1 Sera from 28 Nepalis, both patients and workers in a hospital in Banepa, Nepal were examined for AFB₁ by enzyme-linked immunosorbent assay (ELISA).

2 This assay, previously validated using spiked sera, provides a sensitive rapid determination of serum aflatoxin (B₁, G₁ and Q₁).

3 All 28 sera were positive with concentrations from 60 pg ml^-1 to 10 ng ml^-1 .

4 These results suggest that consumption of aflatoxin in Nepal is high (> 50-800 ng kg ^-1 d^-1).

5 No reports of the degree of contamination of food, human consumption or body fluid concentrations of aflatoxin in Nepal have been previously published.

6 Aflatoxin may contribute to the development of hepatocellular carcinoma, which is probably a common tumour in Nepal.
