Description The aim of this study was to investigate the fungal community associated with fruits and vegetables transported into the Antarctic region and observe qualitative changes of their surface mycobiota after UV-C treatment. This measure is used to prevent the post-harvest diseases of stored fruits and vegetables and reduce the risk of introducing non-native species to the Antarctic environment. In total, 82 strains of filamentous fungi were isolated from the surfaces of 64 pieces of fresh fruits and vegetables before and after their UV-C treatment. They were assigned to the genera Penicillium, Fusarium, Mucor, Cladosporium, and Acremonium. After the UV-C treatment of the examined fruits and vegetables, spores of the genera Fusarium, Cladosporium and Acremoniumwere not detected, while spores of the genera Penicillium and Mucor were more resistant and stayed viable after the treatment. Penicillium strains prevailed in the examined samples. Their introduction to the Antarctic environment could represent a potential risk for endemic autochthonous organisms.
