the findings, the major occupational health hazards include knife cuts, blood/waste splashes, noise, bone piercing, and chemical spill, burns, and irritation. Adopted safety practises include the use of an apron, gloves, boots, and pre- and post-mortem inspection. Based on the findings, it was recommended that the government, through the ministry of health and labour, develop or create survey instruments and conduct surveys on a regular basis to monitor the prevalence of occupational health diseases and the upkeep of safety practises in abattoirs.
