Abstract
Mycotoxins are toxic compounds produced by certain types of fungi that can contaminate animal feed. Cattle may be exposed to these toxins through contaminated feed sources such as cereal grains (e.g., corn, barley), silage, hay, and other roughages, where aflatoxins, fumonisins, T-2 toxins, zearalenone, deoxynivalenol, ochratoxins, and emerging mycotoxins are most commonly found. Cattle are generally less sensitive to mycotoxins, mainly due to detoxification processes occurring in the rumen. The rumen plays a key role in the degradation or transformation of mycotoxins through the activity of ruminal microorganisms and enzymes before these toxins are absorbed into the bloodstream. However, despite this natural defense, mycotoxins have been shown to impact ruminant health. This article aimed to analyze the literature on the negative effects of mycotoxin exposure on cattle health. In January 2025, a systematic search of various databases (PubMed, Google Scholar, EMBASE, and Web of Science) was conducted in Google Chrome to identify studies assessing the association between mycotoxin exposure and health complications in cattle. Symptoms of mycotoxin poisoning are nonspecific and include metabolic and hormonal imbalances, inflammatory conditions, weakened immune response, digestive disorders, reduced productivity, and reproductive issues. These toxins may also compromise the safety of the food chain, including the quality of milk and meat products. Due to the increasing risk of mycotoxin contamination in feed, a comprehensive approach to feed management is essential. This includes regular monitoring, proper storage of raw materials, and the use of plant protection products that minimize the risk of contamination.
