Causeway Bay dessert shop ordered to halt sales after food safety inspection reveals 280,000 Bacillus cereus per gram, sparking health warnings
HONG KONG – A beloved Causeway Bay bakery is under investigation after the Centre for Food Safety (CFS) detected dangerously elevated levels of Bacillus cereus in its popular Tieguanyin Basque cheesecake, prompting immediate sales suspension and a thorough sanitation overhaul. The routine inspection, announced on July 20, 2026, revealed bacterial counts nearly double the legal safety threshold, raising alarms over potential vomiting, diarrhea, and acute gastrointestinal distress among consumers.
What the Inspection Found
During a standard sampling operation, CFS officers collected a single sample of the Tieguanyin Basque cheesecake from an unnamed bakery in Causeway Bay. Laboratory results delivered a stark verdict: the cake contained 280,000 colony-forming units (CFU) of Bacillus cereus per gram—well above the 100,000 CFU per gram maximum considered acceptable under Hong Kong’s Microbiological Guidelines for Food.
This represents an exceedance of approximately 1.8 times the permitted limit, classifying the product as “unsatisfactory” under official food safety benchmarks.
Immediate Regulatory Action
Upon receiving the results, the CFS moved swiftly:
- Sales and disposal: The bakery was ordered to immediately cease sales and discard all remaining stock of the affected product.
- Sanitation and training: Staff received mandatory instruction on food safety and personal hygiene protocols. The premises, including kitchen and retail areas, underwent deep cleaning and disinfection.
- Ongoing investigation: The CFS confirmed that inquiries remain active. Under Section 54 of the Public Health and Municipal Services Ordinance (Cap. 132), selling food unfit for human consumption carries a maximum penalty of HK$50,000 and six months’ imprisonment.
The CFS has not publicly named the bakery. Journalists have reached out to suspected establishments but have yet to receive a response.
Understanding Bacillus cereus: A Hidden Threat in Baked Goods
Bacillus cereus is a spore-forming bacterium commonly found in soil, dust, and raw ingredients. It poses a particular risk in dairy-rich, high-moisture foods like cheesecakes, especially when temperature control fails.
How does it get into cheesecake?
According to food safety experts, contamination typically occurs during:
- Improper cooling: Cheesecakes left at room temperature for extended periods after baking provide an ideal breeding ground.
- Inadequate refrigeration: Storage above 4°C allows spores to germinate and multiply rapidly.
- Cross-contamination: Unsanitary handling or equipment can introduce bacteria post-baking.
Symptoms to watch for
Ingestion of high levels of Bacillus cereus—or its heat-stable toxins—can cause two distinct syndromes:
- Emetic (vomiting) form: Onset within 1–6 hours, often linked to rice and starchy foods.
- Diarrheal form: Onset within 8–16 hours, more common in dairy and meat dishes.
Both can lead to nausea, abdominal cramps, and dehydration, particularly in children, the elderly, or immunocompromised individuals.
Expert Tips: How to Stay Safe with Chilled Desserts
Hong Kong’s humid summer climate accelerates bacterial growth. The CFS and local health professionals advise consumers to adopt these precautions when purchasing and storing baked goods:
- Check storage conditions: Ensure the bakery keeps cheesecakes in a refrigerated display case at 4°C or below before purchase.
- Time matters: Consume refrigerated cakes within two hours of removal from cold storage. Do not leave them at room temperature for extended periods.
- Look for warning signs: Discard any product that exhibits off odors, a slimy texture, or excessive softness.
- Avoid overnight storage: Many foods lose nutritional value and accumulate harmful compounds when reheated or stored improperly.
Foods best consumed fresh
Health professionals emphasize that certain items should never be kept overnight:
- Leafy greens: High nitrate levels can convert to nitrites under bacterial action, posing health risks.
- Seafood: Protein breakdown may produce compounds irritating to the gut and liver.
- Mushrooms and white fungus: Also nitrate-rich; prolonged storage encourages nitrite formation.
- Starchy foods (potatoes, taro, bread): Susceptible to rapid bacterial growth; freeze leftovers if necessary.
Broader Implications for Hong Kong’s Food Culture
This incident serves as a timely reminder of the challenges facing Hong Kong’s vibrant dessert scene, where artisanal and chilled creations are increasingly popular. With the city’s dense population and high volume of food transactions, regulatory vigilance and consumer education are essential.
The CFS has not ruled out further legal action or expanded sampling of similar products across Causeway Bay and beyond. For now, the affected bakery is cooperating with authorities, and no additional contamination reports have emerged.
Consumers who have recently purchased Tieguanyin Basque cheesecake from any Causeway Bay outlet are encouraged to discard the product and monitor for symptoms. Anyone experiencing severe gastrointestinal distress should seek medical attention promptly.
