February 17, 2002 Facing criticism that the use of antibiotics
in chicken feed actually was
allowing disease- causing bacteria in humans to develop a resistance
to these same antibiotics
major poultry producers in the US slowly have begun adjusting
their chickens' diets. While it
long has been believed that antibiotics in chicken feed resulted
in healthier, larger
chickens, Tyson Foods, Perdue Farms and Foster Farms have all
begun taking most or all
antibiotics out of their chicken feed. Furthermore, the poultry
producers are not using a
specific antibiotic used to treat sick birds because it is related
to Cipro, which is used to
treat anthrax in humans.
While fear of anthrax has not been high on radar screens in
recent years, fears of terrorist attacks on the food supply have
made manufacturers and retailers highly sensitive to anything
that might impact effective treatment of the disease. Some corporate
consumers, including McDonald's, Wendy's and Popeye's, reportedly
are refusing to buy chickens that have been fed or treated with
antibiotics. SupermarketGuru.com believes that this is a good
move on the part of manufacturers; concerns of consumers about
any sorts of antibiotics that might result in "super germs"
almost impervious to treatment are greater and more relevant
than ever. From the consumer perspective, it is accurate to say
that the general population just wants to get rid antibiotics
in food, soaps, etc., and that they don't even want to deal with
the discussion. Just get rid of them and be done with it.
That's pretty much the way things are going, because retailers,
restaurants and manufacturers largely have been mum about this
significant shift in approach. In this case, however, retailers
and
manufacturers may not want to follow the consumer's lead, because
lack of communication about
important health issues like these is usually not the right move.
Eventually, something
happens -- and then consumers say things like, "Why didn't
you tell me?" Looking back at the
consumer and saying, in the immortal words of Jack Nicholson,
"You want the truth? You can't
handle the truth!" will not engender much trust. The problem
isn't communicating about issues.
It is the fact that most retailers and manufacturers don't communicate
with consumers about
issue on a regular, credible basis. Communication becomes reactive
the problems, and often
defensive. Instead, communication needs to be open, credible,
and routine.
By making it part of the everyday conduct of business, this communication
will create business-to-consumer relationships that are equally
honest and business-as-usual. Besides, it makes sense for retailers
and manufacturers to stay in front of issues like these. While
there have been
reductions in the use of antibiotics in feed, the US Food and
Drug Administration (FDA)
suggests that the level of resistance to bacteria caused by overuse
of antibiotics is
unacceptable. An outright ban may be in the works, and it is
entirely possible that politics
could enter the fray. If that happens, retailers and manufacturers
better make sure they are
not only on the right side of the issue, but that they have practiced
full disclosure and
cannot be criticized for hidden or deceptive practices. Now read
how the same data appeared in
Time Magazine, under "Medications and Prevention How To
Stay Healthy In 2002." http://www.time com/time/covers/1101020121/antibiotics.html
Playing Chicken With Our Antibiotics
Overtreatment
is creating dangerously resistant germs By Christine Gorman
It's the sort of thing any good
poultry farmer notices right away: a few of the birds in a so-called
grow-out building have
started snickering ­ the chicken equivalent of coughing.
A respiratory infection, if that's
what they have, could spread to the 20,000 other birds in the
chicken house in a matter of
days. The vet recommends the antibiotic enrofloxacin ­ the
animal version of Cipro. Since it's
not practical to treat the birds individually, the farmer pours
a 5-gal. jug of the drug into
the flock's drinking water. Five days later the birds are doing
fine. Disaster has been
averted. Or has it? While enrofloxacin kills the type of bacteria
that sickened the chickens,
it doesn't quite eliminate a different strain, called Campylobacter,
that lives in the
intestine.
The surviving germs, which don't cause any poultry diseases,
quickly multiply and spread the genes that helped them fend off
the antibiotic. Six weeks later, when the broilers are carved
up at the slaughterhouse, resistant bacteria spill out everywhere.
Even with the best sanitary controls, some campylobacter is shrink-wrapped
along with the thighs, breasts and drumsticks that are delivered
to your kitchen counter. That's where the real trouble begins.
Campylobacter is a major cause of food poisoning in humans. Less
than diligent hand washing or improperly cooked meat could park
you on the toilet for the next few days. And if you're sick enough
to need medical treatment, you might be out of luck.
Chicken Cipro is so closely related to human Cipro that any
germ that has become resistant to the animal drug can shrug off
the human one just as easily. Before 1996, when enrofloxacin
was approved in the U.S. for use in poultry, the number of Campylobacter
infections in people that were resistant to Cipro and its chemical
cousins was negligible. By 1999, it had jumped to 18% ­ a
clear sign, many researchers argue, that at least part of the
increase is directly tied to the use
of antibiotics on poultry farms. Welcome to the harrowing world
of antibiotic resistance,
where drugs that once conquered everything from pneumonia to
tuberculosis are rapidly losing
their punch. Chicken Cipro is only the latest example of how
humans are burning their
pharmacological bridges. Feed-lot operators are dosing their
livestock with antibiotics to
keep them healthy under stressful growing conditions. Parents
are demanding the most powerful
broad-spectrum agents, often by brand name, for their children's
upper-respiratory infections.
