Abstract

By some recent estimates, mycotoxins affect as much as 25% of the world’s food crops each year. These highly toxic, naturally occurring compounds are by products (metabolites) of the growth of fungi or moulds. Mycotoxins can result in significant economic loss for crop producers and broiler producers since it represent an ongoing risk to profitability. Factors that contribute to mycotoxin contamination of food and feed include environmental, socio-economic and food production. Environmental conditions especially high humidity and temperatures favour fungal proliferation resulting in contamination of food and feed. The resulting implications include immuno-suppression, impaired growth, various cancers and death depending on the type, period and amount of exposure. Mycotoxin concerns have grown during the last few decades because of their implications to human and animal health, productivity, economics of their management and trade. This has led to development of maximum tolerated limits for mycotoxins in various countries. This paper highlights the use of naturally derived aflatoxin inhibitors from Azadirachtin compound of neem oil, and tray drying in controlling moisture content to inhibit the aflatoxin contamination in pretreated soy based animal feed. High moisture content found in soy based animal feed increases the risk of fungal growth during storage. Neem extract has shown potential as an effective feed additive to minimize the growth of fungi and possibly reduce the risk of toxic effects from mycotoxin production. Preservation methods by means of tray drying have also shown positive results towards the control of fungal growth.
