小龙虾（学名：Procambarus clarkii）：是甲壳纲、十足目、螯虾科水生动物。小龙虾通常携带肺吸虫，也称克氏原螯虾、红螯虾和淡水小龙虾。形似虾而甲壳坚硬。成体长约5.6-11.9厘米，暗红色，甲壳部分近黑色，腹部背面有一楔形条纹。幼虾体为均匀的灰色，有时具黑色波纹。螯狭长。甲壳中部不被网眼状空隙分隔，甲壳上明显具颗粒。额剑具侧棘或额剑端部具刻痕。
是淡水经济虾类，因肉味鲜美广受人们欢迎。因其杂食性、生长速度快、适应能力强而在当地生态环境中形成绝对的竞争优势。
其摄食范围包括水草、藻类、水生昆虫、动物尸体等，食物匮乏时亦自相残杀。小龙虾近年来在中国已经成为重要经济养殖品种。在商业养殖过程中应严防逃逸，尤其是严防逃入人迹罕至的原生态水体。其对当地物种生态竞争优势而导致破坏性危害。
那小龙虾食品出口美国需要办理FDA认证吗？下面我们先了解下什么是FDA。
美国食品和药物管理局(Food and Drug Administration)简称FDA，FDA是美国政府在健康与人类服务部(DHHS) 和公共卫生部(PHS) 中设立的执行机构之一。作为一家科学管理机构，FDA的职责是确保美国本国生产或进口的食品、化妆品、药物、生物制剂、医疗设备和放射产品的安全。它是最早以保护消费者为主要职能的联邦机构之一。在中国人们喜欢叫FDA认证，其实称呼FDA认证更贴切些。FDA认证通常分为如下几类：
1、食品FDA认证（普通食品、低酸罐头食品）
2、药品FDA认证
3、医疗器械FDA认证
4、辐射发光类产品FDA认证
5、生物制剂FDA认证
6、动物兽医FDA认证
7、化妆品（非强制）FDA认证
8、烟草制品FDA认证
