一款奶酪也不能留：Clover Hill全部奶酪召回含切达，疫情终查15人患病1人死亡
查冰箱时认奶酪先认生产商许可号，这是马里兰州 Clover Hill Dairy 这场召回留下的最实用一条。美国食品药品监督管理局（FDA）与疾病控制与预防中心（CDC）已在2026年8月26日结案这起李斯特菌疫情调查，终查数字是四州共15人患病、14人住院、1人死亡（马里兰州），发病日期从2023年3月6日一路跨到2026年7月8日。市面上已不应再有涉事产品在售，但两家机构结案时仍提醒消费者检查自家冰箱和冷冻柜。
召回的范围值得说清。这家位于 Mechanicsville 的奶厂2026年6月3日先自愿召回自家的 requesón 和软质 ricotta 奶酪，6月18日把召回扩大到工厂生产的全部奶酪，包括切达、Monterey Jack、Colby、胡椒杰克、烟熏切达和奶酪粒等硬质品种。马里兰州卫生部门此前已吊销该厂的经营许可。
麻烦在于换牌销售。涉事奶酪有一部分被改贴其他品牌出售，包括 KESSO、Quesos La Ricura、Izalco、De Mi Pueblo 和 Rio Lindo，包装正面的牌子靠不住，不变的只有生产商许可号 24-128。家里若还有来路不明的软奶酪或切达，先翻标签找这个号，对上就不要吃。
实验室证据是这起调查的定案依据：六份 requesón 产品样本和工厂环境样本检出的李斯特菌，经全基因组测序与病例菌株对上。李斯特菌对孕妇、老年人和免疫力弱的人尤其危险，家里有这类成员的，结案之后也值得把冰箱再翻一遍。（来源：美国食品药品监督管理局）
No Cheese From This Dairy Was Left Out: Clover Hill's Recall Covered Every Cheese Including Cheddar, and the Outbreak Closed at 15 Illnesses and One Death
The most useful habit from the Clover Hill Dairy recall is to identify cheese by the plant number on the label. The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention closed their Listeria investigation on August 26, 2026, with a final count of 15 people infected across four states, 14 hospitalized and one death in Maryland, with illness onsets ranging from March 6, 2023 to July 8, 2026. The products should no longer be on sale, but both agencies' closing guidance still asks consumers to check their refrigerators and freezers.
The scope of the recall matters. The Mechanicsville, Maryland dairy first recalled its requesón and soft ricotta cheeses voluntarily on June 3, 2026, then expanded the recall on June 18 to every cheese made at the facility, including hard cheeses such as cheddar, Monterey Jack, Colby, pepper jack, smoked cheddar and cheese curds. The Maryland Department of Health had already suspended the dairy's operating license.
Relabeling is what makes the check harder. Some of the cheese was sold under other brand names, including KESSO, Quesos La Ricura, Izalco, De Mi Pueblo and Rio Lindo, so the name on the front of the package is not the reliable marker. The manufacturer permit number 24-128 is. Any soft cheese or cheddar at home carrying that number should not be eaten.
The laboratory evidence closed the case: Listeria found in six product samples of requesón and in environmental samples from the facility matched the outbreak strain through whole genome sequencing. Listeria is especially dangerous for pregnant women, older adults and people with weakened immune systems, which is why the refrigerator check is still worth doing after the investigation has closed.
