How do diseases damage grain?

• A. Fungi produce toxins that can cause illness and death if consumed.
• B. Insects are the sole cause of disease damage.
• C. Diseases only affect color.
• D. Healthy grain is immune to disease.

Answer: (A)

Diseases damage grain primarily through fungal pathogens that produce toxins, or mycotoxins, which can contaminate the grain and cause illness or death in people or animals if consumed. These toxins can be present even when mold isn’t obvious, and many are heat-stable, meaning cooking or processing may not remove the hazard. In addition to toxin production, fungal infections also cause physical damage to kernels—rot, shriveling, and reduced weight or germination—leading to lower yield and quality. Environmental conditions like warm, humid weather and stressed crops increase both fungal growth and toxin production, making proper drying, storage, and monitoring essential. Insects can cause damage too, but they’re not the sole cause of disease damage, and disease-related changes aren’t limited to color or limited to supposedly “healthy” grain being immune.
