近日,家住南京市的一位市民因和两个朋友食用河豚引发了中毒症状,所幸被及时送到医院救治,才避免生命危险。专家提醒,眼下正值春季,要警惕以下4种食物引发中毒。%D%A  一是去年冬季腌制的酸菜、咸菜。随着春季气温的升高,酸菜和咸菜中的亚硝酸盐含量会增加,一次性食用过多颜色过深、已变黏的酸菜或咸菜,容易引起亚硝酸盐中毒。%D%A  二是冷冻海产品。春季是海产品的产出淡季,如冷冻海产品存放时间过长或存放不当,就容易腐败变质,所含的蛋白质(蛋白质食品)就分解,并且产生胺类、可溶性毒蛋白、吲哚、恶臭素等有毒害的物质。而且经加热煮、熬并不能彻底破坏这些有毒物质的毒性。%D%A  三是河豚。近期是河豚产卵季节,也是食用河豚中毒的高危险期。河豚的毒素一般加热烧煮不能解毒,严重的在中毒后两三个小时内就会导致死亡。%D%A  四是有毒山野菜。随着天气转暖,各种山野菜陆续生长。如果采食有毒植物或者加工不当的山野菜,容易引起中毒,严重的将危及生命。%D%A  东南大学附属中大医院 程守勤%D%A  发芽土豆也有毒%D%A  春季是土豆所致食物中毒的多发季节,如果食用发芽或储存不当出现黑斑的土豆,就可能引起中毒。土豆中引起中毒的物质叫“龙葵素”,正常土豆中的龙葵素含量较少,春季土豆发芽后,其皮肉会变绿,龙葵素含量随之升高。龙葵素中毒后,潜伏期为数十分钟至数小时,患者出现舌、咽麻痒、胃部灼痛及胃肠炎症状;瞳孔散大,耳鸣等症状;重病者抽搐,意识丧失甚至死亡。如果土豆已发芽或变色,食用前一定要将发芽、变色的部分挖掉,然后把切好的土豆放到水里浸泡一小时以上,对于发芽、变色面积过大的土豆千万不要食用。林风%D%A
