Abstract

Aflatoxins are secondary metabolites
of toxigenic moulds of the Aspergillus species.
Aflatoxin M₁, a metabolite of the potent carcinogen aflatoxin B₁
(AFB₁) occurs in milks of animals consuming feed contaminated with
AFB₁. The aim of this study was to investigate the occurrence and
levels of aflatoxin M₁ (AFM₁) in UHT milk samples
consumed in Burdur city markets. In 2018, a total of 78 UHT milk samples were
randomly collected from different markets of Burdur. The occurrence and
contamination levels of AFM₁ in the samples were investigated by the
competitive enzyme-linked immunosorbent assay (ELISA) method. Aflatoxin M₁
was detected in 24 of 78 samples (30.77 %) in concentrations between
4.30-127.44 ng/L (mean level: 47.54 ng/L). AFM₁ levels in 11 of
these 24 positive samples were above legal limits of Turkey which is 50 ng/L
for milk samples. It is concluded that the occurrence of AFM₁ in
milk samples in particular may be considered as a possible hazard for public
health.
