Arsenic in More than Juice?

1 comment

In my last post, I highlighted the presence of arsenic in fruit juice and the need to be vigilant when it comes to what we feed ourselves and our families. In response, one reader offered the following comment which underscores the problem with another staple food item – chicken:

Bret, bravo on sharing information about arsenic. I just wish the spotlight were being put on chicken too, as it has even more arsenic than apple juice. (Reason: because arsenic is actually put in the chickens' feed.) See Dr. Greger's column (I recommend NutritionFacts.org as an excellent site for nutrition info. It's non-commercial, and it provides sources for all research cited.)

I decided to follow-up and look into the matter, and Jennifer is correct.

On June 8,2011, the FDA issued a press release highlighting that Pfizer, Inc, announced that its subsidiary, Alpharma, would voluntarily suspend U.S. sales of its animal drug Roxarsone. Here's what the FDA said:

The U.S. Food and Drug Administration today announced that Alpharma, a subsidiary of Pfizer Inc., will voluntarily suspend U.S. sales of the animal drug 3-Nitro (Roxarsone), a product used by poultry producers since the 1940s.

The move follows a recent FDA study of 100 broiler chickens that detected inorganic arsenic, a known carcinogen, at higher levels in the livers of chickens treated with 3-Nitro compared with untreated chickens. FDA officials stress that the levels of inorganic arsenic detected were very low and that continuing to eat chicken as 3-Nitro is suspended from the market does not pose a health risk.

“FDA detected increased levels of inorganic arsenic in the livers of chickens treated with 3-Nitro, raising concerns of a very low but completely avoidable exposure to a carcinogen,” said Michael R. Taylor, FDA deputy commissioner for foods. “We are pleased to announce that the company is cooperating with us to protect the public health.”

Arsenic is in the environment as a naturally occurring substance or as a contaminant and is found in water, air, soil, and food. Published scientific reports have indicated that organic arsenic, a less toxic form of arsenic and the form present in 3-Nitro could transform into inorganic arsenic. In response, scientists from the FDA’s Center for Veterinary Medicine and the Center for Food Safety and Applied Nutrition developed an analytical method capable of detecting very low levels of inorganic arsenic in edible tissue.

Using the new method, FDA scientists recently found that the levels of inorganic arsenic in the livers of chickens treated with 3-Nitro were increased relative to levels in the livers of the untreated control chickens.

Alpharma decided to voluntarily suspend sale of 3-Nitro and to facilitate an orderly process for suspending use of the product in the United States. Alpharma’s plan provides for continued sales of 3-Nitro for 30 days from today. The company stated that allowing sales for this period will provide time for animal producers to transition to other treatment strategies and will help ensure that animal health and welfare needs are met.

In addition, the company is working with the FDA to examine all relevant scientific data regarding the use of 3-Nitro in animals.

Nitro became the first arsenic-containing new animal drug product approved by the FDA. It is used primarily in broiler chickens. Combined with other animal drugs, 3-Nitro has been used by some in the poultry industry to help control coccidiosis, a parasitic disease that affects the intestinal tracts of animals. It has also been used for weight gain, feed efficiency and improved pigmentation.

FDA has consulted with the U.S. Department of Agriculture and is working with Alpharma to minimize the impact on the animal agriculture industry as 3-Nitro is suspended from the market.

Of course, reactions to these findings and this development vary depending on perspective:

"Arsenic in chicken production poses a risk not only to human health, but to the environment," said Michael Hansen, a senior scientist with Consumers Union, which publishes Consumer Reports. "We need to get arsenic out of food production altogether."

The National Chicken Council, which represents companies that produce and process chickens, said in a statement that the ingredient has been used to maintain good health in chickens for many years, and that it is used in "many, but not all" flocks.

"Chicken is safe to eat," the group said.

Perhaps industry advocates protest too much. Why are sales only being suspended in the United States? Don't consumers in other countries deserve the same protections and, supposedly, safe food sources as those of us who happen to live in the U.S.? Of course they do. We all need to join voices into one as we call for a safe food supply no matter where we live.

    Bret,

    I work for Maryland State Delegate Tom Hucker who has been working to ban roxarsone from poultry feed for three years. Based on your last post, I wanted to point out that because of FDA’s study, Canada recently banned the feed-additive nationwide, and it has been banned in the European Union for over ten years. We have some more information on our website at http://www.tomhucker.com/arsenic if you’re interested or email us at Tom@TomHucker.com.
