Health departments in Michigan on Friday are warning consumers about pre-cut melons from Walmart or Kroger stores that are suspected in an outbreak of salmonella. 

The Michigan Department of Agriculture and Rural Development and Michigan Department of Health and Human Services are working with the U.S. Food and Drug Administration and the Centers for Disease Control and Prevention to investigate a multistate outbreak of salmonella adelaide linked to cut melons, health  officials said.

"Most people who have been infected with this strain of salmonella bought pre-cut melon at Walmart or Kroger stores in the Midwest," according to a news release.

Consumers who bought  pre-cut melons, including watermelon, muskmelon, cantaloupe andfruit salad mixes with melon, are urged to throw the melons away. 

"Walmart and Kroger are cooperating fully with the investigation and have removed all cut melon associated with this outbreak," according to the release. "The CDC is not recommending people avoid whole melons."

Since April 30, an outbreak has been reported in five states and infected 60 people, including 32 cases in Michigan. 

Of the 60 cases reported in Michigan, 31 have been hospitalized due to illness associated with the infection. No deaths have occurred. Other states that have reported illnesses as part of the outbreak include Illinois (6 cases), Indiana (11 cases), Missouri (10 cases) and Ohio (1 case). 

Most people infected with salmonella develop diarrhea, fever and abdominal cramps 12 to 72 hours after being exposed to the bacteria. The illness usually lasts four to seven days and most people recover without treatment, according to the FDA.

"This investigation is expanding rapidly," according to the release. "The FDA is working to identify a supplier of pre-cut melon to stores where ill people shopped. CDC’s advice to consumers may expand to include other stores where contaminated pre-cut melon was sold."
