In late 2023, a mass gastroenteritis outbreak quietly unfolded across Singapore, linked to a single catering company. Between November and December 2023, the Ministry of Health and Singapore Food Agency received reports of a mass gastroenteritis incident involving 395 individuals who had eaten food catered by Shiok Kitchen Catering. Investigations at the company’s facility revealed multiple food safety violations, including a particularly troubling finding: a food poisoning-causing bacterium, Bacillus cereus, was present in a spinach dish doused with garlic cream sauce.

SFA found the firm had flouted multiple food safety regulations, including preparation of food unsafe for human consumption and failure to ensure a clean facility. The company was fined $8,000 and its operations were suspended from December 14, 2023 to January 5, 2024.

Nearly 400 people sick. A kitchen that failed basic cleanliness standards. A bacterium that should never have been in a finished dish served to paying customers. The numbers are alarming — and yet, this incident received far less public attention than the ByteDance or Spize cases. That is precisely the danger: food safety failures do not always come with flashing warning lights. Sometimes they accumulate quietly, in dirty corners and unmonitored kitchens, until hundreds of people are suddenly ill.

The Invisible Threat of Bacillus Cereus

Bacillus cereus is a particularly insidious bacterium because it is found naturally in the environment — in soil, on vegetables, and in starchy foods like rice and pasta. It becomes dangerous when food is cooked and then left to cool slowly, allowing bacterial spores to germinate and multiply. Reheating food does not always destroy the toxins that Bacillus cereus produces, which means that proper storage temperature and timing are critical lines of defence.

Many food handlers are unaware of this risk because Bacillus cereus does not smell or look different. There is no visual cue that the food is contaminated. Only proper training, proper cooking temperatures, and proper food storage practices stand between a delicious meal and a medical emergency.

Don’t Let Your Business Become a Statistic

SFA reminded food establishments that food can be contaminated anywhere along the food chain, and that the industry must play its part alongside regulatory enforcement. That means training is not a box to tick — it is an ongoing culture that every F&B operator and food handler must embrace.
