Abstract
A total of 30 moin-moin samples wore collected from three
food sales outlets namely, hawkers, cafeteria and restaurant
were analysed for total aerobic plate count, staphylococcus
aureus and B a c i 11us cereus. Moin-moin samples obtained from
the restuarant showed slightly lower values for total aerobic
plate count (1.3 x 10 - 1.6 x 106 ) as compared to counts
obtained from cafetaria and hawkers (2.7 x 104 - 2.6 x 106
and 4.6 x 104 - 3.2 x 106 ) respectively. Staphylococcus aureas
count from moin-moin samples obtained from hawkers varied
between 1.2 x 103 - 2.0 x 105 while that of cafetaria and
restaurant showed count varying between ( 1 .3 x 103 - 1.0 xlO5
and 2.2 x 103 - 1.1 x 105 ). Baci1lus cereus count from
moin-moin samples obtained from hawkers varied between
(1.0 x 103 - 1.3 x 104 ) and that of cafeteria and restaurant
varied between (1.0 x 1022- 2.1 x 104 and 1.0 x 103 - 1.0 xlO4
respectively. The enterotoxin producing ability of the 13
randomly selected isolates of s. aureus using cellophane over
agar method. Seven (53%) of the isolated produced enterotoxin
A while none produced enteroxin C and D. Fifteen isolates
Bacillus cereus were tested.for toxin production using rabbit
ileal loop test. Ten 66% of the strain wore mild enterotoxin
producers and 5 (33%) were moderate enterptoxin producer.
Fifteen other 'moin-moin samples's observed for shelf
stability showed that moin-moin could remain wholesome for
18hrs, 30hrs, and 42hrs at a storage temperature of 25oc ,
(ambient temperature) 30Oc and 20Oc.
