(WASHINGTON) -- Three states and the federal government are investigating an outbreak of E. coli linked to in-shell hazelnuts purchased from bulk food bins at grocery stores. Seven cases have been reported, according to the Minnesota Department of Health, one agency involved in the investigation. Minnesota and Wisconsin both had three cases and one case was reported in Michigan.
"Agriculture agencies in the three states and the California Department of Public Health traced hazelnuts consumed by cases to a common distributor in California, DeFranco and Sons," the Minnesota Department of Health said in a statement Friday. "This firm has recalled all hazelnut and mixed nut products distributed from November 2, 2010, to December 22, 2010. Recalled product was shipped to stores in Minnesota, Iowa, Michigan, Montana, North Dakota, South Dakota, and Wisconsin.”
Consumers are advised to visit the Minnesota Department of Agriculture's website for a full list of stores that sold the nuts.
