Police are investigating a contamination scare at a Safeway supermarket in suburban Melbourne after staff discovered some fresh produce contained foreign objects. The store in Bayswater has issued a product recall where customers who bought fresh fruit or vegetables from the store on Tuesday can return their goods for a full refund. Safeway spokeswoman Clare Buchanan said the problem had been isolated to the Bayswater store, which had reopened this morning. She would not specify what the foreign objects were or the products affected. Police have completed an investigation and the store is re-stocking shelves in the section concerned.
