Genetic testing shows the illnesses were caused by a strain of hepatitis A that has been associated with past outbreaks due to frozen strawberries from Egypt. Upon learning of the potential link to strawberries, Tropical Smoothie Cafe immediately conducted a voluntary product withdrawal of all strawberries sourced from Egypt and found an alternate supply.
Individuals who consumed a smoothie from a Tropical Smoothie Cafe in Virginia that contained frozen strawberries, on August 5, 6, 7 or 8, 2016, may still benefit from vaccine or immune globulin to prevent hepatitis A. (Vaccine or immune globulin administered within two weeks of exposure to hepatitis A virus is effective at preventing the disease.) If you have had hepatitis A or have been vaccinated for hepatitis A, you are already immune and therefore not at risk for getting the disease. Anyone who consumed a smoothie after the frozen strawberries were removed from restaurants is not thought to be at risk for hepatitis A.
Other restaurants, and firms that supply restaurants, may also have received the frozen strawberries imported from Egypt. VDH continues to investigate cases and work with state and federal partners, including the Virginia Department of Agriculture and Consumer Services, the U.S. Food and Drug Administration, and the Centers for Disease Control and Prevention, to identify additional locations where the product may have been distributed.
Anyone who consumed a smoothie with frozen strawberries at a restaurant within the last 50 days is encouraged to watch for symptoms of hepatitis A. If illness occurs, seek medical care and take steps to protect others from the infection.
Hepatitis A is an inflammation of the liver caused by the hepatitis A virus. The classic symptom of hepatitis A is jaundice, which is a yellowing of the skin or the eyes. Other symptoms of hepatitis A include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine and light-colored stools. Symptoms develop 15-50 days after exposure to the virus, which can occur through direct contact with another person who has the infection or by consuming food or drink that has been contaminated with the virus.
Frequent handwashing with soap and warm water after using the bathroom, changing a diaper, or before preparing food can help prevent the spread of hepatitis A.
It is very important for people who have symptoms of hepatitis A to stay home from work, especially if they work in food service.
Routine vaccination against hepatitis A has reduced the risk of this disease in the past decade. Vaccination is available to anyone, but specifically recommended for all children, for travelers to certain countries, and for people at high risk for infection with the virus. Hepatitis A vaccine is available from health care providers (including some pharmacies and travel clinics) to protect against this disease.
