Abstract
Five samples of egusi (melon seed) soup collected from different
food vendors in (Campus 3) of the Institute of Management and
Technology, Enugu were studied for bacteria spoilage. Different media
were prepared and they include: MacConkey agar medium, nutrient
agar medium, and blood agar medium. After 24 hours of culturing on
the media, observation of the plates incubated aerobically show heavy
and profused growth of Bacillus cerus, moderate growth of
Escherichia coli and Klebsiella aerogenes as well as scanty growth of
Streptococcus feacalis and Staphylococcus aureus. The presence of E.
Coli and Streptococcus feacalis indicated faecal contamination of the
soup as these two organisms are known to be indicator organisms.
They are usually associated with poor hygienic handling of foods,
water, utensils and vegetables. Having known the spoilage organisms, the shelf life of egusi
(melon seed) soup could be extended and improved by subjecting the soup to a more
advanced preservation methods such as canning and drying.
