Occurrence and Diversity of Mold Species in Raw Milk and Dairy Products

Article excerpt

Background: This study aimed to investigate the occurrence and diversity of mold species in bulk-raw milks and different dairy products in East-Azerbaijan province.

Methods: A total sample of 105 milk and dairy products were analyzed using conventional culture methods. After preparation of sample suspensions/emulsions, they were cultured on Saboraud Dextrose agar and incubated at ~25°C for 1-2 weeks. In order to identify the mold species, the iso- lates were examined using slide-culture method followed by microscopic observation.

Results: According to the results, mold contamination was determined in 92% (46/50) of bulk-raw milks. Mold species were identified as Aspergillus spp., Penicillium, Geotrichum, Alter- naria and Fusarium. In the case of dairy products, the contam- ination was found in 24% (12/55) of the samples. The most isolated species were Aspergillus, Penicillium, Mucor and Scopular- iopsis.

Conclusion: Results suggested that milk production and collection in this area was performed in non-hygienic condi- tions since almost all of the bulk-milk samples were contami- nated with various mold species. …
