On 30 July 2024, what should have been an ordinary catered lunch at ByteDance’s Singapore office at One Raffles Quay turned into one of the most alarming food safety incidents the country had seen in years. A total of 171 people reported gastroenteritis symptoms after consuming food catered by Yun Hai Yao’s Northpoint City outlet.

The suffering was severe — 60 victims were hospitalised, of which 22 were warded for between one and three days, while another 38 were treated at the hospital and given medical leave.

Investigations by the Singapore Food Agency (SFA) revealed a chilling picture of what had gone wrong. A chicken dish contained coagulase-positive Staphylococcus aureus with genes for Staphylococcus Enterotoxin A, a toxin-producing bacterium that can cause food poisoning when hygiene standards are not maintained during food preparation.

And that was not all. The day after the food poisoning incident, more than 10 live cockroaches were found at the premises of Yun Hai Yao’s Northpoint City outlet during a joint inspection by SFA and the Ministry of Health.

The incident is a stark reminder that food safety failures are never just technical slip-ups — they are deeply human consequences. When bacteria multiply in food that is improperly stored or cooked, people pay the price with their health, their time, and in the worst cases, their lives.

Why Vigilance Cannot Be Switched Off When Handling Food

The caterer later noted that due to insufficient temperature and time control during storage and delivery, this led to the growth of microbes in the dishes. This single lapse — something as seemingly manageable as temperature control — sent ambulances rushing to a corporate office in Singapore’s CBD. The lesson here is sobering: food safety is not a one-time checklist. It is a continuous discipline that must be practised at every single stage of the food chain, from procurement and preparation to packaging and delivery.

Professional food handlers must understand the science behind what they do. Bacteria like Staphylococcus aureus thrive when cooked food is left in the “danger zone” — between 5°C and 60°C — for too long. Without proper training, these invisible threats go undetected until it is far too late.

PRACTICAL FOOD SAFETY TIPS
Here are essential practices every food handler should follow to prevent similar tragedies:

• Control food temperature strictly. Hot food must be kept above 60°C and cold food below 5°C at all times. Never leave cooked food at room temperature for more than two hours.
• Practise rigorous personal hygiene. Wash hands thoroughly with soap before and after handling food, especially after handling raw meat.
• Keep raw and cooked foods separate. Cross-contamination is one of the leading causes of food poisoning.
• Maintain a pest-free kitchen. Regular pest inspections are essential — cockroaches and rodents can contaminate food surfaces with bacteria.
• Clean and sanitise equipment regularly. Countertops, knives, chopping boards and utensils must be sanitised consistently.

Be Equipped — Not Just Well-Meaning

Good intentions are not enough in a professional kitchen or catering operation. You need certified knowledge. The Food Safety Course Level 1, approved by the Singapore Food Agency (SFA), equips food handlers with the foundational skills and awareness to prevent exactly the kind of tragedy that unfolded at ByteDance in 2024.

Whether you are a hawker stall assistant, a catering supervisor, or an F&B manager, being certified is not just a regulatory requirement — it is your commitment to the people who eat your food.
