The New England Compounding Center announced the recall Saturday. The company said in a news release that the move was taken out of an abundance of caution because of the risk of contamination. It says there is no indication that any other products have been contaminated.
The Food and Drug Administration had previously told health professionals not to use any products distributed by the center.
The Centers for Disease Control and Prevention posted updated figures to its website Sunday showing there are 91 confirmed cases of the rare form of fungal meningitis. The outbreak spans nine states and has killed at least seven people.
The states with reported cases are: Florida, Indiana, Maryland, Michigan, Minnesota, North Carolina, Ohio, Tennessee and Virginia.
The steroid linked to the outbreak had already been recalled, and health officials have been scrambling to notify anyone who may have received an injection of it. The Massachusetts pharmacy that made it has said it is cooperating with investigators.
It is not yet known exactly how many people may have been affected, though it could affect hundreds or even thousands of people who received the steroid injections for back pain from July to September.
Meningitis is caused by the inflammation of protective membranes covering the brain and spinal cord. Fungal meningitis is not contagious as are its more common viral and bacterial counterparts.
America's meningitis outbreak has affected another 27 people, bringing the total number of cases to 91 across nine states, Reuters reports. Michigan reported 15 of the new cases, bringing its total to 20, and Virginia added seven more. So far the outbreak has claimed seven lives. The company that produced steroid injections linked to the meningitis—the New England Compounding Center Inc—has halted operations and recalled three lots of methylprednisolone acetatesent sent to 23 states, reports the LA Times.
