The Food and Drug Administration advised consumers and healthcare providers Friday to avoid all liquid products made by PharmaTech LLC of Davie, Florida after finding dangerous Burkholderia cepacia bacteria in the water system used to manufacture its products. Those products include liquid drugs and dietary supplements labeled under Rugby Laboratories, Major Pharmaceuticals, and Leader Brands.

An outbreak of B. cepacia infections affecting at least 60 people in eight states led the FDA and Centers for Disease Control and Prevention to PharmaTech. Late last year, the agencies tracked the source to more than 10 lots of PharmaTech’s oral liquid docusate sodium, a stool softener. But suspicion of contamination crept to the company’s other products, and this month PharmaTech issued a voluntary nationwide recall of its other liquid products, such as its liquid vitamin D drops and liquid multivitamins that are marketed for infants and children.

PharmaTech described the recall as a “precautionary measure,” but the FDA seemed to suggest that the problem required more urgency and issued an additional advisory.

“B. cepacia poses a serious threat to vulnerable patients, including infants and young children who still have developing immune systems,” FDA Commissioner Scott Gottlieb said in a statement. “These products were distributed nationwide to retailers, health care facilities, pharmacies and sold online—making it important that parents, patients and health care providers be made aware of the potential risk and immediately stop using these products.”

A representative for PharmaTech reached by Ars declined to comment beyond the recall announcement. The announcement includes a full list of products affected with images.

Burkholderia cepacia poses little risk to healthy people, the CDC notes. But it can be deadly in people with weakened immune systems or other conditions, such as cystic fibrosis. Infections can cause a range of symptoms—from little to none or to severe respiratory distress—and spread from person-to-person or through the environment. The bacteria is known to lurk in health care settings and is often found to be resistant to many common antibiotics.
