Investigators probe blue-streaked mozzarella
Cheese contaminated with bacteria found in supermarket16 August, 18:55
The cheese, purchased by a shopper at a Carrefour supermarket in Turin in June, was traced to a dairy farm and the case is now being probed by prosecutors.
Inspectors found the cheese contained a bacteria called pseudomonas fluorescens, which causes the food to change colour but doesn't usually cause health concerns.
The blue-mozzarella phenomenon is not new in Italy.
A woman outside Salerno found something similar last year when she found blue mozzarella in her packaged cheese container.
And police seized an entire supply of cheese from a supermarket in Frosinone when consumers reported blue cheese.
Similar products were found in 2010 in 14 European countries involving German-made mozzarellas that turned an unsightly inky blue after being opened.
Italian farmers staged protests following that scare, saying the case reflected a deeper problem of typical Italian products being made outside the country to lower standards.
