A salmonella outbreak that sickened dozens of people last month has been linked to pre-cut melons from a food distributor in Indianapolis, spurring a recall of products in eight states.

Packages of fresh-cut watermelon, honeydew melon, cantaloupe and mixed fruit have been recalled in Georgia, Illinois, Indiana, Kentucky, Michigan, Missouri, North Carolina and Ohio. An investigation is underway to see if other products or states were affected.

So far, 60 people have been sickened by the outbreak — 32 were in Michigan — and at least 31 people have been hospitalized, according to the Centers for Disease Control and Prevention and the Food and Drug Administration. No deaths have been reported.
