The Food and Drug Administration (FDA) has warned against the purchase or use of PNC-27, a product marketed as a treatment or cure for cancer. A laboratory analysis found the presence of Variovorax paradoxus, a bacteria, in a solution sample for inhalation.

PNC-27 has not been evaluated or approved by the FDA as safe and effective to treat any disease. It is promoted as a tiny, nontoxic protein molecule that attaches to specific receptors only found on cancer cells, causing them to die. Individuals who use a contaminated product are at risk for serious, potentially life-threatening infections. Patient groups at greater risk include young children, the elderly, pregnant women, and the immunocompromised.
