Antibiotic in Livestock May Pose Risk to Humans

Posted April 30, 2007

Consumer Reports

There is growing concern among researchers about a powerful antibiotic the Food and Drug Administration is expected to approve for treating sick cows. Some experts warn using the drug could pose a serious health risk for humans.

"What you put into your cattle makes a difference in what you take in as a human being," said Joyce Williams, a cattle farmer.

Joyce Williams, who is also a nurse, is one of many in the medical community, including the American Medical Association, concerned about the use of a strong antibiotic called Cefquinome.

"Cefquinome is a very powerful antibiotic that's best used as a last line of defense for serious illnesses in humans, particularly respiratory disease in children," said Michael Hansen, of Consumers Union.

The maker of Cefquinome wants the FDA to allow it to be used to treat sick cows. Hansen said overuse of the drug could produce "super bugs."

"This is very critical because there are a number of bacteria out there that literally are resistant to all antibiotics, save one or two," he said.

The danger of antibiotic-resistant bacteria getting into the food supply is very real. When Consumer Reports tested chickens last year for campylobacter and salmonella, the leading bacteria that causes food poisoning, testers found both bacteria on 83 percent of the chickens tested. Those tests also showed the bacteria were often resistant to one or more antibiotics.

Even within the FDA, there is controversy about the use of Cefquinome for sick cows.

"Last fall, the FDA's own scientific advisory panel recommended against approval for Cefquinome in cattle.," Hansen said. "This would be the first time that this class of powerful antibiotics has been approved for food-producing animals in the United States."

The FDA said if "credible scientific evidence" shows using an antibiotic in livestock "poses a health threat to people," the agency will take "every possible measure to protect human health." In the meantime, groups opposed to the use of Cefquinome in cattle vow to continue their fight!

Consumer Reports said the FDA appears to be ignoring lessons learned from the mid-90's when the agency approved a powerful new class of antibiotics for use in chicken feed. The drugs fight bacteria that can cause a diarrheal disease in people.

Soon after, doctors reported seeing antibiotic-resistant strains of bacteria in people hospitalized with severe diarrhea. Eventually, the FDA reversed itself and the drugs were withdrawn for use in chickens.

    Up for debate -
    Do the superbugs EVOLVE due to environmental pressures,
    or are they CREATED by God year after year?
    Talk amongst yourselves....

    It's not that the livestock harbor superbugs, constant exposure to antibiotic agents give the bacteria a change to become resistant. So in effect antibiotic use does create superbugs.

    But wouldn't the livestock have already had the super bugs in their system? The anti-biotics don't create the bugs, do they? It just means the bugs won't die, but they wouldn't before either, would they?

    I can't find cefquinome in my Physician Desk Ref. book on drugs. Be is as it may, many people are allergic to different antibiotics and anti-infectives. Some anti-infectives such a those derived from quinolones have side-effects that effect the mind. If you are getting sick after you eat, now you know why. Frequent exposure to antibiotics makes your body insensitive to them and you become resistent to them. If you get a serious infection, blood work may help to id what the infection is sensitive to but not what you are insensitive to. I haven't eaten beef in a long time. There are some good vegetarian websites to go to for alternatives. I'd recommend you check them out.

    This is the main reason that I stopped eating meat. Big corporations have now found a way to screw up living things to the point that they are bad for us now too. Thanks.

    What more proof do we need that our politicians are firmly in the pocket of the Big Pharmacuetical companies?
