Abstract: Prevention of mycotoxins in cereal encompasses prevention of toxin biosynthesis and metabolism in the field or instorage.Mycotoxin detoxification refers to post-harvest treatments to remove,destroy,or reduce the toxin effects.Failure toprevent mytoxin formation in the field or in storage inevitably will lead to an increased health risk and economic loss.However,successful monitoring should prevent mycotoxin from vecoming a significant source of increased health risk.An integrated multi-pronged approach is the preferred strategy for controlling mycotoxin contamination.The pr-harvest or post-harvest strategythat should be emphasized will be dependent on the climatic conditios of that particular year.Understanding the environmentalfactors that promote infection,growth ,and toxin production is the first step towards an effective plan to minimize mycotoxinsin foods and feeds.There are many new and exciting pre-harvest prevention strategies being esplored that involve production ofgenetically engineered resistant cereal.Biocontrals using non-toxigenic biocompetitive agents is also a potentially useful strategyin cereal.Post-harvest prevention of mycotoxin production is primarily dependent on good management practicesbefore harvestand after harvest detoxification strategies that are physical,chemical,or microbiological can detoxify cereal by destroying,modifying,absorbing the mycotoxin so as to reduce or eliminate the toxic effects.
