What does this research mean for the field?

Over half of dried fruits and nuts sold in Dhaka, Bangladesh, are contaminated with aflatoxins, with more than a third exceeding European Commission safety thresholds and posing a significant liver cancer risk, particularly to HBsAg-positive individuals. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To quantify toxigenic fungal contamination, measure aflatoxin concentrations, and assess dietary exposure and liver cancer risk from dried fruits and nuts sold in Dhaka, Bangladesh.

Implication

Surveillance study finds widespread aflatoxin contamination across market dried fruits and nuts, highlighting elevated liver cancer risk particularly in hepatitis B carriers.

Key Points

To quantify toxigenic fungal contamination, measure aflatoxin concentrations, and assess dietary exposure and liver cancer risk from dried fruits and nuts sold in Dhaka, Bangladesh.
Collected dried fruit (raisins, dates) and nut samples from markets in Dhaka city, Bangladesh.
Cultured and enumerated fungal isolates (CFU/g) and quantified aflatoxins B1, B2, G1, and G2.
Calculated human dietary exposure levels (ng/kg-bw/day) and modeled liver cancer risks according to Hepatitis B surface antigen (HBsAg) status.
Aflatoxins occurred in 57.14% of samples (ranging from 1.22 to 81.97 μg/kg), with more than one-third surpassing the European Commission regulatory limit of 4 μg/kg.
Mean aflatoxin concentrations were 44.38 ± 34.19 μg/kg in raisins, 4.15 ± 0.32 μg/kg in dates, and 3.27 ± 1.79 μg/kg in nuts, with Aspergillus species (95.23%) and aflatoxin B1 predominating.
Estimated dietary exposure ranged between 1.50 and 27.31 ng/kg-bw/day, imparting the greatest risk of liver cancer to individuals with positive HBsAg status.
