Another Reason Not to Eat Factory Chicken: Arsenic

By RP Siegel

Earlier this week Nicholas Kristof wrote a piece in the NY Times about arsenic in chicken. He cited two studies that gave evidence of arsenic, caffeine, Tylenol, Benadryl and certain banned antibiotics in chicken.

The two studies, conducted by the Johns Hopkins Center for a Livable Future, and Arizona State University set out to look for the presence of antibiotics in chicken, but they found much more than that. “We were kind of floored,” said study co-author Keeve E. Nachman. “It’s unbelievable what we found.”

While they did not find anything that they felt was an “immediate health concern,” you have to wonder what the long term effects of ingesting these things might be.

You might think this is all a bunch of chicken feed, but really, how did these things get in there? Clearly, it was no accident. It turns out that arsenic has routinely been fed to livestock to reduce infections. It also tends to make the flesh a more appealing color and enhance growth. What with the use of arsenic as well as thousands of tons of antibiotics, enough to put all of us at risk from the development of resistant strains, it pretty clear that infections are a major problem on these overcrowded meat factories, which are now being regulated to avoid this problem in Europe.

As to the studies’ methodology, since farmers are not required to disclose what they feed their animals, and they have become so protective of their secrecy that they have successfully lobbied for a law that makes it illegal to photograph a factory farm operation in some states (not that they have anything to hide, mind you), the researchers had to resort to indirect tactics. They analyzed feathers which, like fingernails, accumulate chemicals found in the body. Specifically, they purchased and analyzed feather meal, a poultry byproduct that can be used as fertilizer or as livestock feed. That’s right, they feed the feathers back to the chickens. How else do you expect to get chicken for $2.99 a pound? It would cost a lot more if they gave them real food.

Tom Super, vice president of the National Chicken Council, tried to minimize the findings. “As the study’s authors point out, this study looked only at feathers, not meat. If consumers were to take away one message from the findings, it should be from the researchers themselves: ‘We haven’t found anything that is an immediate health concern.’"

Super went on to say that, “Chickens in the United States produced for meat are NOT given ‘arsenic’ as an additive in chicken feed, or any of the other compounds mentioned in these studies.”

However, he did point out that, “Some flocks used to be given feed that contained a product called Roxarsone, which included organic arsenic – not the inorganic form that is considered a poison.  This product, however, was removed from the market last year.”

According Tom Philpott, writing in Mother Jones, sales of Roxarsone which is also a growth enhancer, were voluntarily discontinued by its manufacturer, Pfizer, “after FDA tests found traces of the poison in chicken meat.”

Roxarson had been used for decades after WWII, with industry assurances that the organic arsenic was far less toxic than the inorganic form routinely used as poison. However, more recent findings discovered that the arsenic in Roxarsone would, under certain conditions, such as in the intestines of a chicken, shift to the far more toxic form, which, according to Food and Water Watch “is associated with increased risk for several kinds of cancer, including bladder, kidney, lung, liver and prostate.” It is also associated with increased risk of cardiovascular disease, diabetes, and neurological problems in children.

In response to these concerns, the use of arsenic in chicken feed was recently banned by the Maryland General Assembly.

Perhaps more disturbing than the arsenic was the discovery of illegal antibiotics in the samples. Specifically, fluoroquinolones, a class of broad spectrum antibiotic, including Cipro, that are used in people with infections that have become resistant to older antibiotics. These were found in 8 of the 12 samples collected in the multi-state study. The use of these antibiotics in poultry was banned in 2005 by the FDA in response to increasing signs of antibiotic resistance in Campylobacter bacteria. It will be difficult if not impossible to eliminate this dangerous microbe if these antibiotics are being administered to chickens on such a wide scale.

In addition to arsenic and Cipro, the samples were also found to contain caffeine, acetaminophen, the antihistamine diphenhydramine (the active ingredient in Benadryl) and the antidepressant fluoxetine (the active ingredient in Prozac).

Americans eat more meat than any other people and more chicken than any other meat. The average American consumes 100 pounds of chicken per year.

The researchers are recommending that the FDA monitor the feed that is given to livestock.
