Background. Healthcare workers are at high risk of occupational exposure to needle stick injury worldwide. Occupational exposure to needle stick injury represents the most common sources of infection such as hepatitis B virus, hepatitis C virus, and human immunodeficiency virus. Thus, this review aimed to determine the career time and previous one-year global pooled prevalence of occupational exposure to needle stick injury among healthcare workers. Methods. The review considered articles written in English language and published from 2012 to 2020. The articles were searched using nine electronic databases (PubMed, Google Scholar, CINAHL, MEDLINE, Cochrane library, Web of Science, SCOPUS, MedNar, and ScienceDirect) using a combination of Boolean logic operators (AND, OR, and NOT), Medical Subject Headings, and keywords. Quality assessment was performed to determine the relevance of the articles using Joanna Briggs Institute critical appraisal tools. Several steps of assessment and evaluation were taken to select and analyze the relevant articles. Results. The worldwide pooled prevalence of needle stick injuries among healthcare workers during career time and previous one year was 56.2% (95% CI: 47.1, 64.9) and 32.4% (95% CI: 22.0, 44.8), respectively. The career time pooled prevalence of needle stick injuries based on the socioeconomic development and study area was 54.8% and 55.1%, respectively, and one-year pooled prevalence of needle stick injury was 26.0% and 20.9%. Conclusion. The review found a high prevalence of occupational exposure to needle stick injury among healthcare workers and suggests the need to improve occupational health and safety services in the healthcare systems.

Background Healthcare workers are at high risk of infection from blood‐borne pathogens, such as Hepatitis B and C Virus, and Human Immunodeficiency. Occupational exposure to needle‐stick injuries (NSIs) continue to have a major health problem in the healthcare systems of developing countries. Thus, this review article aimed to provide the evidence on the prevalence of NSI and associated factors among healthcare workers of developing countries. Methods The studies published from 2012 to 2019 were identified through systematic searches of electronic databases such as PubMed, Google Scholar, CINAHL, MEDLINE, Scopus, Med Nar, and Science Direct. The MeSH terms and/or keywords was used in conjunction with “AND” or “OR” (Boolean logic operators). All identified keywords and an index terms were checked across the included databases. Assessment and evaluation were taken to confirm the quality and relevance of the included articles, followed by extraction and analysis of data. Result Overall, 2021 articles were identified using specified search terms from the initial searches of the literature (2012‐2019). A total of 13 articles met eligibility criteria were included in the review. Among 6513 participants, 1009 and 2201 participants involved to determine 1‐year and throughout career prevalence, respectively. The prevalence of NSI ranged from 19.9% to 54.0% with an overall prevalence of 35.7% and 38.5 to 100% with an overall prevalence of 64.1% in the previous 1 year and throughout career, respectively. Sex, workload, needle recapping, overuse of injection, and practice of universal precautions, training, occupation, working experience, and personal protective equipment were among the factors associated with the prevalence of NSIs in developing countries. Conclusion The review indicated that NSIs have been identified as one of the most serious issues that affect the health and well‐being of healthcare workers in the majority of healthcare systems of developing countries. There is a need to apply safety practices or other measures to reduce the risk of NSIs.

Background. The issue of microbial quality and safety of ready-to-eat foods has become a public health concern that needs to be addressed to protect the consumer’s health. Contamination of ready-to-eat foods by enteric pathogens such as Escherichia coli, Salmonella, and Staphylococcus aureus bacteria is associated with potential health risks and can cause foodborne outbreaks. Thus, the systematic review and meta-analysis aimed at determining the overall evidence on the prevalence of microorganisms of public health significance in ready-to-eat foods based on previous studies. Methods. The articles published from 2015 to 2020 were searched from multiple electronic databases such as PubMed, Google Scholar, MEDLINE, CINAHL, Science Direct, Web of Science, and the Directory of Open Access Journals. The JBI critical appraisal tool was applied to the included articles. To determine the heterogeneity among the included articles, I 2 statistics were used while publication bias was evaluated using the visual funnel plot. A Forest plot using the random effect model for meta-analysis was used to estimate the pooled prevalence of E. coli, Salmonella, and S. aureus in ready to eat foods. Results. The pooled prevalence of E. coli, Salmonella, and S. aureus in ready to eat foods was 33.8% (95% CI: 19.9, 51.2; Q   value = 67.080 , I 2 = 89.56 % ), 26.0% (95% CI: 13.8, 43.6%; Q   value = 83.67 , I 2 = 91.63 % ), and 46.3% (95% CI: 24.8, 69.4%, I 2 = 94.9 % ), respectively. Conclusion. The findings show that contamination of ready-to-eat foods with pathogenic microorganisms continues to be a public health risk. Thus, effective food hygiene and safety systems are necessary to protect the health of the consumers and the public as a whole.

