Over 1,000 people, mostly school children, got sick across the nation after eating a chocolate cake distributed by a Pulmuone affiliate, local health authorities announced Friday.
No serious illnesses have been reported, although some victims are receiving medical treatment in hospitals. 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 as of 9 a.m. on Friday, said the ministry.
Most persons infected with salmonella develop diarrhea, fever and abdominal cramps 12 to 72 hours after infection, according to descriptions from the Centers for Disease Control and Prevention. The illness usually lasts four to seven days and most people recover without treatment.
Pulmuone said it recalled the chocolate cake and halted all distribution and sales of the product.
Among those who allegedly came into contact with the disease, 545 did so in seven locations in Busan; 167 in four locations in Daegu; nine in the same location in Ulsan; 31 in the same location in Gyeonggi; 163 in seven locations in North Jeolla; 98 in three locations in North Gyeongsang; and 143 in six locations in South Gyeongsang.
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.
