Investigation of the Oct. 27-Oct. 11 Flares of McDonald’s Delayed by a Single Supplier of Onions

The majority of those interviewed said they had eaten at McDonald’s before falling ill, according to the CDC. The U.S. Agriculture Department, the Food and Drug Administration and state health officials are also investigating.

One child in Colorado has been hospitalized with irreversible damage to their nephrons, the Centers for disease Control and Prevention reported.

The U.S. Centers for Disease Control and Prevention reported the outbreak late Tuesday. It said infections were reported between Sept. 27 and Oct. 11 in Colorado, Iowa, Kansas, Missouri, Montana, Nebraska, Oregon, Utah, Wisconsin and Wyoming. One person in Colorado died, and 10 people were hospitalized.

The preliminary investigation suggests that fresh onions that are served raw may be the source of the problem. The company said it is looking for a new regional supplier for onions and that Quarter Pounders have been removed from menu in one fifth of its US restaurants.

In a statement, McDonald’s officials said that initial findings suggest that some illnesses are linked to onions sourced from a single supplier. In some states, the company halted distribution of the onion and Quarter Pounder, while also temporarily removing them from menu in other states.

The E. coli O157:H7 outbreak at McDonald’s has not stopped in the Second Quarter, but its Public Health Officials are Rejoinded

Animals are harbored in E. coli in the environment. Infections can cause severe illness, including fever, stomach cramps and bloody diarrhea. People who develop symptoms of E. coli poisoning should seek health care immediately and tell the provider what they ate.

The news is bad for the McDonald’s chain. In the second quarter, its global same-store sales fell for the first time in nearly four years. A $5 meal deal was introduced at U.S. restaurants in late June and has been extended through December. The deal doesn’t include the Quarter Pounder.

The type of bacteria implicated in this outbreak, E. coli O157:H7, causes about 74,000 infections in the U.S. each year, leading to more than 2,000 hospitalizations and 61 deaths. Infections are especially dangerous for children younger than 5 and can cause acute kidney failure.

McDonald’s said Wednesday that customers should feel confident ordering from its restaurants despite a deadly E. coli outbreak linked to its Quarter Pounder hamburgers.

People are being interviewed by state and local public health officials about the foods they ate before they got sick. The 18 people interviewed all reported eating at McDonald’s with 16 eating a beef hamburger. Twelve people said they had eaten a Quarter Pounder.

McDonald’s said it has extensive food safety practices, and that nothing in the government’s investigation has indicated that there is an issue with its food preparation.

A Food Safety Expert at Mcdonald’s in the Era of E. Colic E. Calorimeter Reports to the Rutgers University Food Safety Investigation

Donald Schaffner, a food safety expert at Rutgers University, said that the symptoms of E. coli can be apparent in a couple of days. He said that if you ate these burgers in September you are probably okay because it is October and you didn’t get sick.

A contaminated product could have already made its way through the supply chain of Mcdonald’s. He said that the company will work closely with the government and cooperate with the investigation. Erlinger declined to name the supplier or say if it supplies other restaurant chains or grocery stores.
