At least 11 people became ill and two were hospitalized after eating pistachios contaminated with salmonella.
The Centers for Disease Control and Prevention lab traced the pistachios to California-based Paramount Farms.
That's the same farm Trader Joe's and Wonderful Pistachio brands are sourced from. The pistachios are also sold at stores in Canada.
According to the CDC, cases have occurred in nine different states, including Washington, Arizona, North Dakota, Minnesota, Michigan, Connecticut, Virginia, Georgia and Alabama. Arizona and Washington had two cases each. Two people have been hospitalized, but no deaths have been reported, according to the CDC.
The outbreak started in December of last year, and illnesses were reported through early February. Wonderful Pistachios, which owns Paramount Farms, recalled several of its products Wednesday.
Recalled products can be identified by a 13-digit lot code number, which can be found on the lower back or bottom panel of the package. The specific products and lot codes affected can be found here.
In a press release, the company said this is the first time in 30 years one of its products has needed to be recalled.
"Wonderful Pistachios takes food safety matters very seriously and is working closely with health officials to identify the source of the problem," the statement reads. "In an effort to further enhance our food safety program and ensure the health and well being of our consumers, we have, effective immediately, proactively increased our sampling frequencies and lot size testing. The implementation of these augmented safety protocols further exceeds established industry best practices and bolsters our long-standing commitment to producing the highest quality, most wholesome and safest pistachios in the world."
The CDC says this strain of salmonella causes symptoms 12 to 72 hours after eating the tainted food and recommends all pistachios from these brands be returned.
Wonderful Pistachios said the "investigation is ongoing, and we will update the public when more information becomes available."
