【08.11.29】美国FDA公布婴儿奶粉中三聚氰胺容忍标准
【星岛网讯】在美国知名品牌婴儿奶粉被发现含有微量三聚氰胺后，美国食品及药物管理局（FDA）今天公布婴儿奶粉中可容忍的三聚氰胺标准，并表示消费者可持续安心食用美国制婴儿奶粉。据中央社报道，十月初，FDA曾提出婴儿奶粉以外产品三聚氰胺2.5ppm以下含量无害的报告，但报告表示，由于设立标准的许多不确定性，他们对婴儿奶粉无法建立一个他们认为不会引起健康顾虑的三聚氰胺标准。
不过，在美联社披露FDA在美国知名婴儿奶粉中测试出三聚氰胺相关成分后，FDA今天公布，婴儿奶粉中的三聚氰胺或三聚氰酸，个别不超过1ppm“不会引发公共健康忧虑”。
FDA食品安全官员桑德洛夫（Stephen Sundlof）表示，他们对设立这个标准有信心。他也说，FDA调查仍显示国内婴儿奶粉安全，消费者可持续使用美国制婴儿奶粉。
但他也指出，FDA无法对三聚氰胺与三聚氰酸同时出现，设立安全标准。目前研究显示，三聚氰胺和其衍生物三聚氰酸同时出现，产生结晶物，才会对健康造成较大威胁。
在中国毒奶粉事件传出后，FDA曾表示美国制婴儿奶粉管制严格，美国市场受核准可配销婴儿奶粉的制造商，并未从中国进口原料，他们确信一般市面上英文包装的婴儿奶粉没有问题。
不过，他们之后测试了87种样本的婴儿奶粉产品，在已分析的74种结果中，发现了雀巢Good Start强化补铁婴儿奶粉含微量三聚氰胺，美琼森（Mead Johnson）Enfamil LIPIL补铁婴儿奶粉含微量的三聚氰酸。
另一家婴儿奶粉公司亚培大药厂（AbbottLaboratories），则是在内部测试中发现微量三聚氰胺。这三家婴儿奶粉制造商的产品占了美国市场约九成。
和中国污染事件不同的是，专家认为，这些微量的污染物是在食品处理过程出现，并非蓄意添加；桑德洛夫也表示，三聚氰胺可能在食品包装过程中渗入，而三聚氰酸则是一种清洁剂成分。
但他也坦言，FDA无法解释为何三聚氰胺和三聚氰酸只出现在某些样本中。“我不想揣测为何一些样本有，一些样本没有”，“真正的答案是，我们不知道”。 美國的可以容忍？？？ FDA sets 'safe' levels for melamine in baby formula

(CNN) -- After first saying that they could not determine a threshold for the safe amount of certain toxic chemicals in infant formula, Food and Drug Administration officials said Friday that trace amounts are safe.
"Amounts of the industrial chemical melamine or the melamine-like compound called cyanuric acid that are below 1.0 ppm do not raise public health concerns," said Stephen Sundlof, the FDA's director of the Center for Food Safety and Applied Nutrition.
When it became known in September that thousands of babies in China had been sickened by tainted infant formula, the FDA ordered the testing of U.S.-manufactured infant-formula products.
Sundlof said Friday that results from 74 of 87 samples of infant formula and other products babies and young children had been completed. The results of the other 13 are pending.
That total differed slightly from the one the FDA offered Thursday, when its acting commissioner of public affairs, Judy Leon, told CNN that 77 sample results had been completed and just 10 were outstanding.
Among the 74 final test results discussed Friday, the FDA said, two samples of Nestle's Good Start Supreme Infant Formula with Iron tested positive for melamine at levels of 137 and 140 parts per billion, well below the level of concern cited by Sundlof.
In addition, three samples of Mead Johnson's infant powder, Enfamil LIPIL with Iron, tested positive for cyanuric acid at an average of 247 parts per billion, also well below the FDA trace level.
The FDA's October 3 risk assessment of melamine and its analogues concluded that "levels of melamine and its analogues below 2.5 ppm in foods other than infant formula do not raise public health concerns."
But the agency said then that it did not have enough data to determine a safe level of melamine and its analogues in infant formula.
On Friday, an FDA official said it was still not possible to determine a safe level for infant formula containing both melamine and cyanuric acid compounds, but officials "believe that at very low levels there should not be any health concerns."
Sundlof said the trace levels of melamine or related compounds detected in the samples are 10,000-fold less than the amount associated with Chinese infant-formula contamination.
According to the World Health Organization, contaminated infant formula in China has killed four babies and caused more than 47,000 infants and children to be hospitalized with possible kidney stones.
Chinese-made infant formula is not available in the United States, because no Chinese manufacturer meets the requirements to sell infant formula in this country, according to the FDA.
It was also the combination of melamine and cyanuric acid in pet food that caused thousands of dogs and cats to be sickened last year in the United States.
The combination caused crystals to form in the animals' kidneys.
According to the FDA's updated Interim Safety Assessment, infants are more vulnerable to the combination than are older children or adults because formula could be the infants' sole source of nutrition. In addition, their kidneys may not have developed sufficiently to ward off the impact of the chemicals.

美国FDA公布婴儿奶粉中三聚氰胺容忍标准。
看来老美们也向中共看齐，成了“中共同路人”了。话说中国刚刚公布三聚氰胺限量值的时候，毒轮运们叫唤的可欢实了，什么下毒合法化了，什么G匪邪恶了。没想到美国亲爹给他们在背后捅了一刀，这大耳刮子扇的。

因為不是中國
早就想到会这样了
