In cases of an outbreak of HPAI in a holding which consists of two or more separate production units, the competent authority may grant derogations from the measures provided for in the first subparagraph of Article 11(2) for production units containing poultry or other captive birds where no HPAI is suspected, provided that such derogations do not endanger disease control.
Such derogations shall only be granted in respect of two or more separate production units where the official veterinarian, taking account of the structure, size, operation, type of housing, feeding, water source, equipment, staff and visitors to the holding, is satisfied that they are completely independent of other production units in terms of location and day-to-day management of the poultry or other captive birds kept there.
