British egg producers are stepping up their efforts to convince the government to crack down on illegal eggs entering the UK.

As of next year, conventional 'battery' cages will be prohibited, but the UK industry fears some EU producers will flout the rules and continue to use the old, cheaper system.

The British Egg Industry Council said Brussels had still not confirmed a plan of action to prevent illegal eggs coming to the UK, so the British government needed to come up with its own solution.

"We'd like to see a complete ban on eggs and egg products that don't comply," said BEIC CEO Mark Williams. "The government has to come off the fence and find a practical enforcement solution."

To back its case, the BEIC has commissioned a report on the ban from EFFP, which said Scotch eggs and Yorkshire pudding were among the foods most likely to contain illegal egg.
