Occurrence of aflatoxin M1 in raw cow, goat and sheep milk during spring and autumn in Croatia during 2016

Abstract

Raw cow, goat and sheep milk samples were collected in different regions of Croatia during spring and autumn 2016. Aflatoxin M1 (AFM1) concentrations were measured in the following ranges (ng/kg): cow milk 0.93–85.4; goat milk 2.0–18.6; sheep milk 2.27–11.2. AFM1 levels exceeding the European Union maximum residue levels of 50 ng/kg were found in two cow milk samples in spring and 10 cow milk samples in autumn. The probable daily intakes (PDIs) for all three dairy species were from 0.0108 to 0.0165 ng/kg b.w./day and contributing 1.08–1.65% to the proposed provisional maximum tolerable daily intake (PMTDI; 1 ng/kg b.w./day), indicating low risk exposure for consumers. The mean positive cow milk PDI was 0.15 ng/kg b.w./day, contributing 15.2% to the PMTDI.
