This October, the CDC confirmed an E. coli outbreak connected to the McDonald’s Quarter Pounder. Dozens of people across the U.S. fell sick, with ten being hospitalized and one dying. Unfortunately, E. coli outbreaks occur every year, often multiple times. It is estimated that 266,000 people are infected annually, leading to over 3,600 hospitalizations and 30 deaths.

Luckily, by taking simple precautions, it’s easy to protect your health. Here’s everything to know about the symptoms and safety measures associated with E. coli.

What is E. coli?

While commonly used to refer to the illness it causes, Escherichia coli (E. coli) is a group of bacteria typically found in the intestines. Most of these bacteria are not only harmless, but important for our gut health. However, certain strains can lead to severe foodborne illness, including those such as Shiga toxin-producing E. coli. Outbreaks can occur when these harmful bacteria contaminate sources of food and water, or through human contact with an infected animal. Past outbreaks have been linked to leafy greens, raw or undercooked meats, raw milk, and impure water​. 

Warning Signs of Infection

Symptoms of E.coli typically present themselves 1-10 days after exposure to bacteria. They include stomach cramping, diarrhea, vomiting, nausea, fever, and, in severe cases, bloody stool. Depending on the type of pathogen, these symptoms may intensify, leading to life-threatening issues such as high blood pressure or hemolytic uremic syndrome (HUS), which affects the kidneys.

Children under the age of five, older adults, and immune-compromised individuals are at a higher risk of severe symptoms if infected.

Avoiding E. coli

The most important steps to reducing risk of E.coli infection are to prioritize food safety and good hygiene. Be sure to:

• Cook Foods as Instructed — Undercooked food is one of the leading sources of E. coli infection, especially meat. Cook eggs and all ground meats to 160°F, poultry, and fowl to 165°F, and fresh meat steaks, chops, and roasts to 145°F.
• Wash Your Hands — Practice good hygiene by washing with warm water and soap for at least 20 seconds before eating, after using the bathroom, or when handling food.
• Clean Your Produce – Rinse your produce thoroughly before eating or buy pre-washed produce.
• Prevent Cross-contamination — Utilize separate utensils, dishes, and cutting boards for raw meat and produce. Also, regularly clean your surfaces and utensils as you cook.
• Filter Your Water — Drink water from safe sources or utilize filtration systems if needed. Avoid swallowing water when swimming. 

When E.coli outbreaks occur, the CDC or FDA will issue guidance on how best to stay safe. Regularly check these sources to stay informed on infected foods, product recalls and returns, and symptom monitoring.
