What is E. coli?
Escherichia coli (E. coli) is a diverse group of bacteria, some of which live harmlessly in the intestines of humans and animals. However, certain strains, like E. coli O157, can cause severe illness. These harmful strains produce toxins that can damage the lining of the small intestine, leading to symptoms like severe abdominal cramps, bloody diarrhea, and vomiting.
Symptoms and When to Seek Medical Attention
Symptoms of an E. coli infection typically begin 3-4 days after exposure, but can range from 1 to 10 days. If you have eaten at McDonald's recently and experience any of these symptoms, especially after consuming a Quarter Pounder, it's important to contact a healthcare provider.
Common symptoms include:
- Severe stomach cramps
- Diarrhea, which may often be bloody
- Vomiting
- Mild fever
In some severe cases, E. coli infection can lead to a serious complication called hemolytic uremic syndrome (HUS), a type of kidney failure. HUS is most common in young children and the elderly. Seek immediate medical care if you or someone you know develops signs of HUS, such as decreased urination, unusual bruising, or pale skin.

Preventing E. coli Infection
While investigations are ongoing to pinpoint the exact source of outbreaks, general food safety practices are crucial for preventing E. coli and other foodborne illnesses:
- Practice Good Hand Hygiene: Wash hands thoroughly with soap and water before and after handling food, after using the restroom, and after contact with animals.
- Cook Meats Thoroughly: Ground beef should always be cooked to an internal temperature of 160°F (71°C). Use a food thermometer to ensure safety.
- Prevent Cross-Contamination: Keep raw meats separate from other foods, and use separate cutting boards and utensils for raw and cooked items.
- Wash Produce: Rinse fruits and vegetables thoroughly under running water, even if you plan to peel them.
- Avoid Unpasteurized Products: Steer clear of unpasteurized milk, juices, and ciders.
