Pathogenic Bacterial Species in Locally Prepared Fresh Fruit Juices Sold in Juice Houses of Eastern Ethiopia

Fruit juices are important components of a healthy diet and a dietary source of nutrients, vitamins, and fiber and vital for human health. However, unless it is handled with safety and hygienic conditions, food can be a vehicle for the transmission of various agents of diseases resulting in food borne outbreaks. Thus, this study aimed to determine common pathogenic bacterial species in locally prepared fresh fruit juices sold in juice houses of Eastern Ethiopia. A cross-sectional study design was conducted from 1 January to 27 March 2020, in eastern Ethiopia. Seventy-eight juice samples were collected aseptically using a sterilized collecting jar from each juice house. Pour plate count method was used to determine Staphylococcus, Salmonella, and Shigella species. Finally, the data were analyzed using descriptive statistical tests such as Chi-square and Fisher’s exact tests. P-value of .05 was considered as a cut point for statistical significance. The study found Staphylococcus count ranged from 1.68 log CFU/mL with the mean value of 4.204 log CFU/mL. Overall, 58 (74.4%) of the fruit juice samples had Staphylococcus count, 19 (24.4%) had Salmonella and 12 (15.4%) had Shigella higher than the maximum permitted limit of Gulf standard, 2000 set for any type of fruit juice. In general, the study found more than two-thirds of fruit juice samples had at least 1 pathogenic bacteria species higher than the maximum permitted limit and potentially hazardous to consumer health. Thus, regular supervision and application of food hygiene and safety are essential to improve the quality of fruit juice and to prevent the consumption of contaminated fruit juices, which leads to food borne illness.
