title: Occurrence of moulds from bee pollen in Central Italy--A preliminary study.
abstract: The present study aimed to preliminary evaluate the occurrence of fungi in 40 specimens of trapped pollen collected from April-September 2015 in 40 apiaries from Tuscany (Central Italy). Cultural and microscopical examinations allowed the recognition of Cladosporium sp., Alternaria sp., Humicola sp. Mucoraceae and Acremonium sp. Penicillium brevicompactum, Penicillium chrysogenum, Aspergillus flavus , Aspergillus nidulans, Aspergillus niger and Aspergillus terreus were also identified. Yeasts and Fusarium spp. were not isolated. All pollen specimens were positive for at least one fungal isolate. Total CFU per gram ranged from 4-568. Aspergillus and Penicillium were obtained from 8 (20%) and from 22 (55%) pollen samples, respectively, associated in 4 cases (10%). The recovery of storage fungi such as Aspergillus and Penicillium in trapped pollen presents a potential risk for human health and attention should be paid to all stages of the post-harvest process.
