Public health officials are investigating a “fast-moving” outbreak of Escherichia coli, or E. coli, that has sickened at least 15 people in Michigan and 14 in Ohio, the Centers for Disease Control and Prevention (CDC) announced (opens in new tab) Wednesday (Aug. 17).
So far, nine people out of the 29 infected have required hospitalization but no one has died.
The strain of E. coli that appears to be driving the outbreak is known as E. coli O157:H7. This type of bacteria produces a poison called Shiga toxin that can cause severe gastrointestinal symptoms, side effects with taking celexa including abdominal cramps, vomiting and bloody diarrhea, the CDC stated (opens in new tab). In some cases, E. coli O157:H7 infections can lead to a serious complication called hemolytic uremic syndrome (HUS), which damages the red blood cells and kidneys and can result in kidney failure and death, according to Johns Hopkins Medicine (opens in new tab). Children and elderly people have an elevated risk of HUS.
Public health officials are now working to identify any additional cases of illness linked to the outbreak, while also interviewing people about the foods they ate in the week before they got sick. The food source of the outbreak has yet to be identified, but based on the DNA of E. coli sampled from infected individuals, it’s likely that they all became ill from eating the same food because the bacterial strains appear very closely related, the CDC stated.
Some recent E. coli cases in Michigan and Ohio have yet to be added to the CDC’s PulseNet system, a national database of DNA fingerprints of bacteria that cause foodborne illnesses, so the CDC’s tally is expected to increase soon. The Michigan Department of Health and Human Services (MDHHS) has received 98 reports of E. coli infection this August, as compared to only 20 cases reported during the same time period in 2021, according to a statement (opens in new tab).
“While reports of E. coli illness typically increase during the warmer summer months, this significant jump in cases is alarming,” Dr. Natasha Bagdasarian, chief medical executive of MDHHS, said in the statement. “This is a reminder to make sure to follow best practices when it comes to hand hygiene and food handling to prevent these kinds of foodborne illness.”

The CDC advises calling your healthcare provider right away if you have any of these severe E. coli symptoms:
- Diarrhea and a fever higher than 102 degrees Fahrenheit (38.9 degrees Celsius)
- Diarrhea for more than 3 days that is not improving
- Bloody diarrhea
- So much vomiting that you cannot keep liquids down
- Signs of dehydration, such as not peeing much; dry mouth and throat; or feeling dizzy when standing up
Symptoms of E. coli tend to appear within one to 10 days of exposure, with most people falling ill within three to four days of swallowing the bacteria, according to the CDC. The majority of people recover in five to seven days without the need for treatment, but those with severe infections and complications like HUS may require hospitalization.
The following safety tips can help prevent E. coli infections:
- Clean: Wash your hands, utensils and surfaces often. Rinse fruits and vegetables under running water before eating, cutting or peeling.
- Separate: Keep food that won’t be cooked separate from raw meat, poultry and seafood.
- Cook: Use a food thermometer to make sure you have cooked your food to a temperature high enough to kill germs.
- Chill: Refrigerate perishable food (food that goes bad) within 2 hours. If the food is exposed to temperatures above 90 F (32 C), for instance in a hot car or at a picnic, refrigerate within 1 hour. Thaw food in the refrigerator, not on the counter.
“If a [contaminated] food item is identified, investigators will issue advice for people and businesses,” the CDC says.
