Idaho-based Evergreen Fresh Sprouts, LLC recalled the sprouts distributed in Washington and Idaho due to potential contamination connected to a Salmonella outbreak reported in 5 states.

“While no samples of Evergreen sprouts have tested positive for Salmonella at this time, epidemiological evidence indicates that Evergreen Produce Alfalfa Sprouts and Spicy Sprouts are the common food eaten by the people infected with the outbreak strain of Salmonella enteritidis,” a FDA statement said.

The FDA reported that tests of Evergreen sprouts are still pending.

The outbreak of Salmonella Enteritidis has caused 21 reported cases as of June 27, including three hospitalizations, in Idaho, Montana, New Jersey, North Dakota and Washington, according to the Centers for Disease Control and Prevention.

On Monday U.S. health regulators advised people not to eat alfalfa or spicy sprouts under the Evergreen Produce brand as they investigated a possible link to the salmonella outbreak.

The five-state outbreak may be linked to sprouts sold in plastic bags labeled “Evergreen Produce” or “Evergreen Produce Inc,” according to the CDC.
