A concerning E. coli outbreak has been linked to McDonald’s. It has affected multiple states, killed one individual, and sickened dozens more.
The Centers for Disease Control and Prevention (CDC) is now investigating the outbreak, with an early focus on McDonald’s Quarter Pounder hamburgers as the likely source.
Here’s a closer look at what’s known so far, how the outbreak is being handled, and what customers need to know to stay safe.
Overview of the E. Coli Outbreak
As of October 22, the CDC reports that 49 people have been sickened by this E. coli outbreak, with cases spread across ten states:
- Colorado
- Kansas
- Utah
- Idaho
- Iowa
- Missouri
- Montana
- Nebraska
- Nevada
- New Mexico
Among these cases, ten people have been hospitalized, and one individual has tragically died. The outbreak primarily involves customers who recently ate McDonald’s Quarter Pounder burgers, which led to a focus on the potential contamination of a common ingredient.
Possible Source: Slivered Onions in Quarter Pounders
While it remains unclear which ingredient might be contaminated, McDonald’s Chief Supply Chain Officer Cesar Piña shared some initial findings in a statement on October 22.
Piña mentioned that slivered onions, used in the Quarter Pounder, maybe a potential culprit. These onions were sourced from a single supplier who distributes them to several states now impacted by the outbreak.
To help contain the outbreak, McDonald’s has halted using these slivered onions in the affected locations, following CDC recommendations. The company also temporarily removed the Quarter Pound from the menu in many locations within the impacted states.
States Impacted by Quarter Pounder Removal
In response to this potential link, McDonald’s has pulled Quarter Pounders from restaurants across several states where cases have been reported. This temporary removal affects the following areas:
- Colorado
- Kansas
- Utah
- Portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, and Oklahoma
McDonald’s assures customers that food safety is its top priority, and the company is working closely with the CDC to manage the situation.
Other McDonald’s Menu Items Not Affected
The outbreak is limited to the Quarter Pounder and does not involve other McDonald’s beef products. Other popular menu items include:
- Cheeseburgers (300 calories)
- Hamburgers (250 calories)
- Big Macs (590 calories)
- McDoubles (390 calories)
- Double Cheeseburgers (440 calories)
These menu items are still available and unaffected by the E. coli outbreak, allowing McDonald’s customers to enjoy other meals. At the same time, the Quarter Pounder remains off the menu in specific locations.
McDonald’s Actions in Response to the Outbreak
In addition to temporarily removing the Quarter Pounder from impacted areas, McDonald’s is collaborating with the CDC to understand how the contamination may have occurred.
The company is also working with its suppliers to implement additional safety checks, aiming to safely restore Quarter Pounder ingredients to affected regions.
Piña mentioned that McDonald’s is committed to providing updates as the situation progresses. Customers can expect news on when the Quarter Pounder may return to their area, although this timeline will vary depending on the investigation’s results.
What is E. Coli, and How Does it Spread?
E. coli is a group of bacteria that can harm humans, often spreading through contaminated Food or water. Some of the most common ways people become infected include:
- Eating contaminated Food
- Drinking untreated water
- Contact with animals or infected individuals
- Exposure to contaminated surfaces
Certain groups are at higher risk for E. coli infections, particularly:
- Children under five
- Older adults (65+)
- People with weakened immune systems
- International travelers who may encounter contaminated Food or water
Symptoms of E. Coli Infection
Symptoms of an E. coli infection often begin with stomach pain and may develop further over several days. In severe cases, symptoms can include:
- High fever (above 102°F)
- Bloody diarrhea
- Persistent diarrhea lasting three days or longer
- Vomiting that prevents keeping liquids down
- Signs of dehydration (dry mouth, reduced urination, dizziness)
In this outbreak, the CDC recommends that anyone who has recently eaten a quarter pound and experiences any of these symptoms should contact their healthcare provider as soon as possible.
Tips for Preventing E. Coli Infection
To help protect yourself from E. coli, here are a few safety tips to consider, especially during outbreaks:
1. Handle Food Carefully: Wash hands, utensils, and surfaces with soap and water when preparing Food, particularly Meat.
2. Cook Meat Thoroughly: Ensure beef and other meats are cooked to safe internal temperatures to kill bacteria.
3. Avoid Raw or Unpasteurized Products: Consuming raw milk or unpasteurized juices increases your risk of infection.
4. Stay Hydrated and Wash Hands Regularly: Drinking water helps flush bacteria from your system, and frequent handwashing reduces contamination risks.
What’s Next? McDonald’s and CDC’s Continued Investigation
The CDC and McDonald’s focus on identifying the exact source of the contamination. McDonald’s is working on supply chain adjustments and reinforcing quality checks with suppliers to ensure safe Food reaches customers.
Although the return of the Quarter Pounder in affected states may take some time, McDonald’s has promised to keep customers informed as they navigate these changes. For now, the company’s priority remains the health and safety of its customers.
