Lee Sung-Eun of the Korea JoongAng Daily reported last month that over 1,000 people, mostly school children, got sick across the nation after eating a chocolate cake distributed by a Pulmuone affiliate.
The Ministry of Food and Drug Safety said Salmonella, a common type of food-poisoning bacteria, was detected in the cake.
A total of 1,156 people who ate the dessert in 29 cafeterias across the nation, mostly in schools, reported symptoms of food poisoning.
Pulmuone said it recalled the chocolate cake and halted all distribution and sales of the product.
The product, Chocolate Blossom Cake, was made by the W1FNB food company in Goyang, Gyeonggi, and distributed by Pulmuone Foodmerce, which has its headquarters in Yongin, Gyeonggi.
