Which action is a recommended preventive measure against aflatoxin contamination in feed?

• A. Purchase feed from reputable suppliers experienced in aflatoxin prevention
• B. Store feed at very high moisture levels
• C. Increase dust accumulation in milling areas
• D. Ignore storage bin leaks

Answer: (A)

Aflatoxin contamination is best prevented by starting with a reliable, tested supply chain. Molds that produce aflatoxins thrive when feed is stored in warm, moist conditions, so keeping moisture low and maintaining good storage practices is essential. The strongest preventive action is to buy feed from reputable suppliers who actively prevent aflatoxin contamination through routine testing, quality assurance programs, and traceability. This helps ensure that contaminated lots are not entering the feed system and that any issues are detected early.

Other options would raise risk or do little to stop contamination. Storing feed with very high moisture creates an ideal environment for mold growth and toxin production. Increasing dust in milling areas can spread contaminants and indicate poor housekeeping, while ignoring leaks in storage bins lets moisture and contaminants seep in, promoting mold and toxin formation.
