- Abstract
- Foodborne illnesses are a major global public health concern, causing significant morbidity and mortality. These illnesses are caused by the consumption of contaminated food. This study investigated the antimicrobial activity of Adansonia digitata leaves against foodborne bacteria Escherichia coli and Salmonella spp using disk diffusion assay. It was hypothesized that A. digitata leaves have antimicrobial effects against bacteria associated with foodborne illnesses. Methanol, ethyl acetate, and aqueous solvents were used for the extraction of extracts from A. digitata leaves. A. digitata leaves were collected from suitable trees in Mutoko. Methanolic A. digitata leaf extracts demonstrated a significant inhibitory effect of what value? against both Salmonella spp and E. coli while ethyl acetate and aqueous A. digitata leaf extracts did not show any significant antimicrobial effects. This finding suggests that methanolic A. digitata leaf extracts may be a potential source of antimicrobial compounds against foodborne pathogens. The lack of antimicrobial effects of ethyl acetate and aqueous A. digitata leaf extracts indicates that different solvents may be required to extract antimicrobial compounds from A. digitata leaves. Further research could explore the use of different solvents and extraction conditions to optimize the yield of antimicrobial compounds from A. digitata leaves. The potential use of A. digitata leaf extracts for food safety applications and disease control could be significant.
