[Large-scale, acute, bacterial gastroenteritis caused by the enterotoxin of Staphylococcus aureus after a barbecue]. / Grootschalige, acute bacteriële gastro-enteritis door enterotoxine van Staphylococcus aureus na een barbecue.

UNLABELLED: EPIDEMIOLOGICAL OBSERVATION: On a warm day, during a barbecue that was attended by over 100 guests, a large number became rapidly ill with signs of acute gastroenteritis within a few hours after eating the prepared food. The characteristic symptoms were nausea, vomiting, syncope and in some cases in a later stage, diarrhoea. Sixty patients were transferred to hospitals. INVESTIGATION: Investigation revealed that the cause of this outbreak of gastroenteritis was an enterotoxin-A-producing strain of Staphylococcus aureus in a noodle dish. Both the food residues and the faeces from patients contained genotypically identical strains of S. aureus. They all had the gene for the gastroenteritis-inducing enterotoxin A from S. aureus. CONCLUSION: This case shows that the timely involvement of the different health authorities responsible for intervening in explosions of food poisoning is crucial for the clarification and treatment of such large-scale outbreaks. In the investigation of this outbreak, the municipal health authority co-operated with regional laboratories and the Food and Consumer Product Safety Authority/Inspectorate for Health Protection and Veterinary Public Health.
