Post-fermented tea (PFT), a commonly consumed beverage worldwide, is characterized by the rapid growth of its microbial groups and the substantial changes they undergo. Consequently, PFT may contain mycotoxins such as B-type fumonisins (FBs). This study aimed to assess the intake of FBs through the consumption of PFT among consumers in Guangxi, China. A novel quantitative method using high-performance liquid chromatography-mass spectrometry was used to determine the FB concentration in PFT products. Additionally, a PFT consumption survey was conducted using a face-to-face questionnaire, recording their body weight and PFT consumption patterns based on a three-day dietary recall method. Finally, hazard index was calculated to estimate the health risk of FBs from the consumption of PFT products in Guangxi. The results revealed that the occurrence of FBs in PFT was 20% (24/120), with a concentration ranging from 2.14 to 18.28 μg/kg. The results of the survey showed that the average daily consumption of PFT by consumers was 9.19 ± 11.14 g. The deterministic risk assessment revealed that only 0.026% of the provisional maximum tolerable daily intake of FBs was consumed through PFT, indicating that FB contamination in PFT is not a public health risk.
后发酵茶（PFT）是一种在全球广泛消费的饮品，其特点是微生物菌群快速生长且经历显著变化。因此，PFT可能含有诸如B型伏马毒素（FBs）等霉菌毒素。本研究旨在评估中国广西消费者通过饮用PFT摄入FBs的情况。采用一种新型的高效液相色谱 - 质谱定量方法来测定PFT产品中的FB浓度。此外，通过面对面问卷调查进行了PFT消费调查，基于三日饮食回顾法记录他们的体重和PFT消费模式。最后，计算危害指数以评估广西饮用PFT产品摄入FBs的健康风险。结果显示，PFT中FBs的检出率为20%（24/120），浓度范围为2.14至18.28μg/kg。调查结果表明，消费者每日PFT的平均消费量为9.19±11.14g。确定性风险评估显示，通过PFT摄入的FBs仅占暂定每日最大耐受摄入量的0.026%，这表明PFT中的FB污染并非公共卫生风险。
