Abstract
One hundred and fourty random samples of dried baby
foods with milk base representing seven brands (40 A and as locally-made. 40 C and D as imported and 60 E. F and G as infant’s milk powder) were collect from different shops or pharmacies in Assiut province. Every sample was examined microbiologically to evaluate its microbial quality as well as sanitary conditions. G samples, respectively. According to the standards recommended by ICMSF (1974) for aerobic plate count, all Egyptian baby food samples lie in the range of marginally acceptable quality. While 72.5 and 71.67 % of examined imported baby food and infant’s milk powder samples were of acceptable quality respectively. The enterococci count/g could be detected in 75, 65, 40, 60, 60, 45 and 50 % with mean values of 27.09xl03z 1.04xl02, 10.08xl02 Z 4.05xI02, 9.38xl02 Z 6.44xl02, 8.83xl0

C and E samples respectively, while such organisms failed detection in D, F and G samples.
Coliforms were isolated respectively from 100, 50, 5
and 5 % of examined samples of A, B, E and G. These organisms were identified as E. coli (25, 0, 0 and 5 %), Enterobacter
spp. (75, 40, 0 and 0 %) and klebsiella spp. (0, 10, 5 and o %) respectively.
Proteus spp., Providencia, Serratia spp. and Alkalescensdispar could be isolated at varying percentages from examined samples.
Clostridia were detected in 90, 70, 5, 10, 20, 20 and
15 % of examined sample. of A, B, C, D, E, F and G respeoti.e1y.Most of Egyptian itpes of baby foods contained relatively. A marked increase in total colony, B. cereus, coliform and enterococci counts was observed when the reconstituted baby food was stored for 15 hours at the ambient temperature.
Suggestive measures to improve the keeping quality and sanitary condition of the produced baby food are given.
