Frozen blueberries distributed in four states have been voluntarily recalled due to possible listeria contamination.
Oregon Potato Company, which owns the Salem, Oregon-based Willamette Valley Fruit Company, voluntarily recalled 55,689 pounds of frozen blueberries on Feb. 12 over potential contamination with Listeria monocytogenes, according an enforcement report from the U.S. Food and Drug Administration.
The recall was designated as a Class I recall on Feb. 24, the highest FDA classification, which indicates that "use of or exposure to" the affected product can cause "serious adverse health consequences or death."
The voluntary recall impacts blueberries distributed to Michigan, Oregon, Washington and Wisconsin, as well as Canada, the FDA report states.
The product was not sold to consumers from retail stores, according to the FDA.
Recalled berries were packed in 30-pound corrugated cases and 1,400-pound totes of individually quick frozen blueberries.
Lot codes and best-by dates can be found on the FDA website.
The company has not issued a public press release on the recall. Willamette Valley Fruit Company did not immediately respond to ABC News' request for comment.
Listeria is a bacteria that when ingested can cause an infection known as listeriosis, according to the Centers for Disease Control and Prevention.
The condition is most dangerous for pregnant people, newborns, people with weakened immune systems and adults 65 or older, the agency states. For people who are pregnant, being infected with listeria can cause pregnancy loss or premature birth.
According to the CDC, an estimated 1,250 people get listeriosis annually in the U.S., and about 172 people die from it.
