FDA says that consumers should not purchase or use PNC-27, a product promoted online as a treatment or cure for cancer. An agency drug safety [communication](http://www.fda.gov/Drugs/DrugSafety/ucm536094.htm?source=govdelivery&utm%5Fmedium=email&utm%5Fsource=govdelivery) says that an agency laboratory discovered the bacteria *Variovorax paradoxus* in a PNC-27 solution sample for inhalation. The notice says FDA has not received reports of illnesses or serious adverse events related to PNC-27\. It notes that the product may be available in various dosage forms such as nebulized solution, intravenous solution, vaginal suppository, or rectal suppository. “FDA has not evaluated or approved PNC-27 as safe and effective to treat any disease, including any form of cancer,” it says.
