Evaluation of Hygienic Practices and Microbiological Quality of Street Vended Fruit Salads in Morogoro, Tanzania

Abstract

Street vended foods have gained popularity due to economic benefits. However, they have been recognized as a potential hazard to public health as a result of poor hygienic practices. The study was conducted to assess the hygienic practices and microbiological quality of street vended fruit salads vended in Morogoro Municipal, Tanzania. A total of 30 respondents were involved in the study to assess of quality of fruit salad vended by town street vendors (TSV), University cafeterias (UCV), and town restaurants vendors (TRV). The findings revealed that most vendors (86.3%) were unaware of food safety, 73.3% were unaware of food safety standards and laws, and every seller evaluated was unaware of food safety initiatives such as Good Manufacturing Practices (GMP) and Good Hygienic Practices (GHP) and had never implemented any of them. All vendors saw the doctor only when they were ill. Nevertheless, none of vendor had a quality registration certificate or had undergone training in food safety and hygiene. Most of the salad preparation settings (46.7%) did not adhere to the fundamental requirements of a food preparation facility, and the vending facilities were in disrepair. Piles of dirty were observed in the food salad preparation and vending premises and 80% of the vendors used uncovered waste bins that were observed to encourage pests such as flies and cockroaches in the premises. The total aerobic count (TAC) ranged from 3.92±0.31 to 4.29±0.21 log CFU/g. All fruit salad samples were contaminated with coliforms and the level of coliform count exceeded 1.4×104 MPN/g in fruit salad samples indicating poor hygiene and fecal contamination. Possible sources of contamination were found to be water quality, cross-contamination, food handling and preparation equipment, and environmental factors such as dust, pests, and air quality. According to the study's findings, the majority of fruit salad sellers in the study area did not adhere to hygienic practices, and the made fruit salads were of poor microbiological quality, putting consumers at risk for food safety.
