Food Standards: Labelling & Composition - Honey

These Orders empower the Agriculture Departments of Great Britain to take measures to control American Foul Brood (AFB) and European Foul Brood (EFB), both of which are serious bacterial infections of brood and measures against the Small Hive Beetle (Aethina tumida), and Tropilaelaps Mites. Varroasis (a parasitic mite infestation caused by the parasitic mite Varroa destructor) is no longer notifiable.

Imports of honey bees are controlled by a limited third country system in order to prevent the introduction of exotic bee diseases. Presently only queen bees and attendant worker bees may be imported from selected countries. Only package bees are permitted from New Zealand (a queen plus 15,000 worker bees)
