FDA确认种子批次W4105为西兰花芽沙门氏菌疫情源头：六州32人感染，家庭催芽种子再现召回
华盛顿10月7日——据食品安全法律媒体LexBlog对FDA与CDC通报的汇总，监管机构已确认种子批次W4105与Evergreen西兰花芽沙门氏菌疫情的菌株匹配：截至10月7日，爱达荷、明尼苏达、蒙大拿、俄勒冈、犹他与华盛顿六州共32人感染，3人住院，无死亡报告；最近一名患者的发病日期为9月3日。疫情状态仍标注为进行中。
五天之内，同一批次已触发第二次面向家庭催芽种子的召回，涉及Eden Brothers公司。FDA表示，被召回的芽菜虽已过保质期，但被召回的种子可能仍存放在家庭中；家庭催芽者应核对包装上的批次号。FDA明确提示：不要种植、催芽、食用被召回种子，也不要用其培育微型蔬菜；清洗无法去除种子内部的沙门氏菌，催芽环境反而会让细菌繁殖。处理方式是密封后丢弃并申请退款。
沙门氏菌是美国最常见的食源性病原体之一，也是食源性住院与死亡的首要原因。症状通常在进食后6小时至6天出现，包括腹泻、发热与胃痉挛，持续4至7天；部分患者其后可能出现反应性关节炎或肠易激综合征。
对普通消费者的直接落点有三条：第一，购买催芽种子时认准包装上的批次号并拍照留存；第二，催芽成品如无把握，宁可丢弃不要食用，尤其是为幼儿与老人准备的餐食；第三，出现持续腹泻、发热超过两天或脱水迹象时及时就医，并告知医生近期芽菜进食史，帮助实验室做针对性检测。

FDA Confirms Seed Lot W4105 as Source of Broccoli Sprout Salmonella Outbreak: 32 Sick in Six States
WASHINGTON, Oct. 7 — The FDA has matched seed lot W4105 to the strain behind the Evergreen broccoli sprout Salmonella outbreak, according to a LexBlog summary of FDA and CDC postings. As of Oct. 7 the agencies listed the outbreak as ongoing: 32 sick in Idaho, Minnesota, Montana, Oregon, Utah and Washington, three hospitalized and no deaths, with the last reported illness starting Sept. 3. The recalled sprouts are past their use-by dates, but recalled seed may still be in homes; no illnesses have been reported from either seed recall.
Within five days, the same lot triggered a second home-sprouting seed recall, by Eden Brothers. The FDA says consumers should not plant, sprout, eat or grow microgreens from recalled seed. Washing does not remove Salmonella from inside a seed coat, and sprouting conditions let the bacteria multiply. The agency advises throwing the seed away sealed in the trash and requesting a refund, and urges anyone who sprouts at home to check the lot number on the packet.
Salmonella is among the most common foodborne infections in the United States and a leading cause of foodborne hospitalizations and deaths. Symptoms usually appear six hours to six days after exposure and include diarrhea, fever and stomach cramps lasting four to seven days; some patients later develop reactive arthritis or irritable bowel syndrome.
For consumers, the practical points are three: photograph and keep the lot number on any sprouting-seed packet you buy; when in doubt about finished sprouts, discard rather than eat them, especially in meals for children and older adults; and seek care promptly for diarrhea lasting more than two days, persistent fever or signs of dehydration, telling the doctor about recent sprout consumption so the laboratory can run targeted tests.
