UPDATE: Nov. 17, 2021:FDA有increased the number of illnessesconnected to this outbreak to 892 cases in 38 states and Puerto Rico. Additionally, a少数其他公司— including Pier-C Produce,Potandon生产，HelloFresh和EveryPlate— have recalled products that may have contained these contaminated onions.
潜水简报:
- 在沙门氏菌爆发后，在37个州的652人中生病了652人，住院129，从潜在源生产和基尔家庭农场的进口洋葱已被自愿回忆起根据FDA的说法。洋葱生长在奇瓦瓦岛墨西哥州，进入美国7月1日至8月31日之间。
- So far, all of the illnesses have been traced to restaurants serving raw onions, but FDA is asking consumers who may have purchased onions of any type from these distributors at retail to throw them away as well. FDA is目前调查来源of the contamination.
- This is the second large salmonella outbreak caused by onions in two years. In 2020, more than 1,600 people in the U.S. and Canada吃了污染的红洋葱后病了。
潜入洞察力：
While this year's salmonella outbreak tied to onions isn't yet as massive as the one inAugust and September 2020, it bears some resemblance in its scope and potential cause.
去年的爆发与加利福尼亚州汤姆森国际的Bakersfield生产的红洋葱有关。FDA做了a comprehensive study试图找到根本原因，但发现没有对来源的确凿证据。然而，调查人员认为它可能在灌溉用水中污染洋葱种植的领域，因为在那里发现了许多不同的沙门氏菌。他们从该地区和洋葱农场附近的各个地点采用样品。报告称，Salmonella以10种不同地点的样品存在。
As this outbreak is still in its beginning stages, not much is known about how widespread the contamination was or the growing practices of the two farms. However, both are located in the same Mexican state, and it is conceivable that they are served by common water sources.
In the past decade, the FDA has renewed its focus on making the U.S. food supply safe by preventive measures outlined in theFood Safety Modernization Act奥巴马总统于2011年签署了法律.FSMA为制造商提出了一套新的安全措施，也授权检验，对农场的有利危害和水测试培训，这在之前没有任何一致性。它需要一些时间来获得Produce Safety rulein full effect — it became required for all farms last January — and rulemaking about water quality testing is still ongoing.
但是，这没有任何可能适用于这里。洋葱是从墨西哥进口的。虽然FSMA需要粮食进口商遵守与美国的同行相同类型的规则，但规定这些检查的规则是不一样的。进口商由FSMA的管辖外国供应商验证计划。Companies in this program need to conduct hazard analyses, just like U.S. entities, and they are subject to FDA inspections.
But given the difficulty of implementing water testing regulations for domestic farmers and thelong pause of FDA inspectionsof foreign facilities due to the pandemic, it's unclear how much scrutiny may be applied to farms in Mexico right now.According to FDA records，Keeler家庭农场目前是FSMA外国供应商验证计划的一部分 - 这意味着它沿FDA规则和测试进行了危险分析，以确保食品是安全的 - 但潜在生产不是。
这种爆发有两种可能的长期成果。外国农场的检查及其水质可能会成为FDA的优先事项，该部门可能在确保其安全方面采取更积极的作用。一些作物，如绿叶蔬菜，容易吸收和传播污染。洋葱被认为不易受到污染的影响，但最近的事件表明并非如此。可能存在以前未知的东西，使洋葱特别容易受到污染 - 或洋葱农业的常见做法，导致这两个爆发并需要更多的监管。
爆发有already spurred a lawsuit。该法律诉讼将于该周四提交了ProSource生产，成功的食品管理组及其Torchy的Tacos Restaurant Chain代表一名未成年人在德克萨斯州San Antonio的火炬位置吃洋葱后，据称开发了沙门氏菌感染。
