Nivalenol and Aflatoxin B in malt for beverages - A major supplier of malt was concerned that a new source would not be able to meet their strict requirements for quality. As part of their QA program, the supplier sent EMSL samples to determine if any mycotoxins were present. The lab was able to quickly develop an extraction and analytical method in one week using LC/MS/MS giving the supplier the needed conformity to allow the use of the new malt.
