A multi-mycotoxin
method
based
on
High
Performance Liquid Chromatography coupled with tandem
Mass Spectrometry detection
(HPLC-MS
/MS)
was
applied to
investigate the
occurrence
of
toxic
fungal metabolites in
samples
collected
from
a poultry feed factory and integrated poultry
farms,
in
Brazil. A
total
of
119 samples
were analyzed including 38 maize grain samples collected from
the
factory reception, 36 maize grain samples and 9 maize
by-
product samples collected during the factory
processing, and 36 poultry feed samples collected from poultry
farms.
Twenty mycotoxins were
detected
and
quantified in
the
investigated samples: aflatoxins B
