A new superbug



'Worse than AIDS' - sex 'superbug' discovered in Japan called disaster in waiting
Doctors are warning that a drug-resistant strain of gonorrhea could be more deadly than AIDS, and are urging members of US Congress to spend $54 million for the development of a drug that would fight it.

"This might be a lot worse than AIDS in the short run because the bacteria is more aggressive and will affect more people quickly," Alan Christianson, a doctor of naturopathic medicine, told CNBC.

The new strain of gonorrhea, H041, was first discovered in 2009 after a sex worker fell victim to the superbug in Japan. Medical officials reported that the medication-resilient ‘sex superbug’ was discovered in Hawaii in May 2011, and has since spread to California and Norway, the International Business Times reports.

Nearly 30 million people die from AIDS-related causes each year, and the H041 superbug could have similar consequences, according to Alan Christianson, a doctor of naturopathic medicine.

"Getting gonorrhea from this strain might put someone into septic shock and death in a matter of days,"Christianson said. "This is very dangerous."

The gonorrhea strain has not yet claimed any lives, but the US Centers for Disease Control and Prevention (CDC) have asked Congress for $54 million to find an antibiotic to treat the strain.

In a Capitol Hill briefing last week, health officials said an education and public awareness campaign is crucial in minimizing the effective of HO41. William Smith, executive director of the National Coalition for STD Directors, said that if the ‘sex superbug’ spreads, it could quickly kill many people before a treatment is discovered. And that risk becomes increasingly more likely if Congress does not provide the funds to find a cure, he said.

"It's an emergency situation. As time moves on, it's getting more hazardous," he told members of Congress.

"We have to keep beating the drum on this," he added. "The potential for disaster is great."

In the United States, there are 20 million new STD infections each year, which results in about $16 billion in medical costs, the CDC reports. More than 800,000 of these cases gonorrhea infections, most of which occur in young people ages 15 to 24. Gonorrhea is sometimes difficult to detect, since it shows no symptoms in about half of all women. Those who fall ill to the deadly strain may not notice it until it’s too late.

That’s what’s kind of scary about this,” Smith said.

Although health officials have widely reported that cases of H041 were discovered in California, Hawaii and Norway, the CDC has disputed those claims and told CNBC on Monday that the infection has not been confirmed anywhere outside of Japan. The CDC did, however, make an announcement in 2011 that it was noticing greater gonorrhea bacterial resistance to certain types of antibiotics in Hawaii and California. 

CDC officials said that the US and Norwegian cases were treated effectively with antibiotics not routinely recommended and that these cases were mistakenly identified as H041. But the agency continues to urge Congress for research funding, indicating that the risk of infection is high regardless of where the cases occurred.

Christianson is urging people to practice safe sex and get STD tests if they are in a new relationship, since a superbug infection could be around the corner.

"This is a disaster just waiting to happen," he told CNBC. "It's time to do something about it before it explodes. These superbugs, including the gonorrhea strain, are a health threat. We need to move now before it gets out of hand."

The logical result of industrial farming


Are You Eating 'Superbugs?' Resistant Bacteria Found At Alarming Rates On Meat In Stores


16 April, 2013

There is a lot of talk these days about how feeding antibiotics to livestock is resulting in ‘superbugs’ – bacteria resistant to drug treatment in humans and animals.

But do consumers really need to be concerned about eating meat they buy at the grocery stores?

A new report released today by the Environmental Working Group (EWG) says, yes.

The group analyzed 2011 data recently released by the U.S. government and found 81 percent of ground turkey and 55 percent of ground beef sold in supermarkets carried antibiotic-resistant strands of salmonella and Campylobacter. Together these bacteria cause 3.6 million cases of food poisoning a year. More than half of all chicken sampled carried antibiotic-resistant E. coli.

Almost 90 percent of all store bought meat also had signs of normal and resistant Enterococcus faecium – a bacteria that indicates the product came in contact with fecal matter at some point during or after processing.


Even if the idea of a little diarrhea or a urinary tract infection does not faze you (both of which can be caused by E. coli), the problem is that as strains of antibiotic-resistant bacteria become more commonplace in our lives, the less we are able to use the drugs to treat common human diseases.

The Center for Disease Control (CDC) and 11 other government departments including the Food and Drug Administration and the National Institutes of Health reported in 2012:

Antimicrobial resistance (AR) is not a new phenomenon; however, the current magnitude of the problem and the speed with which new resistance phenotypes have emerged elevates the public health significance of this issue….Since their discovery, antimicrobials have been used extensively in livestock and poultry for the treatment, control, and/or prevention of animal diseases, as well as for production purposes… The impact of increases in resistant bacteria in food animals on the management of human infections is an ongoing concern as many classes of antimicrobials used in food-producing animals have analogues to human therapeutics and are therefore capable of selecting for similar resistance phenotypes.

What the CDC report did not mention is that many involved in the livestock industry like the American Meat Institute, the International Egg Commission, and the Animal Health Institute (whose membership includes Bayer, Merck, and Mars) reject these concerns. They also hold enormous power over legislators and committee members.

In other words, if we continue to buy these meats, it is likely industry will continue to use antibiotics to raise animals. But by doing so, we will put our own health, and the health of the global population, at risk.

So how to stay away from these contaminated meats?

Yes, you could cook the hell out of your hamburger to keep you and your family safe from contamination.

But you could also eat better raised meat (and less of it).

An estimated 8.9 billion animals a year are raised in confinement where cramped conditions, a lack of exercise (or fresh air), and high stress environment necessitate the use of antibiotics. These animals are also fed “subtherapeutic” doses of the drugs in their feed to promote faster growth and to make them susceptible to the rampant diseases caused by jamming too many animals into one facility.

Alternately, if you purchase organic meats or those raised without antibiotics, bacteria has not had the exposure to the drugs to develop resistance. Less cramped conditions also mean less disease, and processing only a few animals at a time allows for more care and less contamination of meats. Several stores, like Whole Foods, have a great selection of meats raised without any antibiotics. (See this infographic and post for more information on where to buy meats raised without antibiotics.)

Or, you could stop eating meat.
