The only way to know for sure that an animal has been exposed to anthrax is to consult your private veterinarian. Some clinical symptoms to be aware of are sudden death or severe depression, fever, difficulty breathing, diarrhea, collapse, and convulsions. The key symptom is a bloody discharge from the mouth, nostril, anus, or vulva. If you come across an animal like this, do not touch it. Call your private veterinarian immediately. Anthrax is a reportable disease and must be reported to the state veterinarian or animal health officer in your state.
