ABSTRACT
This study determined
the microorganisms associated with spoilt Avocado pear. Ten (10) samples each
where purchased at
different markets in Umuahia Metropolis Ndoro and Ahiake Markets). The Avocado
pear samples collected
were fresh, undamaged, firm, healthy and ripe. The samples were dispensed into
clean bags and then
brought to the laboratory. The samples were left free of dust, insect and were
under
room temperature for 6
days to undergo natural process of spoilage before being used in the study.
Bacteria
such as Bacillus
subtilis, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae,
Serratia
marcescens and
Staphylococcus aureus were isolated while fungi such as Aspergillus niger,
Aspergillus
flavus, Rhizopus
Stolonizer, Rhodotorula spp were equally isolated. Mean average bacteria load
ranged
from 20.5 x 106to 71.55
x 106.The mean average bacteria load ranged from 1.55 x 108 to 21.3 x 106.The
mean average bacteria
load ranging from to 29.3 x 106 to 5.6 x 106 The mean average bacteria load
ranged
from 33.6 x 106 to 5.9
x 106. Escherichia coli had the highest frequency occurrence of 10(23.2%),
followed
by Klebsiella pneumonia
and Staphylococcus aureus with frequency of 6(13.9%), while Serratia
marcescens and
Rhodotorula spp had the leasti 3(4.7%). These microorganisms are responsible
for
spoilage of Avocado
pear.
