Which of the following factors increases concern for mycotoxins?

• A. Certain weather patterns
• B. Insect damage
• C. Slow drying
• D. All of the above

Answer: (D)

Mycotoxin risk rises when conditions promote fungal growth and toxin production, and several factors contribute to that risk. Weather patterns that bring warmth and high humidity create an environment where fungi can colonize crops more readily, especially during flowering and pre-harvest periods. Insect damage provides openings in kernels or grains, giving fungi easier access and more sites to produce toxins. Slow drying leaves grains or products with residual moisture after harvest, extending the time fungi have to grow during storage. Because each of these factors independently enhances fungal activity and toxin formation, all of the factors listed increase concern for mycotoxins.
