Aflatoxins were not detected either the inoculated green or roasted regular beans. Small amounts of aflatoxin (0.30 ¿g/g) were detected in roasted decaffeinated samples, while high levels of aflatoxins (up to 60 ¿g/g) were detected in green decaffeinated samples. A sample of commercially decaffeinated green coffee beans was also found to support the production of aflatoxin. The data indicate that extra precaution should be employed to assure the safety of decaffeinated coffees
