Because the affair is actually very serious, we might as well take in to analyze once;Need not to doubt first, health department and three deer companies all have already publicly admitted at least 700 ton baby's kid's milk powders be subjected to three chlorine cyanotype An pollution, have already found out an in a short time number as well, the province appears numerous babies and kids in the meantime, the Bi urine system stone calculus really is because ate a milk powder in of three chlorine cyanotype An result in, so we will ask, three deer companies admit of just have 700 ton milk powders to be subjected to three chlorine cyanotype An pollution, talk the idea of bottom may be an emergence surprised in the production of circumstance, be also say that not and intentionally add of three chlorine cyanotypes the An be this kind of chemistry product, let the public produce a kind of imagination, perhaps just individual case, the Zhao returns to product behind again check pure pollution the reason can resolve a problem, after all this be a Zhao the race brand of, it is all to be loudly appealing and protecting race brand now?

由于事情实际上很严重，我们不妨加以分析一下；首先，毋庸置疑，卫生部和三鹿公司都已经公开承认至少有700吨婴幼儿奶粉受到三氯氰胺污染，也已经查明短时间内数省同时有众多婴幼儿出现泌尿系统结石确实是因为食用了奶粉中的三氯氰胺所造成，那么我们就要问了，三鹿公司承认的只是有700吨奶粉受到了三氯氰胺污染，言下之意可能是生产中出现意外的情况，也就是说并非故意添加的三氯氰胺这种化学制剂，让公众产生一种想象，也许只是个案，召回产品后再查清污染原因就可以解决问题了，毕竟这是一个著名的民族品牌，现在不是都在大声呼吁要保护民族品牌吗？
