华盛顿 — 美国食品药品管理局 11 月 9 日更新疫情调查页称，该局与疾病控制与预防中心及州和地方伙伴调查的一起多州产志贺毒素大肠杆菌与沙门氏菌感染疫情已经结案，疾控中心已宣布疫情结束，食品药品管理局的疫情调查亦已完成。
截至 11 月 9 日，共有 16 个州报告 77 人感染，其中感染大肠杆菌的 64 人、感染沙门氏菌的 10 人、同时感染两者的 3 人。发病日期从 2026 年 5 月 31 日至 10 月 19 日，共 6 人住院，无死亡报告。在受访的 52 人中，41 人即 79% 报告食用过芽苗，其中 36 人明确食用了苜蓿芽苗。
调查把疫情与被召回的苜蓿种子批次 SAL2-24JB 联系起来，该批次有效期至 2029 年 12 月 31 日。食品药品管理局表示，由该批次种子种出的被召回芽苗已过最佳食用期，应已不在商店与餐馆出售，但种子批次本身仍可能留在种植者库存中。
食品药品管理局的建议包括：不要使用或出售被召回的发芽种子，芽苗种植者应清查库存并丢弃该批次剩余种子，消费者应检查家中是否有被召回产品并丢弃，相关经营者应按该局的安全处理与清洁指引清洁消毒接触过的表面与容器。
Berlin Seeds 品牌的苜蓿发芽种子曾于 2026 年 2 月 13 日至 8 月 23 日在俄亥俄州米勒斯堡的该公司零售店及其官网出售，销售范围覆盖包括加利福尼亚州与德克萨斯州在内的多州。被召回种子批次也曾分发至波多黎各以及加拿大、墨西哥等地。
FDA and CDC Close the Multistate Alfalfa Sprouts Outbreak on November 9: 77 Illnesses in 16 States, 6 Hospitalizations and No Deaths, With Seed Lot SAL2-24JB Expiring December 31, 2029
Washington — In a November 9 update to its outbreak investigation page, the Food and Drug Administration said the multistate outbreak of Shiga toxin producing E. coli and Salmonella infections it investigated with the Centers for Disease Control and Prevention and state and local partners is over, with the CDC having declared the outbreak ended and the FDA outbreak investigation complete.
As of November 9, a total of 77 people from 16 states were reported infected, including 64 infected with E. coli, 10 infected with Salmonella, and 3 infected with both. Illnesses started from May 31, 2026, to October 19, 2026. There were 6 hospitalizations and no deaths. Of 52 people interviewed, 41, or 79 percent, reported eating sprouts, and 36 specified eating alfalfa sprouts.
The investigation linked the outbreak to recalled alfalfa seed lot SAL2-24JB, which has an expiration date of December 31, 2029. The FDA said recalled sprouts grown from that seed lot are past their best by dates and should no longer be available in stores or restaurants, while the seed lot itself may still remain in grower inventory.
FDA recommendations include not using or selling recalled sprouting seeds, sprout growers checking inventory and discarding any remaining seed from the lot, consumers checking their homes for recalled products and throwing them away, and businesses cleaning and sanitizing surfaces and containers that touched the products under FDA safe handling and cleaning advice.
Berlin Seeds branded alfalfa sprouting seed was sold at the company retail store in Millersburg, Ohio, and through its website from February 13, 2026, to August 23, 2026, to customers in many states including California and Texas. The recalled seed lot was also distributed to Puerto Rico and internationally to Canada, Mexico and other places.
