Update on food poisoning incidents (11 April)

11 Apr 2009

'Rojak Geylang Serai' at Geylang Serai Temporary Market

1. Since 9 April, there were no further notified cases to MOH and the total number of food poisoning cases remains the same at 154, with 48 cases hospitalised. Two more patients have been discharged, with 3 patients still recovering in the hospitals. Their conditions are stable. All notified cases had reported their onset of illness in the period from 1st to 4th April. It appears that the transmission had ceased following the immediate closure of the food stall on 4 April.

2.  Investigations point to this incident as a common source outbreak of V. parahaemolyticus food poisoning traced to the consumption of rojak from the "Rojak Geylang Serai" food stall, most likely due to cross-contamination of rojak and raw seafood ingredients harbouring the bacteria.

3. Laboratory results of 3 food handlers, including a food handler from the mee siam stall, are still pending.

4.  Vibrio parahaemolyticus is a bacteria that causes watery diarrhoea and abdominal cramps in nearly all cases, usually with nausea, vomitting, fever and headache. Typically, it is a disease of moderate severity lasting 1 - 7 days. Systemic infection and death rarely occur. Food poisoning is generally not contagious but faecal-oral transmission can occur with poor personal hygiene.

None were hospitalised. MOH and NEA are investigating into the incident.

6 Members of the public who have patronised the restaurant and are experiencing symptoms of food poisoning should seek immediate medical attention.
