Can black legs be treated?
Typically, treatment is ineffective against blackleg, and the mortality rate of the disease is relatively high. In some cases, if the disease is detected early enough, penicillin can be effective in saving an animal’s life. A cow that survives blackleg, however, usually suffers from a permanent deformity or lameness.
How does Black Leg occur?
Blackleg is an infectious, non-contagious disease caused by Clostridium chauvoei. Infection occurs when animals ingest bacterial spores while grazing. The bacterial spores penetrate the intestine and are disseminated via the bloodstream to the skeletal muscle, where the spores remain dormant.
How long does black leg last?
Because the disease develops over a short period of time (12 to 48 hours), calves with blackleg are often found dead without any prior signs of trouble. Some calves may recover if treated very early in the course of blackleg with appropriate doses of an antibiotic, such as penicillin.
How can I prevent my legs from getting black?

Later, the skin over the swelling will become cold, dry and leathery. In areas where blackleg is a known problem, it should be suspected in cases of sudden death.
How long does Black Leg stay in the soil?
Spores are very resistant to environmental factors and disinfectants. Older studies confirmed the organism can survive as a spore at least 11 years in better soils.
How do you control blackleg?
There is no effective treatment for either type of blackleg once it has taken hold, so it’s important to prevent it from getting into your garden in the first place. A four year crop rotation will help kill off both forms of the disease, along with planting only certified, disease-free seeds and seed potatoes.
