- The study examined Ziziphi Spinosae Semen, a Chinese herbal medicine, for aflatoxin contamination and identified fungi responsible for it by analyzing 32 samples from different processing stages using specialized methods.
- Aflatoxins were found in 28 samples, with the highest contamination from washing, exceeding safety limits set by the Chinese Pharmacopoeia; specifically, aflatoxin B1 was present in three samples.
- Fungal contamination increased through processing, particularly due to composting and washing, with Aspergillus flavus identified as the main source of aflatoxins, emphasizing the need for monitoring during production.
