Background.  Scavengers, due to the nature of their work, are at risk of various occupational hazards while sorting for materials for recycling and sale. They are exposed to blood borne infections such as hepatitis B virus (HBV) infection from injuries from sharps and contact with discarded materials due to non-compliance with standard precautions.    Objective.  The present study assessed the prevalence of HBV and compliance with safety precautions among scavengers in Ilorin Metropolis, Kwara State, Nigeria.    Methods.  A cross-sectional study was conducted among 236 scavengers (comprised of scavengers dealing with biomedical wastes and those that were not) using structured questionnaires during the first stage of the study and a second testing stage. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software version 20.0 for descriptive and inferential statistics at a 5% level of significance.    Results.  The prevalence of HBV infection among the scavengers was found to be 17.4%, indicating that scavengers are at high risk of HBV infection. There was a significant difference in the prevalence of HBV among scavengers that handled biomedical wastes and those that did not. The majority of the scavengers (74.2%) did not have knowledge of or use standard precautions such as personal protective equipment (PPE). The level of injuries was considerably high and the treatment of injuries among scavengers illustrated their lack of awareness of the hazards involved in their occupations, as the majority of respondents (51.3%) engaged in self-treatment of occupational injuries.    Conclusions.  The probable pathway for virus transmission was waste handling, especially biomedical waste, which is mostly handled with bare hands without standard safety precautions. Vaccination against HBV, proper personal hygiene practices, regular training in occupational safety, monitoring by regulatory agencies and inclusion of scavengers in a mandatory health insurance scheme are recommended to control the risk of HBV infection among scavengers.    Informed Consent.   Obtained    Ethical Approval:  This study was approved by the Kwara State Ministry of Health Ethical Review Committee. Permission was also granted by the scrap dealers association through the Kwara State Environmental Protection Agency that oversees issues relating to the environment and public health in the state.
