(2022): Analysis of Mycotoxin and Secondary Metabolites in Commercial and Traditional Slovak Cheese Samples
TOXINS. 2022; 14(2), 134 FullText FullText_BOKU

Abstract:
Cheese represents a dairy product extremely inclined to fungal growth and mycotoxin production. The growth of fungi belonging to Aspergillus, Penicillium, Fusarium, Claviceps, Alternaria, and Trichoderma genera in or on cheese leads to undesirable changes able to affect the quality of the final products. In the present investigation, a total of 68 types of commercial and traditional Slovak cheeses were analyzed to investigate the occurrence of fungal metabolites. Altogether, 13 fungal metabolites were identified and quantified. Aflatoxin M1, the only mycotoxin regulated in milk and dairy products, was not detected in any case. However, the presence of metabolites that have never been reported in cheeses, such as tryptophol at a maximum concentration level from 13.4 to 7930 mu g/kg (average: 490 mu g/kg), was recorded. Out of all detected metabolites, enniatin B represents the most frequently detected mycotoxin (0.06-0.71 mu g/kg) in the analyzed samples. Attention is drawn to the lack of data on mycotoxins' origin from Slovak cheeses; in fact, this is the first reported investigation. Our results indicate the presence of fungal mycotoxin contamination for which maximum permissible levels are not established, highlighting the importance of monitoring the source and producers of contamination in order to protect consumers' health.
