Abstract
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin using ultra-performance liquid chromatography coupled to tandem mass spectrometry. Mycotoxin concentrations were further interpreted according to known species-specific sensitivities and normalized according to the principles of [...]

Mycotoxin concentrations were further interpreted according to known species-specific sensitivities and normalized according to the principles of toxic equivalent factors expressed in μg kg−1 of aflatoxin B1-equivalent
The toxins identified in total mixed ration (TMR) were fumonisins, trichothecenes A, trichothecenes B, fusaric acid, aflatoxins, and ergot
Summary
Mycotoxin contamination occurs in many materials, including animal feed, animal products, and soil. As these toxins affect animal production and health, they can cause substantial economic losses. Factors that can affect the production of mycotoxin by fungi include abiotic factors, such as temperature and humidity, and biotic factors, such as fungal load at the time of transportation and storage. As the presence of these mycotoxins relates to specific environmental conditions and type of material, the characteristics of contamination could vary regionally. The trading of ingredients among regions, countries, and continents could play a role in the contamination dynamics and change mycotoxins distribution patterns
