Walmart Inc. is recalling around 3,900 bottles of its Better Homes and Gardens-branded room spray due to the possible presence of a rare and dangerous bacteria, the U.S. Consumer Product Safety Commission (CPSC) said Friday.

The U.S. Centers for Disease Control and Prevention has been investigating a cluster of four confirmed cases of melioidosis including two deaths in the country, although the source of these four infections has not been confirmed, the CPSC said.
