Abstract
This study was done to assess the microbial and parasitic infestation of fresh fruits and vegetables in two major markets in Lokoja metropolis. A total of 24 fruits and vegetables were purchased from the 2 markets, they were washed, and were examined for microbial and parasitic organisms. The total bacterial, coliform and fungal counts on the samples from Ganaja market ranged from 0.6 – 5.9 x 104 cfu/g, 0.0 - 3.1 x 104cfu/g, 0.0 – 3.2 x 104cfu/g respectively while for Adankolo Market it ranged from 0.2 – 4.0 x 104cfu/g, 0.0 – 1.3 x 104cfu/g, 0.0 – 3.9 x 104cfu/g respectively. Predominant bacteria isolated include: Klebsiella sp., Pseudomonas sp., Salmonella sp., Shigella dysenteriae , Staphylococcus aureus, Escherichia coli, Serratia sp., Proteus sp. and Enterobacter sp. The parasitic eggs observed include: Capillaria hepatica, Fasciola sp., Hymenolepsis nana, Dermatobia hominis, Spongyloides sp., Taenia sp., Trichuris vulpis, Ascaris lumbricoides, Paragonimus westermani, Schistosoma haematobium, Spongyloides stercoralis, Dipylidium caninum, while the parasitic larvae include Zygnema sp., Trichuris sp., Hook worm, Tape worm and Dipylidium sp., Telfairia occidentalis, Vernonia amygdalina, Hydrophylum triangulare, Cucumis sativus and Corchorus olitorie showed high level of infestations both bacteriologically and parasititologically with Ganaja market having the highest level compared to Adankolo Market. Findings indicates that fruits and vegetables can be potential source of microbial and parasitic infestation, there is a need for consumers to know the risk of consuming infested fruits and vegetables sold in the markets.
