Meet Duke, a 4-year-old Angus bull on a South Texas ranch. His owner calls on a July morning because Duke did not come for feed. They find him in the pasture, dead.
But something about this death is deeply wrong.
Dark tarry blood is oozing from Duke’s nose, mouth, and rectum. His body is already bloating despite being dead only hours. When you touch the hindlimbs, there is no rigor mortis. The muscles are completely flaccid.
Your hands stop. Do not touch anything else.
This is anthrax. Caused by Bacillus anthracis, a spore-forming bacterium that has likely been living in this South Texas soil for decades. A summer flood two weeks ago probably brought dormant spores to the surface. Duke grazed them up without knowing.
The most important rule now: do not perform a necropsy. Opening that carcass exposes the vegetative bacteria to oxygen, triggering sporulation and contaminating this soil for another century.
You put on full PPE, collect blood from the jugular vein only, and call the state veterinarian immediately.
💡 The takeaway: When blood comes from every orifice, step back before you step in.
