livestock?

Introduc=on
Aflatoxins
are
hepatotoxic,
carcinogenic
and
immunosuppressing
metabolites
produced
by
moulds,
mainly
Aspergillus
flavus,
growing
on
maize
or
other
crops.
Humans
and
animals
can
get
acute
disease
with
fatali=es
as
well
as
chronic
disease.
• Aflatoxins
are
invisible,
tasteless
and
odourless,
and
can
be
present
in
a
wide
variety
of
crops
• When
animals
eat
the
toxin
they
can
get
sick,
and
they
are
less
produc=ve,
thus
producing
less
food
and
income
for
farmers
• Aflatoxins
are
metabolized
by
the
animals,
and
a
small
part
of
the
metabolites
is
present
in
animal
source
foods
Our
research
approach
and
ques=ons
What
are
the
levels
of
aflatoxin
in
marketed
crops
and
animal
feeds?
What
are
the
levels

aflatoxins

How
much
of
different

are
