The process of human composting destroys most harmful pathogens. There are three rare diseases that disqualify a body from undergoing human composting: Ebola, prion diseases such as Creutzfeldt-Jakob Disease, and active tuberculosis.
Monitoring for these diseases is the responsibility of hospitals and medical examiners. For patients who have received radiation seed implants, the seeds must be removed and 30 days pass before they are eligible for human composting.
Most full body donations to science or medical research are embalmed and so are not eligible for human composting. A person can be an organ donor and still choose human composting.
