• Aflatoxin is our reality this year, and we urge dairy producers to be informed! Legal limits of aflatoxin are being enforced: No more than 20 parts per billion are allowed in dairy cow feed, and no more than 0.5 parts per billion are allowed in milk!
• Ultimately, it is up to the dairy farmer to make certain that he/she are within the allowable limits.
• When drying corn this fall, dry at 180 degrees or higher, dry quickly to 14% moisture to minimize the aflatoxin growth.
• We have heard of problems with Illinois corn producers who used low heat bin dryers. Avoid it! Low heat drying may give the mold the conditions it needs to produce a lot of toxin very quickly. Stirraters may even make things worse, mixing up and spreading the mold.  
• If aflatoxin is a problem in your neighborhood, do not use drying bins of any type to dry the corn.  Do not store wet corn in trucks, bins, anywhere for more than 24 hours.    
• From an aflatoxin growth perspective the corn is better off in the field than in wet storage.
• Consult your crop insurance agent prior to harvesting if you know you have issues with aflatoxin.
