"沃尔玛惊现'核能虾'！"美国FDA近日发出警告，要求13个州的消费者赶紧扔掉沃尔玛旗下Great Value品牌的冷冻虾产品，原因竟是这批来自印尼的海鲜可能被放射性物质铯-137污染。最魔幻的是，其中一批面包虾的检测样本居然真的呈阳性，幸好还没流入市场。沃尔玛赶紧表态"顾客安全是首要任务"，一边下架问题产品，一边承诺全额退款。不过专家说了，这批"辐射虾"的辐射量虽然不会立即危害健康，但长期食用可能增加患癌风险。要知道铯-137可是切尔诺贝利和福岛核事故的主要辐射源之一，现在居然出现在了超市货架上！网友调侃："这虾是不是游经福岛海域时顺便充了个电？"目前印尼供应商的多批集装箱已被美国拒之门外，看来这波"海鲜危机"还得持续一阵子~
