ATLANTA (AP) - Health officials say the death of an Arizona resident who recently traveled to Germany may be linked to the food-poisoning outbreak in Europe.

The Centers for Disease Control and Prevention on Thursday said the death is under investigation. The Arizona resident had a severe E. coli complication that can lead to kidney failure.

If confirmed, it would be the first U.S. death tied to the outbreak.

So far, there have been five confirmed cases in the United States connected to the outbreak. Those cases are in Michigan, Massachusetts, Wisconsin and North Carolina.

Officials have traced the outbreak to raw vegetable sprouts from a farm in northern Germany.
