Bacteriological Evaluation Of Pre-Cut Fruits Sold In Kano Metropolis, Kano State, Nigeria
Abstract
One hundred and fifty (150) pre-cut fruit samples comprising of Pineapples (50), Paw-paw (50) and Watermelon (50) at the point of stand
retail outlets were tested by standard bacteriological methods to determine bacterial contamination of the fruits. Out of these 150 examined
136 (90.67%) were contaminated with bacteria. The bacterial distribution were; Escherichia coli 69 (46.00%), Staphylococcus aureus 29
(19.33%), Salmonella species 13 (8.67%), Proteus species18 (12.00%), Enterobacter aerogenes 3 (2.00%), Klebsiella pneumoniae 2 (1.33%)
and Pseudomonas aeruginosa 2 (1.33%). Among the 50 Pineapple pre-cuts, Escherichia coli 26 (17.33%), Staphylococcus aureus 6 (4.00%),
Salmonella species 7 (4.67%), Proteus species 9 (6.00%), Pseudomonas aeruginosa 2 (1.33%); the 50 Watermelon had Escherchia coli 22
(14.67%), Staphylococcus aureus 13 (8.67%), Salmonella species 3 (2.00%), Proteus species 5 (3.33%), Enterobacter aerogenes 2 (1.33%),
Klebsiella species 2 (1.33%). Of the 50 Paw-paw pre-cuts were; Escherichia coli 21 (14.00%), Staphylococcus aureus 10 (6.67%), Salmonella
species 3 (2.00%), Proteus species 4 (2.67%), Enterobacter aerogenes 1 (0.67%) were isolated. The findings in this study have shown that
the food vendors failed to adopt adequate hygiene for food handling and thus, suggest that the quality of all the pre-cut fruits sold at the
retail outlets were not bacteriologically satisfactory. The public health risks associated with these pre-cut fruits may suggest that these fruits
could serve as the vehicles for foodborne illnesses. This study has shown the need to educate the vendors on how to protect utensils and
fruits to avoid contamination and spoilage
