Surgically Implanted Piercings

Does anyone on this forum have any advice around surgically implanted piercings in a GMP environment?

Are there things that can be done (covering them, specifically with what?) to work around this being as they are surgically implanted?

If they were removable we would just have the employee remove them, but they can’t be removed.

Suggestions?

Health Canada has regulations (as well as the Consumer Safety Bureau in the US) due to some consumer poisonings. Don’t use Cadmium or Lead in manufacturing.
