How does moisture control influence mycotoxin risk during storage?

• A. Moisture control has no impact on mycotoxins
• B. Proper drying and moisture control reduces mold growth and mycotoxin production
• C. Higher moisture always reduces mycotoxins
• D. Moisture controls only bacteria, not mycotoxins

Answer: (B)

Controlling moisture is a primary way to limit mold growth and mycotoxin formation during storage. When feed or grains stay damp, molds such as Aspergillus and Fusarium can colonize the material and produce mycotoxins as they metabolize. Drying to a safe moisture level and keeping storage conditions dry lowers the water activity available to fungi, slowing or stopping their growth and toxin production. Proper moisture management, including thorough drying, adequate venting, and monitoring humidity, directly reduces the conditions that allow mycotoxins to form. The other statements miss this link: moisture does impact mycotoxin risk, higher moisture does not lessen risk, and moisture control affects fungi (the producers of mycotoxins), not only bacteria.
