(CNN) — A salmonella outbreak that’s sickened 18 people in six states is linked to Papa Murphy’s raw chocolate chip cookie and S’mores bar dough, the US Centers for Disease Control and Prevention said Tuesday. Two people have been hospitalized. No deaths have been reported.

Health officials are speaking with ill people about what they ate in the week before they got sick, and of the 14 interviewed, 12 reported eating food from Papa Murphy’s, the CDC says. Nine of them ate raw cookie or S’mores bar dough, and one ate baked cookies made with the dough.
