Although glass and brittle plastic are two different substances, they are often used in similar applications in food facilities, and because of this receive similar treatment. All food facilities should establish programs to control the risk of contamination from both glass and brittle plastics.
Relevance and Regulation
The U.S. Code of Federal Regulations (CFR) addresses glass control under “Plant Construction and Design.” This regulation states that “the plant and facilities shall: provide safety-type light bulbs, fixtures, skylights, or other glass suspended over exposed food in any step of preparation or otherwise protect against food contamination in case of glass breakage.”2
CFR also addresses protection against physical contamination, including plastic.
Every food handling and processing facility should have established programs to prevent contamination, including from glass and brittle plastics.
These programs should include the following components:3
- A policy of “no non-essential glass and brittle plastic,” under which the facility recognizes that glass or brittle plastic will be necessary in some cases, but limits their use
- Personnel responsible for approving new ingredients or equipment should evaluate them for non-essential glass or brittle plastic, and substitute another, appropriate material if present
- Develop special handling procedures for essential glass and brittle plastic, such as changing light bulbs
- Any personnel responsible for receiving should be trained in inspecting materials for non-approved glass or brittle plastic, and should be trained on how to respond
- Maintain an inventory of essential glass and brittle plastic used in the facility
- Establish a written procedure on how to respond to a breakage, including cleanup and disposal
- If any ingredients, finished products, or works-in-progress may have been contaminated by the breakage, the affected material must be discarded
- Maintain records of product disposal associated with glass or plastic breakage
Uses that are considered essential may include:
- Overhead and emergency lights
- Forklift headlights
- Light covers
- Gauge covers
- Sight glass
- Computer screens
Personal items are often a source of non-essential glass and brittle plastic.
