生牛奶奶酪大肠杆菌暴发结束：10个州18人感染、9人住院、3人出现溶血性尿毒综合征、无人死亡
美国食品药品管理局11月13日更新暴发调查页称，该局与疾控中心及州、地方伙伴调查的一起多州大肠杆菌 O26:H11 暴发已经结束，疾控中心宣布暴发结束，食品药品管理局的暴发调查亦已关闭。
这起暴发与 Sierra Nevada 公司的 Graziers 草饲生牛奶奶酪相关。据疾控中心与各州收集的信息，共有10个州报告18人感染暴发菌株，涉及加利福尼亚州、科罗拉多州、佐治亚州、肯塔基州、密歇根州、内华达州、新墨西哥州、俄勒冈州、田纳西州与犹他州。发病日期自2026年7月7日至9月20日，其中9人住院、3人出现溶血性尿毒综合征，无人死亡。
在接受访谈的15名患者中，15人全部报告发病前吃过 Sierra Nevada Graziers 草饲生牛奶奶酪。调查期间，加利福尼亚州公共卫生部门从患者家中采集的已开封生牛奶中度切达奶酪样本检出大肠杆菌，全基因组测序显示与暴发菌株匹配；密歇根州有关部门采集的同类产品样本则检出另一株大肠杆菌。
被召回产品为 Sierra Nevada Graziers 草饲生牛奶奶酪，包括中度切达、辛辣切达、辣椒杰克与蒙特雷杰克，零售装为8盎司或16盎司，另有供餐饮与批发客户的5磅装；产品销往全国零售与线上渠道，并曾分销至韩国。食品药品管理局9月24日联系该公司并建议召回，公司同日同意并启动全部 Graziers 生牛奶奶酪召回。
食品药品管理局提醒，被召回产品保质期较长、可能仍存放在消费者家中，应检查后丢弃或退回购买处退款；无法确认无包装冷藏或冷冻奶酪是否属召回范围的，也应丢弃。购买或接收过被召回奶酪的消费者、餐厅、零售商与餐饮客户应仔细清洁消毒接触过的表面与容器；吃过被召回奶酪并出现大肠杆菌感染症状者，应立即联系医疗提供者。

E. coli Outbreak Linked to Raw Milk Cheese Ends: 18 Illnesses in 10 States, 9 Hospitalizations, 3 Cases of Hemolytic Uremic Syndrome, No Deaths
The Food and Drug Administration updated its outbreak investigation page on November 13, 2026, stating that the multistate outbreak of E. coli O26:H11 infections linked to Sierra Nevada Graziers grass-fed raw milk cheese has ended. The CDC is declaring the outbreak over, and the FDA's outbreak investigation has closed.
A total of 18 people infected with the outbreak strain were reported from 10 states: California, Colorado, Georgia, Kentucky, Michigan, Nevada, New Mexico, Oregon, Tennessee and Utah. Illnesses started on dates ranging from July 7 to September 20, 2026. There were 9 hospitalizations, 3 cases of hemolytic uremic syndrome and no deaths.
Of the 15 ill people interviewed by state and public health officials, all 15 reported consuming Sierra Nevada Graziers grass-fed raw milk cheese before getting sick. An opened sample of the raw medium cheddar collected from a sick person's home by the California Department of Public Health tested positive for E. coli and matched the outbreak strain by whole genome sequencing; a sample collected in Michigan tested positive for a different strain of E. coli.
The recalled products are Sierra Nevada Graziers grass-fed raw milk cheeses, including medium cheddar, sharp cheddar, jalapeno jack and Monterey jack, sold at retail in 8-ounce or 16-ounce packages and to food service customers and wholesalers in 5-pound loaves, distributed nationwide and to the Republic of Korea. The FDA contacted the firm on September 24, 2026, and the company agreed the same day to recall all Graziers raw milk cheeses.
The FDA notes that the recalled product has a long shelf life and reminds consumers to check their homes for it and discard it or return it to the place of purchase for a refund. Consumers who refrigerated or froze cheese without the original packaging and cannot tell if it is part of the recall should throw it away, and surfaces and containers the cheese touched should be carefully cleaned and sanitized.
