Abstract

Vegetable can serve as a source of food and it can be contaminated by microorganisms and parasite which can serve as a source of diseases. Laboratory investigations were carried out on four different vegetable samples: Cochorus olitorius (Ewedu), Celosia argentea (Shoko), Daucus carota (Carrot), Brassica olerecea (Cabbage), purchased from retailers in Owena-Ijesa, Nigeria. Standard Microbiological and parasitological analysis were carried out. Staphylococcus sp., Bacillus sp., Proteus sp., Enterobacter sp., Salmonella sp., Enterococcus sp., Vibrio sp., Paenibacillus sp., Pseudomonas sp., Escherichia sp., Brevibacillus sp. and seven fungi Saccharomyces sp., Penicillium sp, Aspergillus niger, Rhizopus stolonifer, Trichoderma harizianum, Mucor sp. and Fusarium sp. were isolated and identified from the vegetables. The highest total bacterial count was 8.0 × 104 and lowest fungal count was 1× 103 in cabbage. E. coli had the highest occurrence of 18.18% and was found on all marketed vegetable samples used in this study while P. aeroginosa, B. subtilis and B. brevis had the least occurrence of 3.03%. Saccharomyces sp, Penicillium sp, and Aspergillus niger had the highest occurrence of 20% while Rhizopus stolonifer, Trichoderma harizianum, Mucor sp. and Fusarium sp. had the least occurrence of 10%. This study showed the presence of organisms of health significance on retail vegetables, reduction of risk of human illness can be achieved through controlling points of potential contamination from handling, transportation, processing of raw vegetables and strict government laws banning the use of untreated fertilizer on farm produce.
