Sheila Dillon looks at changes to the UK's egg supply following the EU's ban on battery cages and how the food industry is dealing with shortages and escalating prices.

Although there may still be enough eggs on the shelves of our supermarkets, the programme discovers that egg products used in some of our most popular dishes are in ever shorter supply and some may even be replaced with egg substitute produced by the dairy industry.

Three different food producers explain how the use eggs on a large scale and the impact the EU changes have made on their access to supplies of whole, liquid and frozen products.
