Well...it can be terribly expensive depending on their setup. I've been in that situation before with warehouse/distribution centers that are built some time ago with no thought to covers or shatterproof bulbs.
To the OP. No, not a requirement in FDA Food Code 2013 or in the new FSMA regulations. However, you will need to address this "hazard" somehow for your FSMA regulations as it is a hazard even though the products are packaged/sealed. What if the glass ends up around the opening of the container, someone opens it, and the glass falls inside? While very rare, it CAN happen. The easiest way is to regularly audit and inspect. Document the inspections and have a documented SOP in the event of breakage.
Per FSMA you will need a food safety plan for the facility. That may only include your glass light hazards. If you have refrigeration for products, that will need to be included as well if any of those products need temperature control for safety (milk/dairy is a good example).
I'm a bit puzzled, why would you not want to have such protected items in a food environment ?
IMEX (and seemingly auditors) it's basic GMP.
