How do you remove aflatoxin from corn?

Field drying and mechanical drying were found most effective for controlling Aflatoxin contamination in maize. A Rapid BGYF test was developed to estimate Aflatoxin levels and is being used by many maize dealers. Chemicals were tested for controlling the causal fungi.

How does aflatoxin affect ears of corn in a field?

flavus can also attack corn in the field. Field infection of corn by A. flavus can result in aflatoxin production in the corn before harvest. The fungus is able to invade through the corn silks or in association with insect damage to kernels and ears.
