DexCom (DXCM) said Tuesday that two lots of its G7 glucose monitoring sensors designated as scrap were stolen during the destruction process and then sold by third parties.

The company said it is working with the US Food and Drug Administration and other authorities to ensure patient safety and investigate the crime, while notifying clients via several communication channels.

DexCom said it routinely discards sensors that do not meet standards as part of its quality control process and sends these to a third-party vendor for destruction and recycling. Affected lots are 1725204004 and 1725069002, the company said, adding the issue mainly impacts the US.

There have been no reported severe adverse events linked to the stolen products, the company said.
