A total of 11 people infected with the outbreak strain of Salmonella Montevideo have been reported from 9 states.

States reporting illnesses are: Alabama 1, Arizona 2, Connecticut 1, Georgia 1, Michigan 1, Minnesota 1, North Dakota 1, Virginia 1, Washington 2.

CDC is collaborating with public health officials in multiple states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella Montevideo infections.

Illnesses started on dates ranging from December 12, 2015 to February 9, 2016. Ill people range in age from 9 years to 69, with a median age of 31. Seventy-three percent of ill people are male. Among 9 ill people with available information, 2 reported being hospitalized, and no deaths have been reported.

Collaborative investigative efforts of state, local, and federal public health and regulatory officials indicate that pistachios produced by Wonderful Pistachios of Lost Hills, California are a likely source of this outbreak.

Recent laboratory testing isolated the outbreak strain of Salmonella Montevideo from samples of raw pistachios collected from Paramount Farms, where Wonderful pistachios are grown.

On March 9, 2016, Wonderful Pistachios voluntarily recalled a limited number of flavors and sizes of in-shell and shelled pistachios because they may be contaminated with Salmonella. The pistachios were sold under the brand names Wonderful, Paramount Farms, and Trader Joe’s and were sold nationwide and in Canada.
