Two people in Kentucky have become ill with this strain of Salmonella. The outbreak began on June 8, prompting Caito Foods, LLC to recall precut watermelon, honeydew melon, cantaloupe and fruit medley products produced at the Caito Foods facility in Indianapolis.
Earlier this year, 210 people were infected by an E. coli outbreak that killed five people linked to romaine lettuce that had been grown in Arizona.
Of those victims who were interviewed about what they ate, the most cited cereal was Honey Smacks.
Salmonella symptoms include diarrhea, fever, and abdominal cramps within about 12 to 72 hours of exposure.
Symptoms last about four to seven days, and although most people improve without treatment, some may require hospitalization because of severe diarrhea.
