June 2, 2013 (San Diego) – If you’ve eaten Townsend Farms Organic Antioxidant Blend frozen berries purchased at Costco in the past couple of weeks, you may have been exposed to hepatitis and should see your doctor immediately. Thus far, 30 cases in five states have been reported, including two in San Diego County. But the disease  can take up to six weeks to occur after exposure, so cases are expected to rise.

One concern is that retailers may have purchased the product in bulk for use in other products such as smoothies or frozen drinks.

Dr. Eric McDonald, the county's deputy public health officer warns that those exposed should seek medical treatment now, which may include  a vaccine for Hepatitis A or treatment with immune globulin – unless you have already had the vaccine or the disease. If you don’t have a healthcare provider, call the County Epidemiology Program at (619) 692-8499.
