网传鱼浮灵让鱼复活吃后致癌

2015-12-15 15:05:03   中国新闻网

“太活跃的鱼别买,可能含致癌‘鱼浮灵’。”近期,很多人都在微博、微信等渠道看到了这样一则消息,称一些鱼贩往水里加入名为“鱼浮灵”的白色粉末,半死不活的鱼虾便马上变得活跃起来,而鱼浮灵会致癌。近日,国家食品药品监管局针对鱼浮灵问题发布了食品安全风险解析,称“鱼浮灵”的作用是给水产品增氧,并不像网传那样会致癌,安全风险有限。

网传

白色粉末让鱼“一秒复活”

“鱼也不能吃了?”关于“鱼浮灵”的一个实验近期在朋友圈疯传,视频里,一个盆里装着一条鱼,半死不活的,不太动弹。往盆里撒了一些白色粉末后,那条鱼马上活蹦乱跳起来。

据传,有人去菜场买鱼,结果看到惊人一幕:摊贩往大水盆内加入一种白色粉末,迅速用手搅拌,不一会儿白色粉末就溶解了,将半死不活的鱼虾倒入其中,没想到,鱼虾一会儿就活蹦乱跳开,仿佛这些鱼都是刚从河里捕回来的。鱼贩就是用这种名叫“鱼浮灵”的粉末,让濒死的鱼虾恢复活力。

这一传言还有补充版本,称不明真相的群众买了这些“起死回生”的鱼虾,那就大单了:撒过“鱼浮灵”的鱼经检验发现,鱼体内铅超标1000倍,砷超标近10万倍,可能严重危害人的肝、肾、智力等,甚至导致恶性肿瘤的发生。

市民徐女士表示,看了这个消息,她真是不敢买鱼了,“以前那些谣言还能说是口说无凭,但是这个实验太真实了。”眼看快不行的鱼,撒一点粉末就像“打鸡血”一样活力十足了,让人觉得这东西很可疑。

回应

“鱼浮灵”实际上是增氧剂

“鱼浮灵”是什么?水产品中使用“鱼浮灵”可能存在怎样的风险?记者从自治区食品药品监管局了解到,日前,国家食品药品监管总局发布了2015年第16期《食品安全风险解析》,组织有关专家解读水产品中使用的“鱼浮灵”。

据介绍,“鱼浮灵”的作用一般是应急增氧,当连续阴天或者光照强烈时,可以通过加入这类化学增氧剂来控制水体微生物的平衡,改善水质。

在鲜活水产品运输过程中,使用“鱼浮灵”能为鱼、虾、蟹等迅速提供其呼吸所必需的、充足的氧分,这不仅延长了它们的生命,还可以使因缺氧而萎靡的鱼虾活跃起来。这可解释网传实验中发生的那一幕。

调查

菜市鱼贩多用气泵增氧

鱼贩是不是真的使用“鱼浮灵”来给鱼虾“续命”?12月14日,记者走访了南宁市的飞凤市场、纬武路市场、官塘市场等多个市场,发现绝大部分摊贩都是使用气泵给鱼虾等水产品增氧。

在飞凤市场的水产行,记者看到几乎所有的摊位都有一个气泵,连着几根塑料管,分别伸进装鱼虾的几个水箱里,“咕嘟咕嘟”地冒着气泡。一名摊贩告诉记者,小小一个水箱里面装那么多鱼,肯定会缺氧的,这是在给水里打氧气。

纬武路市场的几名鱼贩都表示不知道什么是“鱼浮灵”,制氧都是靠气泵。有一名摊贩告诉记者,“鱼浮灵”是在养鱼和运输的时候用得多,“如果是卖鱼的时候要增加氧气,那肯定是用氧气泵方便了。”也有鱼贩说,卖鲜活水产品,死几条鱼肯定是难免的,有时候是鱼生病等原因,不是增点氧气就能解决问题的,所以懒得搞那么多“名堂”,“刚死的就捞出来便宜点卖,也卖得出去”。
