2010-2011 Multistate DeFranco and Sons In Shell Hazelnuts

An outbreak of E. coli O157:H7 was associated with eating in-shell hazelnuts(also known as filberts)purchased from bulk bins in grocery stores or in a repacked form. The E. coli strains isolated from case patients, and from a consumer product sample, matched genetically. The investigation led to a common distributor, DeFranco and Sons, a California based firm. On March 4, 2011, DeFranco and Sons issued a recall of all hazelnut and mixed nut products distributed from November 2, 2010, to December 22, 2010. Only in shell nuts were included in the recall. The nuts were shipped to stores in Minnesota, Iowa, Michigan, Montana, North Dakota, South Dakota, Wisconsin and to Canada. Based on a consumer hazelnut sample that proved to be contaminated with the outbreak strain of E. coli O157:H7, the Minnesota Department of Health traced the hazelnuts to a December 9 shipment from DeFranco and Sons. Later the states of Wisconsin and California isolated the outbreak strain of E. coli O157:H7 from mixed nut samples.
