European Foulbrood (EFB) Management Guide

These sources provide a comprehensive guide to identifying and managing European foulbrood (EFB), a bacterial infection that targets honey bee larvae. The text highlights diagnostic symptoms such as twisted, discolored larvae in open cells and a patchy "shotgun" brood pattern. To manage the disease, experts recommend the shook swarm method, which involves transferring bees to sterile equipment to purge the infection naturally. While antibiotics were previously common, the sources emphasize that they often merely mask the issue rather than eradicating it. Beekeepers are also encouraged to maintain insurance and contact professional inspectors, as EFB is a highly contagious, notifiable condition. Finally, the material contrasts EFB with similar ailments like American foulbrood and sacbrood to ensure accurate hive assessments.
