Pizza prices set to rocket?

One of the most convenient of home delivery foods, the wonderous pizza, could be about to see prices rise rapidly. According to yesterday's Observer there's a global dairy shortage that is causing cheese prices to rise rapidly and cheese makes up 40% of the cost of a pizza. According to the article in the US a pound of Mozarella has gone from $1.25 wholesale to $4!

This combined with a global rise in the price of wheat means that we could soon be seeing fairly hefty price hikes on our pizzas. Boo.
