Abstract:
The contamination of dairy products with various mycotoxins or other undesirable fungal metabolites can be attributed a.o. to ingestion of contaminated feed or the accidental development of molds and by consequence the excretion of fungal metabolites into the intermediate product. Different dairy products of commercial origin were examined: milk powder, reconstituted infant milk powder, and cheese. In addition to that, environmental factors contributing to the formation of the undesired fungal metabolites were studied. It was found that the presence of mycotoxins in dairy products is more related to the environmental factors causing mold growth on dairy products than to the ingestion of moldy feed by the cow.
