excessive rainfall and stored high-moisture corn have favored the growth of storage 

 arid secondary molds (fungi) . 



When working in enclosed areas, such as bins, maintain adequate ventilation- -turn 

 on fans 15 minutes before entering a closed area, and wear a suitable dust mask and 

 spore -protecting respirator. Dr. Harvey Hirning, UI Extension Agricultural Engineer, 

 has a list of masks and respirators that are commercially available. 



Clean empty storage bins thoroughly, and disinfect them with liquid household bleach 

 (Clorox, Purex, Sunny Sol) by spraying the surfaces with a solution of one part bleach 

 in four or five parts of water. Wear a respirator and rubber gloves. Keep the spray 

 from contacting your clothing or skin. 



The storage molds most likely to be encountered are Penioillium spp. and Aspergillus 

 spp. This information may be useful if you consult a doctor about respiratory ill- 

 ness. We can analyze dust samples to determine which molds are present, but indi- 

 viduals differ greatly in their sensitivity to the wide range of molds found in grain 

 storage areas. 



Molds cause about 15 percent of all human allergies. It is better to take precau- 

 tionary steps than to try and solve the problem after it occurs. :
