McDonald's says it has stopped offering slivered onions in the affected states. Additionally, Taylor Farms, a supplier of onions for the fast food chain, has initiated a voluntary recall.
The CDC says the 15 new E. coli cases occurred before McDonald's and Taylor Farms took action.
"Due to the product actions taken by both companies, CDC believes the risk to the public is very low," the CDC said on Wednesday.
Some people are more at risk of E. coli infection than others.
They include young children, adults 65 years and older and people with a weakened immune system, according to the CDC.
Signs of E. coli infection include diarrhea and a fever higher than 102°, vomiting and dehydration.
In serious cases, kidney failure and death can occur.
