Previous studies have shown that the contamination of milk
and dairy products and variations in the concentrations were related
to geographic position, national development level and season
(Tajkarimi et al., 2008; Çelik et al., 2005). In small farms
(extensive production), in spring and summer there is fresh animal
feed available such as pasture, grass, weeds and raw feed. However,
in cold months dry prepared feed or concentrates are used
much more often. Also, animals are frequently fed with dry hay
which in inadequate storage conditions may lead to appearance
of aflatoxin producing moulds and aflatoxins (Heshmati & Milani,
2010; Kamkar, 2005; Tajkarimi et al., 2008). It is suggested that
the most effective way of controlling AFM1 in the food supply is
to reduce contamination with AFB1 of raw material and supplementary
feedstuffs for dairy cattle with good manufacturing practice
and good storage practice
