To study the fungi contamination of shell peanuts harvested in 2012collected from 5regions in Linyi district, Shandong Provinces. MethodsUnshelled peanuts and soil samples collected at preharvest, harvest time, 1and 3months postharvest from different regions were inoculated onto PDA medium and the colony-forming unit of fungi were enumerated, classified and identified after incubation for 5days at (28±1) ℃. ResultsThe fungi contamination frequencies of the peanuts were approximately up to 100%. The species of fungi isolated from peanut kernels varied from region to region, and even different in the samples collected at different time from the same region. The contamination of peanut kernels by Aspergillus flavus was very low at the average percentage of 4.38%.ConclusionThe peanuts kernels collected from Linyi district of Shandong Province were severely contaminated by fungi but seldom by Aspergillus flavus. It was suggested that some important measures of mold prevention during storage should be taken.
