The Centers for Disease Control is issuing a warning to consumers not to eat some Fresh Express Sunflower Crisp Chopped Salad Kits due to another E. coli outbreak. 

Federal health officials said Monday that it is investigating eight infections in Minnesota, North Dakota and Wisconsin. Additionally, the CDC said Canada has reported 16 people infected with the same E. coli strain. 

This particular outbreak is caused by a different strain of E. coli than another outbreak currently linked to romaine lettuce from the Salinas, California, growing region. The CDC noted that while romaine lettuce is one of the ingredients in the Sunflower Crisp salad kits, they're still working to determine what ingredient in the kit was contaminated. 

Consumers will have to look for this identifying information to know if they have one of the products that are possibly contaminated.
