Reason

Alere has initiated a recall of the Professional Disposables International (PDI) alcohol prep products due to the potential presence of low levels of the microorganism Bacillus cereus.

Root cause

Material/Component Contamination

Action

Alere sent a recall notification letter dated October 6, 2011, and Verification Form to all affected customers. The letter identified the product, the problem, and the action to be taken by the customer. Customers were instructed to use an alternate prep pad that is not involved with the PDI recall, or use a sterile gauze pad with isopropyl alcohol. If customers purchase alcohol pads from a store or pharmacy, customers can confirm with their pharmacist that the pads they are purchasing are not associated with the PDI recall. INRatio/INRatio2 kits at Alere are currently being reworked to include a sterile PDI alcohol pad. Customers were instructed to complete and FAX the enclosed Verification Form within 10 days to confirm their receipt of the notice and to indicate the number of discarded/required replacement alcohol prep pads. Customers with questions about INRatio/ INRatio 2 were instructed to consult their healthcare provider, or call Alere Technical Service at 877-866-5313 (24 hours a day, 7 days a week).
