“…Staple dietary foods such as maize, groundnuts, rice and milk are highly susceptible to aflatoxin contamination, making them a real threat to food security, safety and population health 5 , 6 . As a result, exposure to aflatoxins via the diet is associated with various health consequences 7 , 8 .…”

Aflatoxins are mycotoxins that contaminate staple foods globally and pose a significant health risk. To the best of our knowledge, information on the occurrence of aflatoxins in Bhutanese diets is scarce. This study aimed to estimate the aflatoxin levels in selected foodstuffs in Bhutan and determine the health risk associated with aflatoxin exposure. Ten different types of food commodities were randomly collected from farmers’ markets, shelves of supermarkets, and wholesale and retail shops from 20 districts of the country. The samples were subjected to analysis by an enzyme-linked immunosorbent assay for both total aflatoxins (B1, B2, G1 and G2) and aflatoxin B1. Among the 315 samples included, 48.81% and 79.35% were positive for total aflatoxins and aflatoxin B1, respectively. The overall mean total aflatoxin concentration was 11.49 ± 12.83 µg/kg, and that for B1 was 17.62 ± 23.99 µg/kg. The most prevalent food commodity with the highest aflatoxin contamination was chili products. In addition, the estimated daily intake and margin of exposure to aflatoxin B1 via the consumption of chili products ranged from 0.98 to 5.34 ng kg−1 bw day−1 and from 74.90 to 408.10, indicating a risk for public health. The liver cancer risk was estimated to be 0.01 and 0.007 cancers per year per 100,000 population resulting from the consumption of chili products. The present findings revealed the presence of total aflatoxins and aflatoxin B1 in the selected samples. The margin of exposure values was exorbitant, demanding a stringent public health measure. Notably, these results suggest the need for routine monitoring of aflatoxin contamination in the region and stress rigorous safety management strategies to reduce exposure.

In the present study, the efficacy of low-cost biosorbent obtained from walnut shells for the removal of AFB1 was examined. The characterization of the biosorbent was investigated using SEM, EDS, FTIR, XRD, and pHpzc. Maximum removal (90.5 %) was achieved using 100 mg/mL of biosorbent, pH 7.0 at 45 °C for 45 min with 100 ng/mL of AFB1. The biosorbent’s adsorption capacity was found to be 178.9 mg/g as calculated using the Langmuir isotherm and assumption of monolayer AFB1 adsorption with homogenously dispersed adsorption positions on the biosorbent exterior. The kinetic data indicated the fast AFB1 uptake on biosorbent and followed the pseudo-second-order model. The thermodynamic factors revealed that the adsorption process is viable, spontaneous and endothermic. Furthermore, slight decrease in AFB1 adsorption was observed after repeating the adsorption–desorption process for 5 times. In conclusion, the obtained biosorbent is an economically, eco-friendly and promising material for the removal of AFB1.
