The lack of hygiene in public markets in rural areas is often linked to poor management of the waste produced there. This waste makes the environment unhealthy and pollutes the various consumer products sold, hence the source of illnesses. This study is carried out in the city of Kabinda province of Lomami in the Democratic Republic of Congo (DRC). The Yakasongo market west of Kabinda was the center of investigation. Eighty-four (84) vendors were questioned. Data analysis was done using SPSS 22 software. The Chi-square test was used to verify the relationship between vendor perceptions of hygiene and the occurrence of diseases. The epidemiological odds ratio index to determine the degree of exposure to diseases. The results show that there is a statistically significant relationship between the perception of market hygiene and exposure to diseases.
