The agency said it was testing to confirm the bacteria in the bottle is the same strain as that seen in the four patients. It previously said lab analyses showed all four infections were closely related.
The spray was made in India. The genetic profile of the bacteria in the spray is similar to that of strains usually found in South Asia, the agency said.
The contaminated spray is labeled “Better Homes & Gardens Lavender & Chamomile Essential Oil Infused Aromatherapy Room Spray with Gemstones,” the CDC said. It was sold for $4 in 55 Walmart stores and on Walmart’s website starting in February and until Thursday.
The Consumer Product Safety Commission and Walmart issued a recall Friday for 3,900 bottles of the spray in six scents. Officials are investigating whether other scents and brands may pose a risk.
Melioidosis is rare in the United States, with about 12 cases reported annually. People can get it through direct contact with contaminated soil and water. The CDC said the infection is treatable if caught early and treated correctly.
