E. coli Outbreak Linked to McDonald's Quarter Pounders Sickens 49

An E. coli outbreak linked to McDonald’s Quarter Pounders has sickened 49 people across 10 US states, resulting in one death.  In response, the company has halted slivered onion distribution and removed the Quarter Pounder from affected menus. This incident is occurring during a period of declining sales, which led to a 9% drop in the company's shares, highlighting significant food safety concerns and potential reputational damage.

The Centers for Disease Control and Prevention (CDC), along with the FDA and USDA, is investigating an outbreak of E. coli O157. While a specific ingredient has not yet been pinpointed as the cause, investigators are concentrating on onions and beef. A preliminary FDA investigation suggests that slivered onions served on the burgers are a likely source of contamination, while the United States Department of Agriculture (USDA)  is looking into the hamburger patties, reports AP News. 

Infections were reported between September 27 and October 11 in Colorado, Iowa, Kansas, Missouri, Montana, Nebraska, Oregon, Utah, Wisconsin, and Wyoming. Among them, Colorado reported the highest number of cases at 27, followed by Nebraska with nine, writes AP News. 

In response to the outbreak, the company has ceased distribution of slivered onions and temporarily removed the Quarter Pounder from menus in the affected states, reveals the CDC. 

“We take food safety extremely seriously and it’s the right thing to do,” McDonald’s said in a statement.

Symptoms of this infection often include severe stomach cramps, bloody diarrhea, and vomiting. While most people recover within 5 to 7 days, some cases can lead to serious kidney complications.
