European foulbrood is often considered a "stress" disease—dangerous only if the colony is already under stress for other reasons. An otherwise healthy colony can usually survive European foulbrood. Chemical treatment with oxytetracycline hydrochloride may control an outbreak of the disease, but honey from treated colonies could have chemical residues from the treatment. The "Shook Swarm" technique of bee husbandry can also effectively control the disease, with the advantage of avoiding the use of chemicals. Prophylactic treatments are not recommended as they lead to resistant bacteria.
