At least two children in the greater Sacramento region are battling against kidney failure as a result of an E. coli outbreak related to eating romaine lettuce, which the Centers for Disease Control and Prevention has issued a warning for.

The mother of a teenage girl from Wilton told KCRA 3 that her daughter is in the intensive care unit at Kaiser Permanente in Roseville suffering from kidney failure after she ate the lettuce.

The mother added that she knows of at least one other child -- a 6-year-old boy -- suffering from similar kidney symptoms relating to the E. coli outbreak.

The CDC issued an alert earlier in April, urging people to not eat romaine lettuce and throw the vegetable away if you have it in your home due to the concern over E. coli.

Although the source of the E. coli has been traced back to Yuma, Arizona, officials have not been able to confirm exactly where the lettuce was harvested from in that region.

Therefore, the CDC said unless people can confirm exactly where the romaine lettuce is from, no one should be eating it. Most packaging doesn't list from which areas the lettuce was grown.

There have been 84 confirmed cases of E. coli related to the lettuce across nearly a dozen states, and 42 people have been hospitalized with severe symptoms.

Pennsylvania leads the country with 18 cases, while California is second with 13 cases, according to the CDC.
