Health officials on Thursday reported an outbreak of bacterial infections in people who got injections of stem cells derived from umbilical cord blood.

At least 12 patients in three states — Florida, Texas and Arizona — became infected after getting injections for problems like joint and back pain, the Centers for Disease Control and Prevention said. All 12 were hospitalized, three of them for a month or longer. None died.

Investigators don’t think the contamination occurred at the clinics where the shots were given, because they found bacteria in unopened vials provided by the distributor, Liveyon, based in Yorba Linda, California.

Liveyon voluntarily recalled the stem cells in October.
