A safety evaluation by the Hong Kong Consumer Council on 30 beer products revealed the presence of the mycotoxin deoxynivalenol (DON), commonly known as vomitoxin, in Harbin Beer McDonnell Douglas, with a concentration of 26 micrograms per kilogram, which is below the Chinese national safety limit of 1000 micrograms per kilogram. Despite being within safe limits, excessive consumption of DON can cause symptoms like vomiting and abdominal pain. Following this discovery, South Korea's Food and Drug Administration, which currently lacks specific regulations for DON in beer, has announced it will enhance customs inspections for Harbin beer imported from China to ensure consumer safety.
