Mould contamination of milk products is a matter of significance in the field of food safety due to its related food spoilage

cheese types marketed in Zagazig city, Egypt. Roumy cheese had the highest total mould count followed by cheddar and
white cheese types. The prevalent mould genera were Aspergillus, Penicillium, Cladosporium and Alternaria. Further

Aspergilli. The public health importance of the prevalent mould genera was discussed
