Health Canada has been informed that Fresenius Medical Care is voluntarily recalling specific lots of "NaturaLyte Sodium Bicarbonate Liquid Concentrate" in 6.4L and 8L volumes due to bacterial contamination. This product is used as a form of dialysis (hemodialysis) that removes waste products from the blood by passing them out of the body through a filtering system and returning them, cleaned, to the body. The affected product was distributed to hospital and home settings between August 8, 2013 and October 28, 2013. Home care nurses and other all other users should check lots (see below) before administering it.
