Are you travelling to the UK?
If you are carrying food products you should check the rules in advance.  It is illegal to take meat or dairy products to the UK from a non-European country.  Also not permitted are fish, shellfish, eggs, honey and certain plants and vegetables.
These controls on foods being brought into the UK are in place to protect the agriculture and the environment of the country, and to protect your health from contagious diseases which are not present in the UK.

Checking before you travel could save you being fined, prosecuted or delayed.
