| dc.description.abstract | Background: Multi-mycotoxin exposure is a frequent and significant problem,
since swine feed is based on different type of cereals, which may contain huge
variety of mycotoxins.
Surveys all over the world have shown the presence of 2 or more mycotoxins at
the same time in cereals and other feed materials. In the last 20-25 years the
multi-mycotoxin studies received more attention.
Objectives: The aim of the study was the multi-mycotoxin monitoring survey of
Hungarian swine feed samples, based on raw materials harvested in 2019, 2020
and 2021.
Materials and Methods: In this study concentrations of more than 800 mycotoxins and metabolites were determined from swine complete feed samples
(representing feed for weaned and growing piglet, fattening pig under 65 kg,
fattening pig between 65 and 90 kg, pregnant sow and lactating sow). The measurement was performed by a validated LC-MS/MS method.
Results and Discussion: For 132 mycotoxins and metabolites detectable concentration values were measured. The recommended values or the regulation
limit of European Union (574/2011/EU; 2013/165/EU; 2006/576/EC) were not exceeded
in any cases. Data have been compared to relevant international surveys. In the
DSM (earlier BIOMIN) World Mycotoxin Surveys higher concentrations of various
mycotoxins in feed materials (such as corn, wheat, barley, soy or triticale) were
found and Hungary was classified as a high risk region. In our study in case of
fumonisins and deoxynivalenol (DON) the recommended risk threshold of DSM
were exceed in 2021. Based on the recommendation published by the Section of
Agricultural Sciences of the Hungarian Academy of Science, all the samples we
examined fall into the low risk range. Among the emerging mycotoxins, moniliformin (MON), beauvericin (BEA) and enniatins (A, A1, B, B1) were present in most
cases in concentrations above the limit of determination (LOQ). | en_US |
