Occurrence of mycobiota and aflatoxin m1 in some dried dairy products

Abstract EN

A toial of 110 samples of dried diary products implemented as full crenm mi!k powder (50 sachets) were randomly collected from groceries & supermarkets and dried casein (30) and dried whey (30) in sterile polyethylene bugs from large factories in Alexandria Governorate.

All samples were stiH valid for consumption as shelf -life is at least to be one year Iroro production time.

The coilccted samples were Transmiued to the laboratory for preparation.

The samples wore examined t<> determine the levels of fungal contamination and the possible presence of anatoxin M;.

J"hc obtained data pointed out that 40, 36 67 and 43.33% of the examined samples of milk powder, dried casein-and dried whey were contaminated wiih molds with average counts of 2.2 X10" 4.2 X 103, and 2.1 X 102 /g, respectively.

Aspergillus was the prevalent genus encountered in the examined samples followed by genus Penicillium.

5 out of 14 isolated strains olA flaws (35.71%) proved to be aflutoxin )ii (AFliO producers with diQcren! concentrations.

Aftatoxins M; could be delected in the examined milk powder, dried casein and dried whey samples, using RL1SA, with concentration levels of 0.07-0.6, 0.02-0.06 and 0.03-0,08 ug|kg, respectively.

All positive samples were not complied with F.gypiian Standards (1990; which stated dial milk and milk products should be free from any anatoxins.

So, efforts have to be made to prevent mold growth and anatoxins production along the entire food chain specially food related lo children.
