前日,省疾控中心官方微信“福建疾控”发布提醒,这段时间的田螺特别肥美,不过在吃之前要确定,你吃的是田螺,而不是“暗藏杀机”的福寿螺。

随着气温上升,福寿螺繁殖季节来临。那么,福寿螺到底能不能吃?省疾控中心寄生虫病防治研究室专家陈云虹介绍,福寿螺是不能食用的。

福寿螺是一种人畜共患寄生虫病的中间宿主,每只福寿螺内可含广州管圆线幼虫3000条~6000条。如果生吃螺肉,或食用未煮熟的螺肉,极易引起食源性广州管圆线虫病。

感染此病后,幼虫会侵入人脑,损害中枢神经系统,引起嗜酸细胞增多性脑膜炎,做血液检查可发现患者嗜酸性粒细胞水平急剧升高。

患者进食螺肉后2天~5天内发病,临床表现为头痛,伴有恶心呕吐、颈项强直、活动受限、抽搐等症状,重者可导致瘫痪,甚至死亡。

福寿螺外观与田螺极其相似,那么,在野外如何分辨福寿螺还是田螺?

“福寿螺喜欢在离水面15厘米~40厘米的池壁、木桩、水生植物的茎叶上产卵。‘粉红色的卵块’是辨认福寿螺最容易的特征之一。田螺的卵为透明色。”陈云虹介绍。此外,福寿螺个大,要比田螺大好几倍;福寿螺的外壳呈淡橄榄绿色或黄褐色,田螺的外壳颜色则为青褐色。

福建疾控:福寿螺“暗藏杀机”,不能食用
