Reducing the Impact of Aflatoxins in Livestock and Poultry Preventing Aflatoxin and Other Mycotoxin Contamination in Feedstuffs

چکیده
Mycotoxin contamination of feed ingredients impart considerable economic costs stemming from cost of preventative and mitigation practices, reduced value of contaminated feeds, contamination of foods of animal origin and reduction in animal performance and health. Therefore, much research has sought to find methods to overcome these issues. Currently, the best procedure is to minimize mycotoxin production as well as animal exposure to mycotoxins. In line with this, good management practices (in the field, at harvest, at storage) may significantly reduce the contamination of feed and the intoxication of animals (Table 1). However, even with excellent management there may be small amounts of mycotoxins which are unavoidable. These low concentrations are a constant concern for potential loss of feedstuffs, increased animal disease, reduced animal performance and residues in animal products. Importantly, many countries (such as is the case with aflatoxin in the U.S. per U.S. Food and Drug Administration) generally do not permit grains containing mycotoxins to be blended with uncontaminated grains, in order to reduce the mycotoxin content of the resulting mixture to levels acceptable for use as human food or animal feed. However, on occasion the FDA has relaxed its “no-blending” policy in response to widespread outbreaks of aflatoxin (AF) or to state-specific requests to address local outbreaks (as was allowed in Indiana during the 2012 harvest).
