Abstract
In September 2005, the first nationwide outbreak of Shiga toxin-producing Escherichia coli (STEC) O157 infections was observed. A total of 21 confirmed and 11 probable patients were reported, who fell ill between September 11 and October 10. Preliminary investigation by the local public health services revealed two possible risk factors: consumption of steak tartare and contact with other persons with gastroenteritis. The results of the subsequent case-control study suggested steak tartare as the most likely cause of the outbreak. Samples of steak tartare taken at a supermarket chain where most of the patients bought the product, tested negative for STEC O157. However, sampling took place 3 days after the date of symptom onset of the last outbreak case. Because 88% of the cases became ill within a two-week period and samples taken shortly afterwards tested negative, point source contamination of steak tartare was considered most plausible.
