According to officials, a food handler at the smoothie franchise's store at 1140 Lincoln Ave. tested positive for the disease and was infectious for 12 days this month while working. The employee worked Aug. 1-3, 6-9 and 11-16.
Santa Clara County health officials said the risk that customers had been exposed was negligible, "because it is likely that the employee followed good hand hygiene and food safety practices."
The store was inspected during a routine health inspection July 31, and no violations were found, officials said.
Customers who visited the store within the past two weeks and believe they are at risk of infection should receive a vaccine, officials said. Immune globulin instead of the vaccine is available for infants, people with a chronic liver disease, and those who are over 40, pregnant or immune-system compromised.
Symptoms can include jaundice, fatigue, abdominal pain, loss of appetite, nausea, diarrhea and fever. Anyone with symptoms should contact a doctor. People with hepatitis A can be sick for anywhere from a few weeks to six months. People who have been vaccinated for hepatitis A or have been ill with hepatitis A in the past are not at risk of infection.
Jamba Juice will pay some medical expenses related to treatment, officials said.
