Sažetak

The possibility of using luminescent microorganisms Photobacterium phosphoreum (strain IMB B-7071; Sq3) for rapid toxicological evaluation of feed contaminated with mycotoxins was examined based on the reduction of the luminescence intensity. Under the conditions of this study, feed with Ochratoxin A mycotoxin content at the level of maximum residue limits (MRL 0.05 mg/ kg) is characterized as non-toxic, while for T2-mycotoxin, deoxynivalenol, fumonisins and aflatoxin B1 (MRL 0.1, 1.0, 5.0, and 0.01 mg/kg, respectively) is characterized as toxic, and for zearalenone (MRL 1.0 mg/kg) as highly toxic. This indicates the need for further research to study the toxicological characteristics of mycotoxins in the body of laboratory and productive animals, possibly with further revision of the maximum allowable levels of relevant contaminants in feed in Ukraine.
