Ways of milk contamination with mycotoxins, harmful effects of mycotoxins, as well as the possibilities for decontamination of mycotoxin contaminated milk are presented in this paper. The research results of efficacy of absorption of aflatoxins M1 and M2 in yoghurt by natural and modified zeolite (clinoptilolite) are presented. In laboratory conditions, two amounts of both absorbents (0.2 and 0.6%) with and without addition of sodium caseinate were applied. It was determined that both absorbents had high efficiency for aflatoxin M1 and M2 absorption. The efficiency was higher without addition of sodium caseinate, and absorption of both aflatoxins was slightly higher on modified zeolite. Compared with lower amount of absorbents (0.2%), the higher amount of both adsorbents (0.6%) showed higher adsorption of aflatoxin M1 and M2. The sedimentation of absorbents in yoghurt was not observed.
