Buitoni Pizzas have been identified as the source of an extensive outbreak of hemolytic uremia syndrome (HUS) by health authorities in France. Agencies including Sante Publique and the Directorate General for Public Health have investigated sporadic E. coli O26 with fifty-eight cases identified in twelve regions.  Traceback studies implicated Fraich'Up Pizzas distributed under the Buitoni brand owned by multinational Nestle.  Following disclosure of the results of the investigation, the implicated pizzas have been recalled.  Concurrently Buitoni Pizzas have been recalled in Slovenia and Luxembourg by supermarket chains based in France.

The source of the contamination has not been determined but is obviously under intensive investigation by Buitoni.
