The Los Angeles County Department of Public Health is holding clinics over the weekend for consumers who may have been exposed to hepatitis through frozen berries sold at Costco.

At least 30 cases of hepatitis A nationwide may be linked to Townsend Farms Organic Antioxidant Blend frozen berries, including seven confirmed illnesses in California by people who consumed the berries. One of those was in Los Angeles County, two in San Bernardino County and one each in Riverside, San Diego and Humboldt counties, health department officials said.
