Nine Australians have contracted hepatitis A linked to eating contaminated berries from China. Manufacturer Patties Foods has recalled four products including Nanna’s Frozen Mixed Berries and Creative Gourmet brands and Nanna’s raspberries. They are sold in major supermarkets across the country, having been packed in China. Poor hygiene among the workers and potentially contaminated water supplies in China are likely to have caused the outbreak. Hepatitis A is a viral disease that affects the liver, causing abdominal pain, nausea, vomiting, fatigue and jaundice. It has an incubation period of up to 50 days.
