France3.fr reports four children aged 2-14-years-old and one adult were hospitalized this week at Bordeaux University Hospital after suffering symptoms of E. coli. All reported eating hamburgers made by Société des Viandes Elaborées in Estillac although a direct link has not been established.

But that didn’t stop Intermarché and Netto supermarkets, who sold the steaks hamburgers, to recall some hamburger and ask their consumers to be vigilant.

A hotline has been set up: 0800 100 233.
