Onions are likely source of E. coli outbreak linked to McDonald's
（文章来源：CNN）
Fresh slivered onions served on McDonald's
Quarter Pounders were the likely source of an E. coli
outbreak that has led to one death and illnesses in
more than a dozen states, the US Centers for Disease
Control and Prevention and US Food and Drug
Administration said Wednesday.
Additional cases associated with the outbreak have also been reported, bringing the total number of
illnesses to 90 and hospitalizations to 27. However, the CDC notes that the current risk to the public is
“very low,” as the reported illnesses happened before the affected onions were removed from food
service locations.
“It is not necessary to avoid eating onions or other foods made with onions,” the CDC said.
Last week, supplier Taylor Farms issued a recall of four onion products due to “potential E. coli
contamination.” McDonald's stores in affected areas have temporarily stopped using slivered onions, and
other fast food restaurants that received onions from this supplier – including Burger King, Taco Bell,
Pizza Hut and KFC – have proactively removed fresh onions from their menus at some locations.
It is not likely that the recalled onions went to grocery stores or directly to consumers, the CDC
said Wednesday. Diced onions used at McDonald's have also not been linked to this outbreak, according
to the FDA.
Beef patties used on Quarter Pounders were also part of the investigation, which started on October
22. But the Colorado Department of Agriculture said on Sunday that McDonald's fresh beef patties
used for the Quarter Pounder tested negative for E. coli, and the US Department of Agriculture's Food
Safety and Inspection Service said on Monday that evidence did not point to ground beef as the probable
source of the E. coli outbreak.

移除之前。
美国疾病控制与预防中心表示：“没有必要避免吃洋葱或其他用洋葱制成的食物。”

已暂时停止使用切片洋葱，其他从该供应商那里收到洋葱的快餐店，包括汉堡王、塔可钟、必胜客和肯德
