The decision was made after food poisoning was reported at 13 schools across the country, including those in North Jeolla, North Gyeongsang and Gyeonggi provinces and Busan, where the cake had been served as part of lunch for students.
Authorities subsequently found salmonella in the cakes manufactured by a small cake maker based in Gyeonggi Province. Salmonella bacteria can cause diarrhea and vomiting, among other symptoms. Schools have been informed of the outbreak, they added.
