according to Barnett’s and physiologically by API technique to identify the
species of Yeasts, whe
re had found 10 classified yeasts as follows:
Candida krusei is the most of yeasts which founded in whey with 21.66 %,
and in the Second rank is Candida lusitaniae with 16.66 %. the third rank came

the lowest concentration (5.72 μg/kg diet) in canned fruits and in the highest
concentration (121.35 μg/kg) in cereal samples ranged. Other interface levels of
leads were found in the other baby food and reached 20.41μg/L in human milk,
