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.
