“…Physical damage during harvest can lead to the spread of soil-borne pathogens, such as Erwinia carotovora, Botrytis cinerea, Fusarium solani and Rhizoctonia solani.

Improper distribution and storage management can also reduce the pharmacological and commodity value of ginseng.…”

BACKGROUNDFresh ginseng is typically accompanied by soil after harvest, leading to contamination with harmful fungi during storage and distribution. In this study, we investigated the incidence of fungal contamination in fresh ginseng (5–6 years old) purchased from 22 different stores in Geumsan, Korea.RESULTSThe incidence of fungal contamination in the samples was 67.4–111.5%. Fusarium solani was the most abundant species in the head (38.5%) and fine root (19.3%) parts of the ginseng samples, whereas F. oxysporum was the most abundant in the main root (22.0%) part. We isolated Aspergillus, Fusarium and Penicillium spp. (total number of isolates: 395) from the ginseng samples, and 138 isolates were identified using phylogenetic analysis. Polymerase chain reaction‐based screening of 65 mycotoxin‐producing species revealed that two P. expansum isolates were positive for citrinin and/or patulin, and five F. oxysporum isolates were positive for fumonisin biosynthesis gene. One P. expansum isolate produced 738.0 mg kg−1 patulin, and the other produced 10.4 mg kg−1 citrinin and 12.0 mg kg−1 patulin on potato dextrose agar (PDA) medium. Among the 47 representative F. oxysporum isolates, 43 (91.5%) produced beauvericin (0.1–15.4 mg kg−1) and four of them (8.5%) produced enniatin B and enniatin B1 (0.1–1.8 mg kg−1) as well. However, none of these toxins was detected in fresh ginseng samples.CONCLUSIONFusarium solani and F. oxysporum were the most abundant species in fresh ginseng samples. Most F. oxysporum (43) and P. expansum (2) strains isolated from fresh ginseng produced beauvericin and enniatins (B and B1), and patulin or citrinin, respectively, on PDA medium. This is the first report of the mycotoxigenic potential of P. expansum and F. oxysporum strains isolated from fresh ginseng. © 2024 Society of Chemical Industry.
