“阳澄湖大闸蟹”开售? 官方:23日前均为假冒原标题:秋风起吃蟹好时节 别被这些螃蟹的谣言给坑了“秋风起,蟹脚痒”,农历九月前后,正是吃蟹的好时节,可是诸如“吃蟹黄可能致癌”、“螃蟹注水增重”、“螃蟹打激素”等传闻却不绝于耳,惹得众多网友对“安全吃蟹”产生疑问。这些传言到底是真是假呢?一起来看看吧!1、吃蟹黄可能致癌?水产专家:人工养殖安全可控【传闻】连日来,一条有关“蟹黄不能吃”的传闻,在微博、微信等平台流传:美国纽约卫生局叫停华人吃蟹,称蟹黄、蟹膏处化学物质集中、重金属超标,会严重影响人的健康,甚至可能致癌。【真相】成都市农林科学院水产所研究员曹英伟在接受《华西都市报》采访时认为,网上的说法有些以偏概全,螃蟹是否重金属超标,是否对人体有害,至少要从三方面考虑。首先是生长水域会影响螃蟹。如果在良好水域生长,螃蟹的重金属含量微乎其微,传言中说出问题的螃蟹,应仅仅是指纽约的某个被污染水域。目前,国内大部分螃蟹是人工养殖的,具有可控性,若水质、用药等方面检测合格,养出的蟹可放心食用。其次,他从生物角度分析,螃蟹最易受污染的部位,其实并不是蟹黄,而是蟹腮、蟹肺、蟹肝等不食用的部位。最后,摄入不大一般来说不会有问题。2、“阳澄湖大闸蟹”开售? 官方:23日前均为假冒【传闻】近日,有北京市民反映,一些水产市场、淘宝网店在九月初就开始售卖阳澄湖大闸蟹,有的还带着防伪扣。那么,这些大闸蟹是真的吗?【真相】苏州市阳澄湖大闸蟹行业协会日前发布消息,今年大闸蟹开捕时间为9月23日。同时,该协会工作人员表示,阳澄湖大闸蟹捕捞都有统一管理,在开捕前还未上市,市面上售卖的任何称‘阳澄湖大闸蟹’的螃蟹均为假冒。同时,真正阳澄湖大闸蟹的防伪标志只有在开湖捕捞后才有。3、商家给螃蟹打针增重?专家称会迅速死亡【传闻】近日,一段“商家给青蟹打针注水”的视频在微信朋友圈流传。该视频显示,一位大妈手持注射器给一筐蟹逐只注射不明液体。有网民称,“这是不法商贩往螃蟹体内注水增重”,还有人称“这是注射假蟹黄毒害老百姓”。【真相】所谓的“注水螃蟹”其实是一则流传多年的谣言,早已被多地工商部门鉴定为虚假消息。国内多位专家表示,往螃蟹体内注入液体后,环境渗透压会产生剧变,脏器要么失水要么吸水,都会导致螃蟹的迅速死亡。同时,有实验表明,注水时螃蟹腹部会漏水,不到10分钟螃蟹就死了。而死蟹很少有人买,不论从商业角度还是技术层面,这种行为都是得不偿失的。4、大闸蟹靠激素养肥?专家称抑制发育【传闻】有网民称,“大闸蟹是注射激素长大的,小孩吃了会导致提前发育”;还有人称,“现在的大闸蟹根本不能吃的,一般至少两年才能长到二两,可现在都是一年就上市,靠的是激素,人吃怎么会健康呢?”这些说法引发了部分网友的关注。【真相】从科学角度来看,雌激素喂养大闸蟹根本不可能也不现实。激素对大闸蟹起不了任何作用,螃蟹属于低等无脊椎动物。从生物学角度说,秋分前后螃蟹蜕壳为绿蟹,性腺开始迅速发育;而人们吃蟹喜爱的蟹黄和蟹膏,恰是螃蟹的性腺。给螃蟹吃高等脊椎动物激素之类的药物正好抑制了性腺的发育,反而会导致大闸蟹的蟹黄和蟹膏变少。5、西红柿加螃蟹等同吃砒霜?