Consumers are snapping up cutting boards, dishwashing soap
and baby toys laced with
antibacterial compounds, hoping to make their homes perfectly
sterile and safe. Doctors have
long understood that the indiscriminate use of antibiotics usually
backfires, selecting for
germs that are tough to kill. But no one was prepared for how
easily resistance could spread
even when the drugs were used in what was thought of as appropriate
treatment. You may be
among those who do not believe that some strains of bacteria
are able to transfer DNA . Well,
heres how it was printed up in Time magazine . .
The problem is that bacteria share genetic information much
more readily than anyone thought. Individual cells ­ often
from different species ­ routinely exchange tiny loops of
dna called plasmids. They will even pick up snippets of DNA from
dead bacteria or viruses. Once a strain of bacteria survives
destruction by antibiotics, chances are it will eventually pass
on the genes for resistance to other germs. "It's a numbers
game," says Dr. Stuart Levy, a Tufts researcher and author
of The
Antibiotic Paradox. And because they live everywhere and reproduce
quickly, bacteria have the
upper hand. It doesn't help matters that many Americans have
come to think of antibiotics as
tools for prevention.
Patients will often ask for the drugs to keep their colds from
turning into sinus infections, even though antibiotics have no
effect on the viruses that cause colds in the first place. What's
harder to evaluate is the treatment of something like a middle-ear
infection, which is indeed caused by several different types
of bacteria, including Pneumococcus. Left alone, a handful of
these infections could lead to permanent hearing loss.
And yet their treatment has, in just the past 10 years in
the U.S., boosted the prevalence of
penicillin-resistant pneumococci to more than 20%. No one yet
advocates allowing all bacterial
infections to run their course. But don't be surprised if your
doctor takes more of a wait-
and-see approach with your next case of flu (which, like a cold,
is caused by viruses).
Hospitals are also learning how to vary the drugs they give their
patients to diminish the
chances of selecting for ever more resistant germs. Relief may
soon be on the way. Thanks to
advances in the new science of genomics, researchers have started
to scour bacterial DNA for
new and possibly better targets for drug development. The goal
is to produce a compound that
works so differently from today's antibiotics that germs won't
know how to start developing
resistance.
Other research has produced drugs that help restore penicillin's
ability to clobber resistant germs, provided the compounds are
given in combination. In the meantime, the FDA is so concerned
about the possibility of losing Cipro and similar drugs that
it has asked pharmaceutical companies to stop selling them to
poultry farmers. Bayer, which manufactures both Cipro and enrofloxacin,
is contesting the idea, arguing that resistance levels have stabilized
and can be managed. The question remains: How much resistance
are you willing to live with? Most infections you get that are
drug resistant came to you drug resistant," Levy says.
You can do your part to halt their spread by not taking antibiotics
unnecessarily and following a doctor's orders when they are prescribed.
Saving pills for later, so you don't have to get a new prescription,
is definitely a bad idea. "We'll be in this business for
a long time to come," says Dr. Stephen Lory, professor of
microbiology and molecular genetics at Harvard Medical School.
"We will come up with something; bacteria will become resistant.
We'll come up with something new. It's the kind of contest where
no matter how hard you fight, the best you can hope for is a
draw. And now . . . the rest of the story, from the report .

Health in Maryland By Sean Dobson and Carl Kandutsch Progressive

According to the CDC, in more than one-third of the salmonella-poisoning
cases in 1997, the
bacteria were resistant to five antibiotics used to treat the
disease. Moreover, staph bacteria, which cause skin, blood, heart
valve, and bone infections that can lead to septic shock and
death, are becoming increasingly resistant to the chief antibiotic
that has been used to treat them, methicillin. From 1975 to 1991,
the incidence of methicillin-resistant staph bacteria in U.S.
hospitals increased from 2.4 percent to 29 percent.2 The CDC
has concluded that antimicrobial use in food animals is the dominant
source of antibiotic resistance among food-borne pathogens in
the United States. The American Medical Association recently
adopted a resolution (AMA Resolution #508) calling for a ban
on such use.
The scope of the public health issue at stake is amply demonstrated
by the sheer volume of antibiotics used for animal growth. The
Union of Concerned Scientists estimates that livestock producers
in the United States use 24.6 million pounds of antimicrobials
in the absence of disease for nontherapeutic purposes; approximately
10.5 million pounds in poultry, 10.3 million pounds in
hogs, and 3.7 million pounds in cattle. This figure represents
a dramatic increase in the
nontherapeutic use of antimicrobials for animal growth since
the mid-1980s, when about 16.1
million pounds were so used. This increase has been driven primarily
by the poultry industry,
which increased its use of antibiotics by an astounding 307 percent
over the last fifteen
years.(3) Marylands Eastern Shore is one of the largest
poultry producing areas in the United
States.
According to Delmarva Poultry Industry, Inc., during year
2000 Maryland produced 283.3
million broilers, ranking seventh among poultry-producing states.
The major farms in Maryland
include Tyson Foods, Inc. (number 1 in the nation), Perdue Farms,
Inc. (number 4), Mountaire
Farms, Inc. (number 9) and Allen Family Farms, Inc. (number 16).
