WASHINGTON - Investigators and retailers in eight states
and a territory are scrambling to recover meat that may have come
from a Holstein stricken with deadly mad cow disease.
Agriculture Department officials maintain, meanwhile, there is
no health risk to consumers.
Dr. Kenneth Petersen, a department veterinarian, said Sunday
that an investigation revealed that meat from the infected dairy
cow could have reached retail markets in Alaska, Hawaii, Idaho and
Montana and the territory of Guam - more locations than originally
thought.
Officials had said earlier that most of the meat went to
Washington and Oregon, with lesser amounts to California and
Nevada, for retail sale.
"The recalled meat represents essentially zero risk to
consumers," said Petersen, of USDA's food safety agency.
He said parts most likely to carry infection - the brain, spinal
cord and lower intestine - were removed before the meat from the
infected cow was cut and processed for human consumption.
Despite their assurances of food safety, federal officials have
taken the precaution of recalling 10,000 pounds of meat from the
infected cow and from 19 other cows slaughtered Dec. 9 at Vern's
Moses Lake Meat Co., in Moses Lake, Wash.
Because it is not known exactly what portions of the meat cut
that day came from the diseased cow, health authorities must assume
that some could have reached any location where any part of the
10,000-pound supply was distributed.
Officials still are recovering meat and won't know how much was
found for days, Petersen said.
Mad cow disease, known formally as bovine spongiform
encephalopathy, or BSE, is a concern because humans who eat brain
or spinal matter from an infected cow can develop a brain-wasting
illness, variant Creutzfeldt-Jakob disease. During a mad cow
outbreak in the 1980s, 143 people died of it in Britain.
Petersen said the slaughtered cow was deboned at Midway Meats in
Centralia, Wash., and sent Dec. 12 to two other plants, Willamette
Valley Meat and Interstate Meat, both near Portland, Ore.
Willamette also received beef trimmings, which were sold to some
three dozen small, mom-and-pop Asian and Mexican facilities in
Washington, Oregon, California and Nevada, officials said.
Several Western supermarket chains - Albertsons, Fred Meyer,
Safeway and WinCo Foods - have voluntarily removed ground beef
products from the affected distributors. Safeway has said it will
look for another supplier.
As the investigation continues, the list of countries banning
U.S. beef imports is growing. Jordan and Lebanon joined the list
Sunday. U.S. beef industry officials estimated earlier they lost 90
percent of their export market because of the bans by more than two
dozen nations.
U.S. agriculture officials in Tokyo tried to persuade Japanese
officials Monday to lift its ban. But Japan rejected the request,
saying officials should first establish the facts surrounding the
infection, a Japanese official said on condition of anonymity.
Japan is the largest overseas market for U.S. beef.
Officials with the World Organization for Animal Health
recommend countries shut down beef trade with any nation that has
mad cow.
Dr. Ron DeHaven, USDA's chief veterinarian, said research shows
that certain meats, such as beef steaks and roast, are safe from
infection. He said this suggests the trade restrictions "are not
well-founded in science."
Investigators have tentatively traced the first U.S. animal with
mad cow disease to Canada. This could help determine the scope of
the outbreak and might limit the economic damage to the American
beef industry.
The findings indicate the cow came from Alberta, the same
Canadian province where scientists found a single cow infected with
the illness in May. DeHaven and Canadian officials have stressed
that this still hasn't been confirmed because U.S. records
outlining the animal's history do not match those in Canada. DNA
tests will help resolve the matter.
Canadian documents show the cow had two calves in Canada,
contrary to U.S. records that said it had never produced calves
before it was shipped.
Also, Canadian documents said the diseased cow was 6½ years old,
but U.S. records said it was younger, around 4 to 4½.
The cow's age is significant because it may have been born
before the United States and Canada in 1997 banned certain feed
that is considered the most likely source of infection.
A cow can get sick from feed that contains brain or spinal
tissue of an infected animal. Farmers used to feed their animals
such meal to fatten them.
The Food and Drug Administration is investigating whether the
cow ate contaminated feed, but the animal may been infected years
before it appeared sick. BSE can incubate for four to five years.
It takes as little as half a gram of infected material to sicken
an animal, said Dr. Stephen Sundlof, head of the FDA's Center for
Veterinary Medicine.
Officials are less certain how much would infect a human, but
Sundlof said it would higher for humans than for cattle.
Investigators hope to soon determine whether the strain of BSE,
a disease caused by a misshapen protein, is the same one that
struck Europe, especially Britain, in the 1980s and 1990s.
