McDonald’s South Korea has ceased the sales of its Bulgogi burgers on Saturday after several customers showed positive symptoms of enteritis – an inflammation of the intestine that usually causes diarrhea.

In the Aug 25 incident, seven grade school students and a teacher suffered stomach aches and high fever after they had allegedly eaten bulgogi burgers at an outlet in Jeonju.

Following the complaints of serious health issues, McDonald’s Korea said it would remove the iconic Korean burgers off the menu for time being.

McDonald’s Korea also agreed to cooperate with the Ministry of Food and Drug Safety in determining the exact cause of the health issues faced by the customers.

"The decision to halt the sales of bulgogi burgers is a pre-emptive action while waiting for the MFDS examination results to come out.

“McDonald's Korea wishes the affected customers a quick recovery," the company said in a press release.

In July, complaints were made against the American fast-food chain over undercooked hamburger patties, which caused at least one customer to become ill.
