There aren’t a lot of blue foods.

There was blue string soup in that Bridget Jones movie.

Food safety police in northern Italy seized a batch of 70,000 mozzarella cheeses that turned blue once they were removed from their packaging.

The agriculture ministry announced emergency control measures on the cheese, which was made in Germany for an Italian company that sold it to discount supermarkets in the north of the country.

The cool part is that a consumer alerted authorities in Turin by sending images from her mobile phone of the soft, white cheese immediately turning blue once it came into contact with air.

Those mobile image devices are everywhere and some people know how to use them (not me). So use them when food appears shoddy.

The name of the discount chain that sold the cheese was not disclosed, because it had "managed the situation well" and immediately removed the cheese in question from its shelves, a police statement said.

Managed it well after their cheese was fingered by a consumer with a camera?
