Central kitchens, food caterers, and restaurants were responsible for 55 food poisoning outbreaks between 2024 and 2025, according to the Communicable Diseases Agency (CDA). The rise in gastroenteritis cases is largely attributed to the centralized preparation of food, which increases the risk of contamination before mass distribution. Authorities are now ramping up monitoring and training to manage this trend.
Why Are Central Kitchens Linked to More Outbreaks?
The shift toward central kitchen models in sectors like schools and commercial catering has inadvertently created a higher risk environment. According to the CDA, the primary issue is the logistical challenge of preparing large quantities of food and holding them for extended periods before service. This window of time allows pathogens to proliferate, potentially affecting large groups of consumers simultaneously.
The CDA investigated 113 gastroenteritis outbreaks over the 2024–2025 period. Roughly two-thirds of these were linked to foodborne or waterborne pathogens.
How Is the CDA Detecting Pathogens Faster?
The National Public Health Laboratory has transitioned to using gastrointestinal polymerase chain reaction (PCR) panels to identify the cause of outbreaks. Lalitha Kurupatham, director of the CDA’s food and vector borne division, noted that this technology allows officials to detect multiple pathogens within hours. This is a significant upgrade from traditional culturing methods, which previously required days to deliver results.
What Happens When Food Safety Lapses Occur?
When an outbreak is reported, a team of nine public health officials inspects the premises and evaluates food handling processes. If staff members test positive for foodborne pathogens, they are suspended from duty. According to the CDA, these employees must provide two negative stool test results, taken at least a week apart, before they are cleared to return to work.
Businesses also face financial and operational penalties. Recent enforcement actions include:
- Yun Hai Yao: Fined $7,000 in July 2025 following an outbreak that affected 171 people, 60 of whom required hospitalization.
- Stamford Catering Services: Fined $8,000 in May 2026 after two separate outbreaks between October 2024 and February 2025 impacted 182 people.
Pro Tips for Food Safety at Home
While large-scale operators face strict regulations, the same principles of food safety apply in everyday life. Lalitha Kurupatham advises that the most effective way to prevent illness is to consume food shortly after it is cooked. If storage is necessary, food must be kept outside the “danger zone”—below 5 deg C or above 60 deg C.
Frequently Asked Questions
What are the most common pathogens in food poisoning?
The CDA identifies norovirus, salmonella, and Clostridium perfringens as the top three foodborne pathogens currently causing incidents.
What are the symptoms of gastroenteritis?
Common symptoms include nausea, vomiting, diarrhoea, and abdominal pain. Fever may occur, though it is less common with toxin-producing organisms.
How does the CDA prevent future outbreaks?
The agency monitors data trends and collaborates with partner agencies to publish joint advisories and conduct specialized training for food sector operators.
