Plastic cutting sheets. how to use properly

The USDA suggests that "all plastic and wooden cutting boards wear out over time. Once cutting boards become excessively worn or develop hard-to-clean grooves, they should be discarded."

Other advice they offer for avoiding food contamination from cutting boards:

Avoid Cross-Contamination The Meat and Poultry Hotline says that consumers may use wood or a nonporous surface for cutting raw meat and poultry. However, consider using one cutting board for fresh produce and bread and a separate one for raw meat, poultry, and seafood. This will prevent bacteria on a cutting board that is used for raw meat, poultry, or seafood from contaminating a food that requires no further cooking.

Cleaning Cutting Boards To keep all cutting boards clean, the Hotline recommends washing them with hot, soapy water after each use; then rinse with clear water and air dry or pat dry with clean paper towels. Nonporous acrylic, plastic, or glass boards and solid wood boards can be washed in a dishwasher (laminated boards may crack and split).

Both wooden and plastic cutting boards can be sanitized with a solution of 1 tablespoon of unscented, liquid chlorine bleach per gallon of water. Flood the surface with the bleach solution and allow it to stand for several minutes. Rinse with clear water and air dry or pat dry with clean paper towels.

While it is impossible to prove a negative, I am unable to locate any credible evidence that there is actual danger from glue in bamboo cutting boards.

Consider that even if (and this seems unlikely) there were formaldehyde in the glue in a cutting board that in order to pose a danger it would have to:

• Not be bound permanently or chemically modified as the glue cures,
• somehow diffuse through the bamboo to the surface,
• transfer into the food in the brief time the food is in contact with the board, and
• do so in sufficient quantities as to cause harm.

I would not worry about this in the slightest.
