PUBLIC HEALTH CONCERNS

There are few public health concerns to the general public in regard to beaver. Trappers and biologists should follow safety rules when dealing with beaver. Beavers can be infected with the bacterial disease tularemia, which is fatal to animals and is transmitted to them by ticks, biting flies and via contaminated water. Animals with this disease may be sluggish, unable to run when disturbed or appear tame. Tularemia may be transmitted to humans if they drink contaminated water, eat under cooked, infected meat, or allow an open cut to contact an infected animal. The most common source of tularemia for humans is to be cut or nicked by a knife when skinning an infected animal. A human who contracts tularemia commonly has a high temperature, headache, body ache, nausea, and sweats. A mild case may be confused with the flu and ignored. Humans can be easily treated with antibiotics. Contact your family doctor immediately if you believe that you have contracted tularemia.
