The influence of drought on the occurrence of aflatoxins in maize
In this study, a total of 78 maize samples harvested during September and October 2012 in Vojvodina were analyzed. Presence of aflatoxins (AFs) was determined by enzyme-linked immunosorbent assay (ELISA) method. Among the 78 analyzed maize samples, even 44 (56.4%) samples were contaminated with AFs. Concentration interval between 1-10 μg/kg, 10-50 μg/kg and 50-80 μg/kg were found in 23.1%, 17.9% and 15.4% of analyzed maize samples, respectively. It was supposed that prolonged drought during spring and summer of 2012 had a great influence on high contamination frequency and concentration of AFs.

PRESENCE OF AFLATOXINS IN CEREALS FROM SERBIA
ABSTRACT: Aflatoxins (AFs), one of the most toxic and the strongest natural carcinogens can be found in a variety of food commodities, including cereals. For that purpose, the aim of this study was to investigate occurrence of AFs (AFB1, AFG1, AFB2 and AFG2) in 130 cereal samples
Mycotoxins in maize: Annual variations and the impact of climate change
The presence of aflatoxins (AFs), ochratoxin A (OTA), zearalenone (ZEA),
deoxynivalenol (DON), and fumonisins (FUMs) was examined in maize samples
from the Republic of Serbia. The maize samples were collected during the
period 2012-2016, and analyzed every year after harvest using validated
Enzyme Linked Immunosorbent Assay (ELISA) method. The obtained results were
considered regarding the weather conditions parameters recorded during the
investigated maize growing seasons. Significant differences in
weather-related parameters recorded in the five-year period resulted in
different mycotoxin profiles between the investigated years. Obtained
results indicate that the presence of ZEA and DON in maize is characteristic
of years with abundant precipitation, while AFs and OTA mainly occur in
maize during hot and dry years. Furthermore, FUMs were detected with
different contamination frequency in maize samples from every year. Based on
the findings obtained in this study, as well as on noted changes in weather
conditions in the recent years it could be assumed that maize from Serbia
may become susceptible to problems concerning mycotoxins. Therefore, there
is a necessity for monitoring and research related to the mycotoxins
occurrence in maize from Serbia
