Norovirus Concerns Rise in Gyeonggi Province Ahead of Lunar New Year
Amidst preparations for the Lunar New Year holiday, health officials in Gyeonggi Province are urging residents to exercise heightened caution regarding food safety, with a particular focus on preventing the spread of norovirus. Preliminary data indicates a significant proportion of suspected food poisoning cases in the region are linked to the highly contagious virus.
According to a statement released on Thursday, approximately 13.7% of the 2,120 (provisional) food poisoning cases reported in Gyeonggi Province in 2025 – a total of 291 patients – are presumed to be caused by norovirus. The winter months, spanning December 2024 to February 2025, saw a surge in infections, with 83 confirmed norovirus food poisoning cases.
Holiday Gatherings Increase Risk of Transmission
The approaching Lunar New Year holiday presents unique challenges to public health. Increased family gatherings and the preparation of large meals create ideal conditions for norovirus to spread through multiple pathways, including person-to-person contact, contaminated water sources, and the consumption of inadequately heated food.
Officials have identified several key risk factors contributing to potential outbreaks:
- Cross-contamination: Using the same cooking utensils – cutting boards, knives – for raw meats, fish, shellfish, and fresh vegetables.
- Improper Storage: Allowing large quantities of cooked food to sit at room temperature for extended periods.
- Temperature Negligence: Failing to maintain appropriate refrigerator and freezer temperatures, particularly during transportation.
- Insufficient Cooking/Reheating: Consuming food that has not been thoroughly cooked or failing to reheat stored food to a safe temperature.
Proactive Measures to Safeguard Family Health
To mitigate these risks, health authorities are emphasizing the importance of meticulous food handling practices. Residents are advised to utilize separate cutting boards and knives for different food groups, ensuring no cross-contamination occurs. Thorough handwashing after handling raw eggs or meat is also crucial to prevent the spread of germs.
Furthermore, cooked food should be cooled rapidly and stored in the refrigerator (at 5°C or lower) or freezer (at –18°C or lower) within two hours. Storing food in smaller containers facilitates faster cooling and minimizes bacterial growth.
“Since holiday food is directly related to family health, the most effective way to prevent food poisoning is to follow basic principles such as ‘not leaving it unattended after cooking, keeping it cold, and cooking it thoroughly before eating,’” stated Jeong Yeon-pyo, head of Gyeonggi Province’s Food Safety Department.
These guidelines, while seemingly simple, represent a critical line of defense against a potentially disruptive and unpleasant outbreak during a time traditionally dedicated to family and celebration.
