(UPDATED COVERAGE, March 10) E. coli-contaminated hazelnut samples taken from an ill Minnesota resident's home match the DNA fingerprint of the bacteria that sickened seven people in three states, the Minnesota Department of Agriculture reports.

DeFranco & Sons Inc., Los Angeles, had earlier issued a voluntary recall of products containing hazelnuts - also known as filberts - linked to the E. coli O157:H7 outbreak. There are three cases each in Minnesota and Wisconsin, plus one in Michigan.

The Minnesota officials traced the samples to a Dec. 9 shipment from DeFranco & Sons, according to a news release. The recalled hazelnuts are in shell and were distributed under several labels between Nov. 2 and Dec. 22, according to the Food and Drug Administration.

The bagged recalled items include 1-pound hazelnuts under the Sunripe label and 1- and 2-pound mixed nuts under the same label. Also affected are 4-pound mixed nuts sold in gift packs under the Season’s Greetings label. All of those products have the use-by date of June 30.

The suspected nuts also were sold in 50-pound bulk as Imperial Mixed Nuts or Supreme Mixed Nuts. Also distributed were 50-pound bags of hazelnuts under the George Packing label. Those products may have been repacked into smaller bags, according to the news release.

The nuts were sold to retailers and distributors in the U.S. and Canada.

Consumers who purchased in shell hazelnuts or mixed nuts are urged by the FDA to discard the items or to check with the retailer to determine if the nuts are among those being recalled.
