The Trader Joe's berries were shipped to select stores in 26 states and Washington, D.C.Anyone who has these products shouldn't eat them. They can be thrown away or returned to the store for a full refund.The berries may carry E. coli O145, a strain that makes Shiga toxin, a poison that can damage the lining of the gut. Symptoms include severe stomach cramps, vomiting and diarrhea that may be bloody.Most healthy people get better within a week. But some develop hemolytic uremic syndrome, a serious complication that can lead to kidney failure. Young children, older adults and people with weakened immune systems face the highest risk.Symptoms can start a few days after eating contaminated food or as long as nine days later, the FDA says."Consult your healthcare provider immediately if you ate recalled frozen berry products and have any symptoms that resemble an E. coli infection," the agency said.The company described the latest recall expansion as a precaution. It's based on traceback information that tracks contaminated food back through the supply chain and is linked to frozen blueberries recalled in July.That first recall involved GreenWise-brand organic blueberries sold at Publix stores.As of Sept. 21, the outbreak tied to those berries had sickened 17 people in Florida and Georgia. Six were hospitalized, but no deaths were reported.The U.S. Centers for Disease Control and Prevention declared the outbreak over that day, but the supplier continues to issue related recalls.The recalled berries are frozen and have best-by dates stretching into 2028, so they could still be sitting in home freezers, the FDA noted.More informationVisit the U.S. Centers for Disease Control and Prevention for more information about E. coli.SOURCES: Frutas y Hortalizas del Sur S.A., company announcement, Oct. 2, 2026; U.S. Food and Drug Administration, Sept. 21, 2026 .What This Means For YouIf you have frozen organic berries from Walmart or Trader Joe's, check the package against the recall list before eating them, even if you bought them months ago..Sign up for our weekly HealthDay newsletter
