Food Safety News reports that an outbreak of E. coli O157:H7 in Michigan has been genetically matched to one in Ohio, where health officials are currently investigating at least four similar cases.
The case count in Ohio includes three in Lucas County and one in Portage County and involves adults ages 19 to 42 years.
The five Michigan cases include adults ages 20 to 41 from the following five counties: Oakland, Washtenaw, Ken, Livingston and Ottawa. A woman from the Grand Traverse region may be a sixth case after recently traveling to Grand Rapids, where she ate ground beef.
Those sickened in Michigan indicated to health officials that they had consumed undercooked hamburger prior to developing symptoms. Michigan health officials have reportedly been trying to track down the source of the meat.
According to the Michigan Department of Community Health, three of the five people sickened in that were hospitalized.
Symptoms of E. coli infection can vary from person to person but often include severe stomach cramps, diarrhea, and vomiting. Most people get better within five to seven days. Some infections are very mild, but others are severe or can even be life-threatening.
