King Bio is voluntarily recalling 32 children's medicines due to microbial contamination, the company said in a release Wednesday. The company said use of the medicines could result in life-threatening infections to some people.

The products were produced between Aug. 1, 2017, and April 2018 and have tested positive for microbial contamination, the company said. Although King Bio describes the number as a "small percentage," it is issuing the recall out of an abundance of caution.
