BSE: "DOWNED" ANIMALS, CROSS-SPECIES TRANSMISSION
"The cow went down and that's why it was shipped. It was still alive. It
was just not getting up anymore." {1} So explained the farmer of the
Canadian cow found to be infected with BSE (see N.17, V.2). He said she
couldn't stay standing and was trucked to slaughter.{2} A meat inspector
reported that the cow looked thin and had pneumonia.{3} Ten feed mills
received parts of her rendered body, some of which was processed into chicken
feed and dry dog food {4} (some of which may have been sent to the U.S.) {5}
While giving feed containing ruminant remains to cattle is illegal, some 60
cows from 3 different farms that received the feed were ordered to be
slaughtered since it could not be confirmed that they had not been given it.
{6} So far, 18 farms have been quarantined {7} and over 1,160 cattle
have been killed for testing {8}. Due to inconclusive findings, another 650
cattle are to be tested. {9} Five bulls from a herd the infected cow had
been in were sent to Montana in 1997. {10} The bulls were used for
breeding purposes {11} and are thought to have spent 1-3 years at the same
operation prior to having been sent to stockyards in Montana and South Dakota.
{12} They are believed to have been slaughtered after the ban on the use
of cattle in ruminant feed. {13}
NONAMBULATORY ANIMALS: It is unknown how many nonambulatory animals
("downers") enter the Canadian food chain. {14} Animal Alliance of
Canada, an animal protection organization, obtained government documents
showing that in 1999 in Ontario, 639 sick cattle were approved for slaughter.
Additional records were available for only 358 of them, of which 316 were
slaughtered for human consumption. The others were sent to rendering to be
made into animal feed and other products. {15} The government has a code
of practice that says that sick, injured, or disabled cattle in severe
distress should be euthanized or slaughtered on the farm and not trucked to
slaughter. However, the federal code is merely suggested practice with no
regulatory force. {16} The Canadian Cattlemen's Association guidelines also
recommend that nonambulatory cattle not be sent to slaughter. {17}
Nonambulatory cattle are, however, allowed to be chained and dragged from
transport vehicles to slaughter. {18}
In Canada, as in the U.S., cattle showing classic symptoms of BSE (e.g.,
staggering) are to be tested for it. {19} But an animal who does not exhibit
these signs and merely appears thin or listless -or exhibits no symptoms at
all- could still have the disease.{20} Infected cattle usually don't
exhibit disease symptoms for about 5 years but are typically slaughtered at
about 30 months of age. {21} Sylvie Farez, a veterinarian with the
Canada Food Inspection Agency, says there are too many nonambulatory animals
at slaughterplants to be able to test them all. {22} According to
Consumer Union's Michael Hansen, only 3,337 Canadian cattle were tested for
BSE among the 3.5 million who were slaughtered in 2002. {23} In the
U.S., only about 3,300 of an estimated 55,000 nonambulatory cattle were
tested. {24} (Other sources put the number of nonambulatory cattle at
195,000 to 1 million.) {25} A total of 19,900 cattle were tested for BSE
in the U.S. in 2002, up from 5,272 in 2001 {26} [out of an annual slaughter
total of about 35,000,000]. A 2001 German study found that nonambulatory cows
were 10-240 times more likely to test positive for BSE than ambulatory cows.
{27} In Canada, about 2% of cattle are slaughtered in places that are
not federally licensed and have no federal inspector present. {28}
Regarding both Canada and the U.S., animal scientist and industry consultant
Temple Grandin remarked: "You've got dairymen out there, they don't have
to worry about cleaning up their downers. They take them to the
slaughterhouse, and though less and less slaughterplants want them -your big
plants just don't accept downers anymore- you've got smaller plants that are
getting to be a niche market of downers....There will always be certain
restaurants that'll buy that stuff." {29} The USDA is considering
banning all nonambulatory cattle from being used for human consumption (see
issue #53), and has already banned its own procurement agency from purchasing
the meat from these animals. {30}
CROSS-SPECIES TRANSMISSION: About 44% of the 1 million cattle who die prior to
slaughter are rendered. {31} Elk and deer with chronic wasting disease (CWD),
a similar disease, are also processed into animal feed. {32} (In the
U.S., some 50 billion pounds of animal bone, skin and other tissue are
processed into meat meal, bone meal and other products each year.) {33} While
both Canada and the U.S. have prohibited the use of most ruminant remains in
ruminant feed since 1997, they are still used in feed for chickens, pigs and
other nonruminant animals who are thought not to be susceptible to the
disease. {34} (It is believed that prions, the agents considered
responsible for BSE, have not been found in ruminant blood, fat, milk and
gelatin, which is still allowed in ruminant feed.) {35} These animals can then
be killed and used in ruminant feed. {36} There is concern that they may
serve as unaffected carriers of the disease. {37} (The surprising
results of cross-species infection experimentation can be found in a June 3rd
New York Times article entitled "Mad Cows, Sane Cats," at:
http://www.nytimes.com/2003/06/03/science/03SPEC.html
) Due to related disease concerns, the FDA has proposed limits on the use of
deer and elk in dog and cat food. {38}
Gleaning the Canadian Food Inspection Agency regulations, a Vancouver Sun
reporter notes they are "evidence that just about anything can go into
animal feed if it will make somebody a penny." {39} One example he
gives is the use of stomach and intestinal contents of pigs and poultry in the
making of feed for ruminants. {40} Similarly, U.S. regulations permit
the use of poultry manure and litter in animal feed. {41} A researcher
with the U.N.'s Food and Agriculture Organization (FAO) defends the use of
manure in animal feed, writing that "Feeding of animal wastes results in
reducing feed costs and a lower price of animal products." {42}
Others defend rendering as an economic and ecological way of utilizing
material that would otherwise have to be buried or incinerated. {43}
Because prions can withstand the intense heat used in the rendering process,
{44} animal remains in farmed animal feed have been banned in Britain since
1996 and in the European Union since 2000. {45} (Thousands of British
cattle born after a ruminant-to-ruminant feed ban exhibited BSE symptoms.)
{46} Additionally, feed tends to stick to machinery and
ruminant-inclusive feed can commingle with ruminant-exclusive feed if
processed at the same facility or transported in the same trucks. {47}
It is estimated that 44,000 British cattle were infected with BSE because of
this. {48} Prohibited feed can also be illegally fed to ruminant
animals, intentionally or unintentionally. {49}
CHANGES & COMPARISONS: Canadian officials are now considering changing the
regulations that allow ruminant remains to be used in chicken and pig feed.
{50} The USDA is also considering additional safeguards against BSE, including
the handling of nonambulatory animals:
