Arsenic in chicken feed may pose health risks to humans, C&EN reports
Pets may not be the only organisms endangered by some food additives. An arsenic-based additive used in chicken feed may pose health risks to humans who eat meat from chickens that are raised on the feed, according to an article in the April 9 issue of Chemical & Engineering News, the weekly news magazine of the American Chemical Society.
Roxarsone, the most common arsenic-based additive used in chicken feed, is used to promote growth, kill parasites and improve pigmentation of chicken meat. In its original form, roxarsone is relatively benign. But under certain anaerobic conditions, within live chickens and on farm land, the compound is converted into more toxic forms of inorganic arsenic. Arsenic has been linked to bladder, lung, skin, kidney and colon cancer, while low-level exposures can lead to partial paralysis and diabetes, the article notes.
Use of roxarsone has become a topic of increasing controversy. A growing number of food suppliers have stopped using the compound, including the nation抯 largest poultry producer, Tyson Foods, according to the article. Still, about 70 percent of the 9 billion broiler chickens produced annually in the U.S. are fed a diet containing roxarsone, the article points out.
Complicating the issue is the fact that no one knows the exact amount of arsenic found in chicken meat or ingested by consumers who frequently eat chicken. 揘either the Food and Drug Administration nor the Department of Agriculture has actually measured the level of arsenic in the poultry meat that most people consume,?according to the article.
The National Chicken Council, a trade association that represents the U.S. chicken industry, claims there is 搉o reason to believe there are any human health hazards?associated with the use of roxarsone. 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领 Arsenic in chicken feed may pose health risks to humans, C&EN reports
鸡饲料中的砷可能对人类的健康造成威胁
Pets may not be the only organisms endangered by some food additives. 宠物可能不是唯一受到某些食品添加剂威胁的生物。 An arsenic-based additive used in chicken feed may pose health risks to humans who eat meat from chickens that are raised on the feed, according to an article in the April 9 issue of Chemical & Engineering News, the weekly news magazine of the American Chemical Society.根据美国化学会每周出版的新闻杂志《化学化工新闻》4月9日期所刊登的一篇文章，一种用于鸡饲料的含砷添加剂可能会对那些食用用饲料饲养的鸡的鸡肉的人的健康造成威胁。
Roxarsone, the most common arsenic-based additive used in chicken feed, is used to promote growth, kill parasites and improve pigmentation of chicken meat.洛克沙胂是在鸡饲料中最常用的含砷添加剂，被用于促生长，杀灭寄生虫及改善鸡肉的颜色。 In its original form, roxarsone is relatively benign.洛克沙胂当以原形药物存在时，相对是良性的。 But under certain anaerobic conditions, within live chickens and on farm land, the compound is converted into more toxic forms of inorganic arsenic.但在某些缺氧的情况下，在活鸡体内及农场中，该化合物可被转化成毒性更大的无机砷形式。 Arsenic has been linked to bladder, lung, skin, kidney and colon cancer, while low-level exposures can lead to partial paralysis and diabetes, the article notes.该文章称，砷与膀胱癌、肺癌、皮肤癌、肾癌及结肠癌有关联，而低浓度的暴露能导致局部瘫痪和糖尿病。
Use of roxarsone has become a topic of increasing controversy.洛克沙胂的使用已经成为一个争议越来越多的话题。 A growing number of food suppliers have stopped using the compound, including the nation抯 largest poultry producer, Tyson Foods, according to the article.文章称，越来越多的食品供应商已经停止使用这一化合物，包括美国最大的禽类生产商Tyson食品公司。 Still, about 70 percent of the 9 billion broiler chickens produced annually in the U.S. are fed a diet containing roxarsone, the article points out.但是，文章指出，美国每年生产的90亿只肉鸡中，仍然有大约70%使用含洛克沙胂的饲料喂养。
Complicating the issue is the fact that no one knows the exact amount of arsenic found in chicken meat or ingested by consumers who frequently eat chicken.使问题更显复杂的是，没有人知道鸡肉中所含的砷或是经常吃鸡肉的消费者所摄取的砷的确切数量。 揘either the Food and Drug Administration nor the Department of Agriculture has actually measured the level of arsenic in the poultry meat that most people consume,?according to the article.文章称，美国食品与药品监督管理局及农业部都未对许多人都消费的禽肉中所含的砷水平进行检测。
