It may be time to lay off the raw bar. State health officials are warning Colorado citizens [2] of the dangers of eating raw oysters after one person died and nine others were sickened by the bacterium vibrio.

"It's concerning because it's a severe illness. People who are at high risk should not eat raw oysters," Alicia Cronquist, an epidemiologist with the Colorado Department of Public Health and Environment, said.

An 81-year-old Arapahoe County man died after eating raw oysters in a local restaurant. The symptoms of vibrio include diarrhea, nausea, vomiting, chills, and fever.