All of these producers
administer massive quantities of human-used antibiotics to poultry
for nontherapeutic
purposes. By contrast, only about 3 million pounds of antimicrobials
are used in human
medicine each year, one-eighth the quantity used for the nontherapeutic
treatment of animals.
The Union of Concerned Scientists estimates that nontherapeutic
livestock use accounts for 70
percent of total antimicrobial use.(4) And the more antibiotics
agribusinesses use, the more
likely that bacteria will become resistant. The Antibiotic Reporting
Act (Senate and House
versions) was referred to the Senate Economic and Environmental
Affairs Committee. Supporters
of the Antibiotic Reporting bill included members of the public
health and scientific
communities, as well as environmental groups (especially the
Sierra Club). At the Committee
hearing, the bill was opposed by several powerful industry groups,
including the Maryland Farm
Bureau, the Animal Health Institute, Delmarva Poultry Industry,
Inc., the Maryland Pork
Producers and the Maryland Grange and Dairy Farmers Association.
Despite receiving a favorable vote from the Senate Committee
and despite Sen. Hollingers outstanding record of successfully
moving legislation, the bill was voted down on the Senate floor
by a two-to-one margin. Follow the Money Trail How could such
a common-sense bill fail to pass? The question becomes less perplexing
when we look at the deep pocket special interests opposed to
it. The Maryland Farm Bureau is state chapter of the American
Farm Bureau Federation (AFBF). While purporting to represent
family farmers, the AFBF is in fact a coalition of agribusiness
interests (including insurance, banking and factory-farming,
for example), which takes in more than $200 million each year
in membership dues. A major player in the U.S. Congress, AFBF
can certainly take care of its interests in the smaller arena
of the Maryland General Assembly. (5)
- The Animal Health Institute is a coalition of pharmaceutical
and related companies, including the Bayer Corporation. Bayers
Animal Division, based in Kansas, dominates the market for animal-feed
floroquinolones with a drug called Baytril, and has strongly
opposed the FDAs proposal to ban that class of antibiotics
from subtherapeutic uses as well as numerous state efforts to
reduce nontherapeutic livestock use ­ or even to study the
issue. The Animal Health Institute (AHI) was represented in the
Maryland General Assembly by its national Executive Director,
a fact
that demonstrates the importance of the antibiotic reporting
issue to the animal
pharmaceutical industry. In fact, a visit to AHIs website
(http://www.ahi.org/New_Welcome.htm) shows that defusing the
entire issue is among the organizations highest priorities;
the
website is replete with various studies and "fact sheets"
highly critical of any effort to
question the subtherapeutic use of antibiotics for animal growth.
-
For the AHI, its a questionof the bottom line: Of the fifty
million pounds of antibiotics produced every year in the United
States, 40 percent of that is given to animals, and 80% of what
is given to animals is used to promote their growth. (6) Were
poultry producers to change their antibiotic feeding practices,
the result could be that AHI member companies such as Bayer would
lose a very
significant market for its product. Delmarva Poultry Industry,
Inc. (DPI), is a tri-state
trade association representing large poultry producers (and related
interests) on the Eastern
Shore. DPI has long been very active and powerful in the Maryland
General Assembly, employing
some of the states highest paid professional lobbyists.
-
- Those lobbyists include Gerard Evans (now in jail for defrauding
clients), William Satterfield, Michael Canning as well as George
and Nicholas Manis. Agribusiness and pharmaceuticals contributed
a total of $554,819 to all candidates for Maryland office in
the 1998 election cycle, targeting $132 052 to candidates for
the Senate. A single pharmaceutical interest group ­ the
"Pharm PAC" family of PACS ­ all by itself contributed
$27,980.
And A Closing Note From The University of Southwestern Medical
School at Dallas, 1998. A
dangerous bacteria makes it more important than ever to be careful
about how you handle
poultry. The bacteria called Campylobacter (Kam-PY-lo-back-ter)
is believed to infect about 70
to 90 percent of all chickens. This bacteria causes an illness
similar to that caused by
salmonella, another bacteria known to infect poultry. People
with Campylobacter infection may
have severe diarrhea, abdominal pain stomach cramps and fever.
The bacteria also can trigger
Guillain-Barre syndrome, a paralyzing illness. Salmonella causes
more illness and death than
Campylobacter, but Campylobacter is beginning to cause concerns
because the bacteria appears
to be developing a resistance to the antibiotics usually used
to treat infections caused by
it.
To prevent illness caused by bacteria in poultry, it's important
that you handle poultry
properly. Thaw poultry in the refrigerator rather than at room
temperature. Wash any surface
that comes in contact with raw poultry with hot water and antibacterial
cleanser. Don't use
the same utensils you used on raw poultry with cooked poultry.
Cook poultry thoroughly. Use a
meat thermometer to make sure the poultry has reached a safe
internal temperature
Doctors at UT Southwestern Medical Center at Dallas say cooking
stuffing inside a chicken or
turkey can be risky. You're better off cooking the stuffing in
a separate pan so it doesn't
get contaminated by bacteria from the poultry. ­ # ­