现实中不可能【传闻】网上一则“螃蟹和西红柿同食如吃砒霜”的消息,引起众多网友关注。有微博称,螃蟹中的五价砷和西红柿里的维生素C会氧化产生砒霜。【真相】专家认为,中毒的可能性在现有生态环境及日常饮食的条件下不太可能发生。中国农业大学食品科学与营养工程学院副教授朱毅在微博中表示,“在实验室里,维生素C有可能使五价砷转变为毒性很强的三价砷,但在饮食上要达到这个效果很不容易。首先,要吃几公斤被严重砷污染的螃蟹,之后维生素C为一次性服用500毫克以上,也就是一次性摄入5斤以上西红柿才有中毒可能性,显然这种可能性在目前生态环境和日常饮食中是不太可能的。”6、避孕药喂螃蟹?专家称得不偿失【传闻】有传言称:“螃蟹是避孕药喂大的,多吃螃蟹儿童会性早熟。”还有传言说,“现在有些螃蟹吃起来肉质酥松,味道有点苦,可能是喂了避孕药。”【真相】对于这些传言,朱毅认为,流言未分公母蟹,就是一大漏洞,雌雄同湖,避孕药剂岂能自辨其主,所以投放难度系数极大;再则,当家长们极为忧虑“性激素从口入”导致儿童性早熟的时候,养蟹人也在发愁螃蟹的性早熟呢,螃蟹性早熟和激素自也是息息相关,对于水体中可能的环境内分泌干扰物养殖户都避之唯恐不及,岂敢擅自胡乱添加避孕药。最受欢迎的蟹黄蟹膏实质就是螃蟹的性腺,避孕药自是会影响其发育,目前通过外源激素获得螃蟹养殖的高比例单性技术还未出炉,所以盲目添加只会得不偿失。由此可知,螃蟹断是不可能吃着避孕药长大的。7、孕妇不能吃螃蟹?专家称“滑胎食物”太夸张【传闻】网传“孕妇吃螃蟹会流产”,记者上网检索容易导致流产的食物中,螃蟹“榜上有名”,那到底孕妇能不能吃呢?吃了就会导致流产吗?【真相】据《生命时报》报道,哈尔滨医科大学附属第四医院妇产科主任蔡雁教授指出,临床上从未发现流产与吃任何正常食物有关。网上流传的孕妇吃了某种食物导致流产,可能与个人体质有关,比如对异种蛋白过敏的女性,怀孕后如果大量吃高蛋白食物,如螃蟹、大虾、鱼类等,这些食物中的异种蛋白直接或间接地激活免疫细胞,引起化学介质的释放,继而引起全身过敏症状,其中包括腹泻,而腹泻会使肠蠕动加快,甚至出现肠痉挛,进而刺激子宫收缩导致流产。同时专家提醒,对于本身体质就偏寒的孕妇来说,吃寒凉的食物一定要减量,比如每次只吃一只螃蟹。吃蟹小贴士1、不吃死螃蟹。因为螃蟹濒临死亡时体内会分泌一种有毒物质组胺,且会随着死亡时间延长而累积。当然死后的蟹肉也会迅速腐败变质,滋生其它细菌生长。2、吃螃蟹忌生食需煮熟。虽然螃蟹有醉蟹的吃法,但是由于水质问题,螃蟹体内往往滋生有着大量的细菌,所以吃螃蟹一定熟吃,不要贪食美味而生吃。煮螃蟹也一定要煮熟蒸透、高温杀菌,使蟹壳发红后,食之。3、隔夜的剩蟹不宜吃。螃蟹为含组胺酸较多的食物,隔夜食用可能导致组胺中毒。4、吃螃蟹一次应控制在2只内。一般来说,螃蟹一次吃1-2只就够了,从营养学的角度,它含有高胆固醇和蛋白质,不容易消化。5、忌茶水、香瓜、梨子、花生、泥鳅等食物同食。蟹为寒性,同食寒重则损伤脾胃,导致腹泻。(人民网)视频推荐: 阳澄湖大闸蟹还未开捕 市场上已经有售?相关的主题文章:
