| Research Abstract |
We measured the concentrations of aflatoxins in Bolivian red chili pepper, and then determined whether aflatoxin-contaminated red chili pepper consumption is the cause of the development of gallbladder cancer. Aflatoxin B1 was detected at concentration of 11.3 ppb from 1 sample. However the concentrations of several red chili peppers were less than the detection limit of our analysis method. Since our findings suggest that the low-level but protracted exposure to aflatoxins may be associated with the development of gallbladder cancer, further studies, such as investigation of the background of contaminants, are needed.
