Genoa salami was the most probable cause of an outbreak of E. coli O157:H7 infections in Canada. The salami was made using a dry fermentation process by the Venetian Meat and Salami Company, in Ontario, Canada. The E. coli O157:H7 identified in case patients matched the strain of E. coli O157:H7 that was identified in the salami. A Canada wide recall of the product was initiated.
