U.S. and Canadian regulators are investigating a hepatitis outbreak that may be linked to fresh organic strawberries. In a joint weekend statement, the U.S. Food and Drug Administration and the Public Health Agency of Canada say at least 27 illnesses in Minnesota, California and Canada occurred after people ate FreshKampo and H-E-B brand strawberries. The strawberries were purchased between March 5 and April 25 at various U.S. retailers, including Aldi, Kroger and Walmart and at Co-op stores in Canada. The strawberries are past their shelf life, but the FDA says consumers who froze them to eat later should throw them away.
