IMPORTANT INFORMATION ON THE
FEEDING OF ANIMAL BY-PRODUCTS
|
Bovine
Spongiform Encephalopathy (BSE)
The
opinion of the European Commission's
Scientific Steering Committee (SSC) of
27-28 November 2000 on the feeding of
animal proteins to ruminants and
non-ruminants and measures to minimize
the risks of contamination is summarised
as follows:
"In view
of the arguments that might support
continuing feeding of mammalian proteins
to non-ruminants and the
cross-contamination issue, the SSC
recommends that, if recycling of animal
material as feed to animals is applied,
measures that reduce the risk to recycle
[BSE]-infectivity are implemented. These
include:
-
In any
country where the BSE risk [is
'unlikely but not excluded'], no
ruminant-derived feed should be fed to
ruminants;
-
In
countries [where] BSE [has been
'confirmed at a higher level'], no
ruminant - or other BSE-susceptible
animal - derived meat and bone meal
should be used as feed for mammalian
animals and a total feed ban to all
farmed animals and pets should be
considered. For the other species
(fish and poultry), the
recommendations listed in the next
paragraph, should apply.
For
countries with geographical BSE risk
levels [that are 'unlikely but not
excluded' or 'likely but not confirmed
or confirmed at a lower level'], the
following recommendations are valid:
-
Only
raw materials as listed in the SSC
opinion of 24-25 June 1999 on
"Fallen stock" are acceptable for
recycling;
-
All
recycled animal protein material
should be treated [by autoclaving
at] 133° for 20 minutes at 3bars
[pressure] or equivalent conditions
because this would reduce any
infectivity by a factor of at least
1000;
-
Appropriate slaughtering methods
should be applied, to avoid possible
distribution of infectious material
to other parts of the body that are
subsequently rendered while SRM
[Specified Risk Materials] are
excluded;
-
Not
only cross-contamination of ruminant
feed with ruminant protein should be
avoided but also cross-contamination
of non-ruminant feed with high-risk
material (SRM). Possibly
contaminated materials stored since
before a MBM [Meat and Bone Meal]
feed ban should be carefully
removed.
-
A
number of additional recommendations
are made in the SSC opinion of 17
September 1999 on the risk born by
recycling animal by-products as feed
with regard to propagating TSE in
non-ruminant farmed animals.
Tallow, gelatin, dicalcium phosphate
and hydrolyzed proteins should be
produced under appropriate
conditions, as defined in the SSC
opinions, as this will effectively
reduce infectivity entering their
production;
What
precedes implies that the SSC -
provided that all the above
preventive measures recommended are
implemented properly - does not
necessarily advocate banning feeding
of animal materials to non-ruminant
farm animals or pet animals, even in
countries were the presence of BSE
cannot be excluded, is likely or is
confirmed at a lower level. With
respect to BSE/TSE matters, the SSC
repeatedly stated that its opinions
are only valid provided the
recommended measures, including
those regarding cross-contamination,
are properly implemented. Should the
risk assessment carried out by an
interested country show that this is
not the case for a certain period of
time, a temporary total MBM feed ban
would be the most effective approach
to stop the propagation of the
disease."
