FDA 调查生牛奶酪大肠杆菌疫情：Sierra Nevada Graziers 四款生奶奶酪在全美召回
华盛顿——美国食品药品监管局（FDA）正在调查一起与生牛奶酪有关的产志贺毒素大肠杆菌 O26:H11 疫情。FDA 表示，被召回的 Sierra Nevada Graziers 草饲生奶奶酪包括中度切达、浓味切达、哈雷派尼奥杰克与蒙特雷杰克四款，零售装为8盎司或16盎司包装，餐饮与批发渠道为5磅装，在全美零售店与网上销售，消费者不要食用、出售或供应。
据 FDA 介绍，大肠杆菌感染症状通常在食用受污染食品后数天至9天内出现，包括严重胃痉挛、腹泻、发烧、恶心或呕吐；部分感染可导致溶血性尿毒症综合征等危及生命的肾衰竭并发症，幼儿与老年人风险更高。由于该产品保质期较长，FDA 建议消费者检查冰箱与冷冻室，无法确认是否属于召回批次的奶酪应直接丢弃；购买者可退回购买处退款，并对奶酪接触过的表面与容器进行清洁消毒，以防交叉污染。（GSM 据 FDA 官网疫情调查页报道）
FDA Probes E. coli O26:H11 Outbreak Tied to Sierra Nevada Graziers Raw Milk Cheeses
WASHINGTON — The U.S. Food and Drug Administration (FDA) is investigating an outbreak of Shiga toxin-producing E. coli O26:H11 infections linked to raw milk cheese. The recalled Sierra Nevada Graziers grass-fed raw milk cheeses — medium cheddar, sharp cheddar, jalapeno jack, and Monterey jack — were sold at retail nationwide and online in 8-ounce and 16-ounce packages, and to food service customers and wholesalers in 5-pound loaves. The FDA says consumers should not eat, sell, or serve the recalled cheeses.
Symptoms of E. coli infection begin anywhere from a few days after consuming contaminated food to nine days later, and include severe stomach cramps, diarrhea, fever, nausea, and vomiting; some infections can lead to hemolytic uremic syndrome, a type of kidney failure. Because the cheese has a long shelf life, the FDA advises checking refrigerators and freezers, throwing away any cheese that cannot be ruled out of the recall, returning recalled product for a refund, and carefully cleaning and sanitizing surfaces and containers the cheese touched.