Background: Municipal solid waste collection is one of the most dangerous jobs in the world since it exposes the workers involved to occupational hazards and predisposes them to certain occupation-related morbidities. Occupational injuries among municipal solid waste collectors have not been adequately addressed or reported in developing countries, including Ethiopia. Therefore, this study aimed to determine the prevalence of occupational injuries and associated factors among municipal solid waste collectors in Harar Town, Ethiopia. Methods: A cross-sectional study was conducted in Harar town, Eastern Ethiopia from May 25, 2021 to June 25, 2021. Three hundred eighty-nine (389) municipal solid waste collectors were selected using a simple random sampling method. A self-administered structured questionnaire and an observational checklist were used to collect the data. The collected data was analyzed using SPSS version 20. Bivariate and multivariable logistic regression were used to determine the association between independent variables and the outcome variable. A P-value of <.05 was considered as a cut-off point for statistical significance. Results: The current study found that about 60.4% of municipal solid waste collectors were exposed to occupational injuries. Furthermore, the study found a statistically significant association between the prevalence of occupational injuries and having a primary education [AOR = 0.10, 95% CI (0.03-0.38)], a secondary education [AOR = 0.04, 95% CI (0.03-0.45)], work experience [AOR = 5.975, (95% CI (2.01-17.75)], the use of personal protective equipment [AOR = 0.09, (95% CI: 0.02-0.46)], and training [AOR = 0.10, 95% CI (0.03-0.30)]. Conclusions: The current study found that more than three-fifth of municipal solid waste collectors were exposed to occupational injury. Furthermore, the current study found that there was an statistical relationship between the prevalence of occupational injuries and having a primary education, a secondary education, work experience, the use of personal protective equipment, and training. Before and after hiring solid waste collectors, employers should provide personal protective equipment and tailored training on safety measures.

As agricultural production in African countries intensifies; pesticide utilization becomes more widespread and the users are extremely exposed to these pesticides due to lack of pesticide registration scheme; importing highly toxic pesticides; no national plan for pesticide residue; involvement of children and women. The purpose of this systematic review was to review adverse effect of pesticide among top ten imported African countries. In  this review, top ten importers African countries were selected based of imported amount for ten years were considered from imported period of 2002 to 2017. The articles were searched from PUBMED, GOOGLE SCHOLAR, and MEDLINE and EMBASE engines. The first leading three continents for pesticides exported were European (48.2%), Asian (33.7%) and North America (12.7%), while the countries were China (14.3%), Germany (11.8%) and United States (11.5%) at the end of 2017. The first three leading importer of African countries were South Africa shared (25.7%), Nigeria (15.8%) and Ghana (14.5%). The three major imported pesticides were Fungicides, herbicides and insecticides. In this review, Ethiopia (827), Kenya (801), and Morocco (542) are the main importers of pesticides until end of 2017. The review also found that farmers were faced with endocrine disruption, carcinogenicity, mutagenicity, teratogenicity, cardiovascular, dermatitis and birth defects. The main associated factor for these problems were low awareness, improper handling of pesticide, and lack of training, and careless disposal of empty pesticides containers. The study concluded that more than one billion US$ of pesticides sales was carried out into ten African countries. The farmers within these country were faced different  health problems due to different determinant factors. Proper training and education should be advised for farmers  Keywords: Adverse effect, African countries, Import, Pesticide
