Animal Feeds Mycotoxins and Risk Management

Abstract

The demand for livestock products is the main factor affecting the demand for livestock feeds worldwide. However, animal feed safety has gradually become more important, with mycotoxins representing one of the most significant hazards. Mycotoxins are toxic secondary metabolites produced naturally by fungi that grow on various agriculture commodities. Aflatoxin, fumonisin, ochratoxin, trichothecene, and zearalenone are the more prevalent mycotoxins in animal feeds. Some of mycotoxins impacts include; loss of animal and human health, reduced animal productivity, increased veterinary service costs, feed disposal and increased research costs which enhance the importance of mycotoxins detoxification. Contamination of feeds may occur both during pre-harvest and post-harvest. The purpose of this chapter is to review the most prevalent mycotoxins in animal feeds, reveal the origin of mycotoxins contamination and the possible risks they pose to feeds and livestock. This chapter also gives an overview of the most important factors that influence mold growth and mycotoxin production as well as the economic impacts of mycotoxins. To the end of this chapter, mycotoxins preventive methods, both preharvest and postharvest, are well discussed.
