Carbon monoxide (CO) is a highly toxic, odorless, colorless, and tasteless gas. It is produced by the incomplete burning of fuels, including oil, coal, wood, propane, and natural gas. Inhalation of high levels of CO can lead to CO poisoning and may result in tissue and organ damage.
CO poisoning is responsible for more than 500 deaths and over 20,000 emergency department visits every year. It is the leading cause of accidental poisoning in the U.S. To better understand the impact of CO poisoning, the California Environmental Health Tracking Program (CEHTP) is providing data and information to help track CO poisoning in California.
