Some parts of the country have received a lot of moisture this fall and harvested grain has moisture greater than 15%. This figure came to mind as I read the article, “Watch for Mycotoxins“. Two years ago we had a rush of samples with a locally wet fall harvest. Mycotoxin analysis is critical in detecting potential fungal growth and toxin production. According to the articel, 13 percent moisture or less is iedal to limit further fungal growth.
The article notes some issues to be aware of with respect to mycotoxins. (Source Kansas State University Extension swine specialists: Mike Tokach and Joel DeRouchey)
- Clean the grain before storage, remove damaged kernels
- Consider adding propionic acid to corn before it goes into storage
- Monitor grain bin temperatures as hot spots will increase fungal growth and toxin production
- Segragate corn into high- and low-mycotoxin level bins if possible
If you suspect any presence of mycotoxins, have your grain tested by a laboratory that actually tests mycotoxins using the latest technology by LC/MS. You will know that you are getting an accurate analysis to a specific level.
