Significance of trichothecene mycotoxins in poultry feed
Marijana Sokolović
Sažetak
Sanitarily healthy animal feed of optimal quality is an essential prerequisite for animal health and productivity as well as for contamination prevention of human food. The development of ever more sensitive detection methods and the discovery of noxious effects of mycotoxins has incited increased attention to the assessment of the risk that mycotoxins present for human and animal health. With this purpose, many investigations on mycotoxin prevalence in feed and on economical and clinical impacts of various toxins in animals have been conducted. The growth of yeast on cereals is a common occurrence, and grain quality and environmental conditions (temperature, oxygen and carbon dioxide concentrations, humidity in the air and in the feed) determine the level of mycotoxin contamination of the feed. Based on the reports of completed investigations, not only regulations are being introduced on maximal permitted quantities of harmful substances in feed, but also guidelines with the recommended mycotoxin levels are being developed, all with the aim to act in accord with good manufacturer's practice. The occurrence of mycotoxins in nature due to frequent importations and exportations is considered a global problem. It has been observed that in particular parts of the world particular mycotoxin groups develop. In countries with moderate climates, as, for instance, in Canada, northern parts of North America and in Europe, the greatest problem are fusarium mycotoxins and ochratoxin A. Aflatoxin, whose development is precipitated by humid climates (South America, some Asian, African and Australian regions) is a problem in other parts of the world only when cereals are imported from these regions. As trichothecene mycotoxins, along with other numerous adverse effects on poultry health, also have impact on production results, and as their development is encouraged by climate conditions in the Republic of Croatia, this mycotoxin group is exceptionally important in Croatia, notably for poultry production.
