Nineteen cases of infection with E. coli O157 have been detected in Limburg, Belgium, of which three have developed hemolytic uremic syndrome (HUS).
The Federal Agency for Security of the Food Chain (AFSCA) said Thursday that all cases are related to the ingestion of filet américain (lit. American fillet) with onions and more seasoning than a normal steak tartare.
AFSCA launched an investigation and based on date of purchase, consumption and onset of disease, the suspect beef has been traced and initial sampling results were positive for E. coli O157.
