Area quarantine explained
Area quarantine is not used as extensively by beekeepers as hive or apiary quarantine, and tends to be limited to outfits with large hive holdings spanning several distinct geographic areas.
An area quarantine might consist of dividing a beekeeping outfit into two parts: those apiaries with a recent history of AFB, and those without. The two parts of the outfit are managed separately, with no interchange of equipment between parts.
Apiaries are added to the AFB-free part if they remain free of the disease for a certain length of time, or are added to the AFB part if a colony develops the disease.
