Eleven people in Indiana, Nebraska and Wisconsin became infected with hepatitis A after eating blackberries from Fresh Thyme Fresh Market grocery stores, according to federal health officials.
Earlier this week, frozen raspberries and mixed berries were recalled from Aldi grocery stores for hepatitis A contamination.
The outbreak has prompted a recall of berries sold between Sept. 9 and Sept. 30 at Fresh Thyme stores in 11 states including Ohio, Pennsylvania and Missouri, according to the U.S. Food and Drug Administration.
Hepatitis A is a contagious virus that affects the liver and can range in severity from a few weeks to several months, officials said.
