Mycotoxins. Contemporary issues of food animal health and productivity.

Modern agriculture and production animal medicine require attention to high-quality feeds that are free from mycotoxin contamination that can cause economically important decreases in productivity. Maintaining current information about effects of mycotoxins on feed intake and growth, reproductive efficiency, and possible immunosuppression aid in effective consultation with livestock producers. Investigation and determination of potential production losses related to mycotoxins should use historical, clinical, laboratory, and experimental information to objectively evaluate whether mycotoxin contamination is clinically relevant. The practicing veterinarian or veterinary consultant can provide valuable clinical and interpretive assistance to producers who may have a real or potential mycotoxin contamination. Thorough diagnostic evaluation of animals, appropriate testing of feeds and forages, and rational consideration of differential diagnoses help to put mycotoxins in the proper perspective as a production-related management problem.
