Currently, the sale and consumption of hot beverages are increasing in Côte d'Ivoire streets, and the health risk assessment is still not well documented. It was then important to assess the health risks associated with potentially pathogenic microorganisms in these beverages, as well as their antibioresistance in the context of food safety. For this purpose, a survey including 500 hot beverage consumers was carried out in Abidjan streets. A total of 600 samples, including coffee (150), tea (150), milk (150), and cocoa (150), were aseptically collected from five locations in Abidjan city to determine their microbiological quality. The microorganisms isolated from beverages were identified using MALDI-TOF MS. A low prevalence of S. aureus (3.0%), E. coli (2.3%), K. pneumoniae (1.5%), B. cereus (1.3%), C. tropicalis (1.5%), and C. parapsilosis (1.0%) was detected in ready-to-drink beverage samples. Moreover, some microbial isolates were variously resistant to the antibiotic used in this study. Indeed, S. aureus was resistant to erythromycin, K. pneumoniae to piperacillin, B. cereus to penicillin, ampicillin and C. tropicalis to fluconazole. The presence of such antibiotic resistant strains constitutes a real risk health factor. Moreover, the survey on hot beverage street sellers and consumers showed that the conditions of hot beverages processing as well as materials handling, and seller’s hygiene can be sources of contamination of pathogenic microorganisms. Street hot beverage consumers and sellers must improve hygienic conditions to prevent cross-contamination from human handling during food processing.
