TRENTON, N.J. — New Jersey health officials say they’re investigating a possible outbreak of a bloodstream infection involving patients in long-term care facilities and pre-filled saline solutions.

The state Health Department says it has identified two possible cases of infection involving a type of bacteria known as Burkholderia cepacia. They may be linked to pre-filled saline flushes.

The bacteria are resistant to common antibiotics. Individuals with weak immune systems or chronic lung disease may be vulnerable to infection, which can lead to severe respiratory sicknesses, including pneumonia.

Health officials in Pennsylvania and Maryland have notified officials in New Jersey about clusters of bloodstream infections in their states.

Long-term care facilities that received the product on Sept. 30 have been told to avoid using it until further notice.
