Eggs in Derbyshire are being checked to protect consumers.
Derbyshire trading standards officers are carrying out checks to make sure shops and restaurants are selling eggs which comply with the law.
Under the regulations only eggs that meet "Class A" standards should be used and they also need to be labelled and described correctly.
The eggs will be tested to ensure they are as described, for example eggs labelled 'free range' not being produced by caged birds, that they are safe and of the required quality.
Councillor Kevin Parkinson, Derbyshire County Council Cabinet Member for Regeneration, said: "Egg fraud has the potential to be big business and we are working closely with our district council colleagues and the Egg Marketing Inspectorate to protect consumers.
"It's important that shoppers know they're getting what they pay for, that the eggs are safe, of good quality and that they're correctly labelled.
"There's a health issue here and eggs must meet the required standards. Eggs which are not labelled correctly would not be traceable in the event of a health scare."
Councillor Parkinson added: "We must also protect the livelihoods of the retailers and restaurant owners who buy their eggs legitimately. For example, free-range eggs are much more expensive than cage-produced ones and it is important to ensure well-run businesses are not suffering at the hands of fraudulent competitors."
