Tips to help manage food recalls and prevent foodborne illnesses

About 128,000 are hospitalized and 3,000 people die each year from preventable foodborne illnesses.


  • At least 29 people fell ill due to an E. coli outbreak in Michigan and Ohio.
  • The CDC is investigating the outbreak, but no cause has been determined.
  • Health officials advise people practice safe food handling as the outbreak could easily spread.

Dozens of people in Michigan and Ohio have fallen ill to a “fast-moving” E. coli outbreak, and the Centers for Disease Control and Prevention has not found a cause. 

There have been 29 reported cases of E. coli illness in the two states since July 26, with 15 in Michigan and 14 in Ohio, according to CDC data. The ages of ill people range from six to 91 years old, and at least nine people have been hospitalized. No deaths have been reported.

However, officials believe the number of sick people is “likely higher,” and the bacteria could be outside of the two states since it usually takes up to four weeks to determine if an illness is part of an outbreak, and sometimes people don’t require medical attention.

Cause of Michigan, Ohio outbreak unknown, CDC says

E. coli typically gets transmitted to humans through contaminated foods, but the CDC has yet to find the cause of the current outbreak. 

Early findings from the investigation “showed that bacteria from sick people‚Äôs samples are closely related genetically. This suggests that people in this outbreak got sick from the same food.”

The outbreak comes as the Michigan Department of Health and Human Services announced on Tuesday it was investigating 98 cases of E. coli illness, including ones not part of the CDC investigation. In comparison, there were only 20 cases in the same time period in 2021. 

“While reports of E.coli illness typically increase during the warmer summer months, this significant jump in cases is alarming,” said Dr. Natasha Bagdasarian, MDHHS chief medical executive, in a statement.

E. coli symptoms 

Symptoms of E. coli vary, but common ones include a fever, diarrhea, stomach cramps and signs of dehydration, the CDC says.

Symptoms often start 3 to 4 days after swallowing the bacteria, per the CDC.

If you or someone you knows appears to have an E. coli infection, the CDC recommends writing down what the person ate in the week prior, and reported it to state health officials. 

E. coli prevention tips

In the meantime, the CDC says prevention tips for E. coli include proper hand hygiene and food handling practices. That includes washing hands with water and soap before and after handling food, using the bathroom and having contact with animals and their environments. 

Officials also advise not letting raw meat, poultry and eggs or cooked food sit at room temperature for more than two hours, to not place cooked food on a plate that was holding raw meat or poultry, cooking meat thoroughly and rinsing fruits and vegetables.
