The U.S. Centers for Disease Control and Prevention confirmed Wednesday that frozen strawberries imported from Egypt are the cause of an outbreak of hepatitis A spanning six states. The outbreak was initially traced to smoothies from certain Tropical Smoothie Café restaurants, but upon further investigation, the CDC deduced that the imported berries in the smoothies were the cause. An estimated 55 people people have gotten sick, with the majority of those cases in Virginia, where the outbreak originated.
