Bioassay of mycotoxins using terrestrial and aquatic, animal and plant species

The role of bioassay in the diagnosis of mycotoxicoses in farm animals is discussed. Methods for detecting mycotoxin contamination of animal feeds using biological species (aquatic and terrestrial animals and plants but excluding bacteria and yeast) are reviewed. Factors that need to be considered when choosing and using particular bioassay procedures in a feed-screening programme are discussed in relation to the occurrence of false positives and false negatives.
