Health officials are warning the public after a salmonella outbreak was reported in Illinois linked to BrightFarms Sunny Crunch salad. Some cases have been reported in McHenry County.

The Illinois Department of Public Health (IDPH) said they are working with local health departments, the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to investigate a multi-state outbreak of Salmonella Typhimurium.

The outbreak is linked to BrightFarms brand Sunny Crunch salad, which is produced in Rochelle.

According to the CDC, eight people infected with the outbreak strain of Salmonella Typhimurium have been reported from two states.

Illnesses started on dates ranging from June 10 to June 15. In Illinois, five cases matching the outbreak strain have been reported in Cook, DuPage and McHenry counties.

Illinois cases have reported purchasing BrightFarms Sunny Crunch salad in the northeastern part of the state.

No one has been hospitalized or died from the outbreak, according to the CDC.

IDPH said they are still working with federal officials to determine where in Illinois the salad was distributed. People throughout the state could potentially be exposed, IDPH said.

The salad was also distributed to Indiana, Iowa and Wisconsin.

Symptoms of illness caused by Salmonella may include headache, muscle aches, diarrhea, vomiting, abdominal cramping, chills, fever, nausea and dehydration.

Health officials say that anyone who experiences these symptoms 12-72 hours after eating BrightFarms Sunny Crunch salad, produced in Rochelle, should contact their health care provider and let them know.

Anyone who purchased the above-mentioned salad should not eat it and instead throw it away. Surfaces and containers that may have touched the contaminated products should be washed using hot and soapy water.
