The institute collects groundwater samples annually from food manufacturers, restaurants, and social welfare facilities located in Busan to analyze norovirus genes, aiming to prevent mass food poisoning outbreaks and strengthen hygiene management. Each year, different facilities are surveyed to address hygiene blind spots.

This investigation was conducted from February to April this year, targeting 20 local food manufacturers, restaurants, and social welfare facilities using groundwater as food water, and norovirus was not detected in any of the surveyed establishments, indicating safety.

Norovirus, a representative pathogen causing food poisoning, can survive at low temperatures below minus 20℃. This virus is known as a major cause of food poisoning incidents especially in winter, with main symptoms including diarrhea, vomiting, abdominal pain, and fever.

From winter to spring, the risk of food poisoning caused by norovirus increases, so special attention to personal hygiene and food sanitation management is necessary.

Since norovirus is highly contagious between people, if infection is confirmed among workers in mass catering facilities or restaurants, they should immediately stop participating in food preparation and refrain from cooking activities for 2 to 3 days after recovery to prevent the spread of norovirus.

An official from the Health and Environment Research Institute stated, “Regular water quality testing and hygienic management of groundwater wells are necessary to prevent norovirus contamination in groundwater. Mass catering facilities are recommended to install disinfection devices in groundwater storage tanks, and if groundwater is used as drinking water, it must be boiled before consumption.” They added, “Since there are no vaccines or treatments for norovirus infection, thorough personal hygiene such as handwashing is the best prevention.”
