The primary sources of mycotoxins that can potentially contaminate beer include contaminated malt or adjunct grains used in malting and brewing. Australia typically has a dry climate during barley harvest that results in dry barley for storage. However, screening for quality assurance purposes is still required because of the unlikely event of barley infection by fungal species, from which harmful mycotoxins can accumulate. Quality control protocols require that malting barley be free of mycotoxins such as deoxy- nivalenol (DON) and ochratoxin A (OTA). Immunoaffinity columns (IACs) are widely used to isolate mycotoxins from barley, malt, and feed, followed by quantification by either HPLC or fluorometry. Mycotoxin analysis procedures are relatively easy to use, rapid, accurate, and toxin specific, but expensive. The repeated reuse of DON and OTA IACs assists in reducing the cost of mycotoxin analysis without compromising safety, especially when the occurrence of these mycotoxins is rare, such as with Australian malt and barley. © 2009 American Society of Brewing Chemists, Inc.
